Diving in California

David Mansfield1 comment

As humans, we often find ourselves drawn to activities, ideas, objects and places greater than ourselves. A beautiful sunset, getting a spaceship to Mars, finding ways to live a good life are all fulfilling characteristics of the human existence. Diving in California is no different. With the landscapes drastically changing from tip to tip, California offers divers an amazing view of the ocean in all of its wonder. A large number of divers find themselves drawn back into the cool waters time and again.

If there was something greater than ourselves, it would be the Pacific Ocean.  The largest and deepest ocean on the earth, the Pacific consists of 60 million square miles and averages a depth of 13,000 feet; covering more than 30% of earth.¹ More amazing is the fact that humans have spent millions of years on earth and have yet to breakthrough the entirety of its exploration. With the extreme depth of the Mariana trench (7 miles deep by 1500 miles wide) and its overall vastness, there are many areas of our ocean that remain unexplored and fully understood by humans. As of 2015, there were 228,450 known species in the ocean with as many as 2 million more remaining a total mystery.² Scientists are still discovering species every single day! Greater than ourselves indeed. 

The most common comment we find is "diversity". The protected waters found throughout Southern California create a region of diving that is so biodiverse that most divers are amazed at the amount of life found in the smallest areas. From a healthy nudibranch population to vast kelp beds, Southern California's aquatic life find abundant areas offer food sources and protection for thousands of species. These waters are teeming with life! On a single boat trip, you'll see tons of beautiful fish and fauna followed by schools of dolphins and flocks of birds hunting out in the ocean while on a surface interval.   

Getting here - Southern California has some of the busiest airports in the world. From San Diego to Los Angeles, one may find a cheap flight at these international hubs to arrive and explore. Those divers interested in San Diego can visit such sites as Wreck Alley or the Point Loma Kelp beds for amazing shots and exploration of wrecks. Those arriving in Los Angeles can explore Catalina through the port of San Pedro/Long Beach/Dana Point or check out lobster diving favorites like Anaheim's breakwall! If you are looking to get closer to the action, the Santa Ana and Long Beach airports are smaller hubs that have direct flights throughout the region. From there, it's a quick jaunt to some of the most amazing diving Southern California has to offer. Dive sites like Diver's Cove, Heisler Park, Deadman's Reef litter the entire coastline and yearn for diver attention every single day! 

If you are looking to truly explore, there are many untouched realms in Southern California. Technical divers are still finding deeper wrecks on a regular basis and trying to identify them for further exploration. For those not looking to go deep, the islands of San Clemente, Catalina, Coronados and much more are still under exploration. We've even got oil rigs that divers visit on a regular basis to discover new species and take amazing shots of the rigs and the abundance of life.

If you are looking for a truly amazing experience both top and bottom, Southern California needs to take its place on your bucket list. Hop on a plane, train or automobile and come on out! 


The divers of Southern California would love to host you and your family on the next diving adventure!

Southern California's best dive encounters

David Mansfield1 comment

California is home to a highly diverse scenery above and below the waves. Northern California is covered in Giant Redwood forests and sweeping views of rugged terrain. Areas like Monterrey, Big Sur and Point Lobos State Natural Reserve provide divers an amazing view of a protected underwater realm. Meanwhile, the Central Coast of California is a gateway to the Channel Islands, where one of the largest Marine preserves in the country reside. Large animals like Orcas and the Grey Whale travel through the Channel Islands and grace bubble-makers with an unparalleled diving experience! As a traveler moves further south along the longest continuous state coastline in America, they'll find more beautiful water and enjoy many amazing areas that span from San Diego to Los Angeles. There is no doubt in any diver's mind that Southern California is a unique diving experience that must be jotted down on a bucket list and achieved! Whether you are looking for deep wrecks, kelp forests or swimming with some very large animals; you'll find it in SoCal. 

Millions of underwater inhabitants allow a diver to enjoy substantial viewings in a short amount of time and give divers plenty to talk about when they surface on the world-class beachheads to spend the rest of their day!

Here's a few of Southern California diver's favorite encounters! 

The "big'uns":

Giant Black Sea Bass

Giant Black Sea Bass

Meet Stereolepis gigas. Commonly known as the Giant Black Sea Bass (GSB), this behemoth can reach lengths of 7ft and weigh as much as 700lbs. This fish was sought after by fishermen and eventually found itself on an endangered species list; this prompted the California Department of Fish and Game to ban the fishing of the GSB in 1982. Slowly, but surely, the population is finding itself back in a common sighting for SoCal divers. The GSB find hunting grounds amongst shallow rocky reefs in California and tend to stay in their areas for some time. They utilize their giant maw to rapidly suck a prey into their mouths for feeding and they love to eat just about anything on the reef.  At the time of this writing, GSB's are currently hanging out at the Casino Point in Catalina and along the California coast at Heisler Park. They are a curious fish that will circle a diver and inspect them with their large eyes before moving along elsewhere along the reef. They are quite a treat to see on a dive!

Sea Lions

California Sea Lions

Zalophus californianus is a carnivore that is very common along Southern California shorelines. They can live up to 30 years of age and weigh in at a whopping 800+ lbs upon full maturity. The California Sea Lion is the fastest of its family where it can reach speeds of 25 miles an hour. They are a social animal that many top-siders can enjoy as they lay about on docks, moorings, rocks and more. They are extremely smart hunters and can remain below the surface for 10 minutes. They are the ire of fishing boats, as sea lions will comfortably chill below a boat and snag fighting fish directly off reels for some lazy meals. The California Sea Lions are always fun to interact with but do require caution as they are a territorial wild animal. Divers in Southern California will travel to the Los Coronados Islands, La Jolla Cove, San Clemente's Seal Rock and Crescent Bay North's Seal Rock for a chance to encounter these animals. At Shaw's Cove, it is not uncommon to have a Sea Lion join a diver on a night dive. The resident there enjoys using a diver's lights to help hunt!

Pacific White-Sided Dolphin

Pacific White-Sided Dolphin

Lagenorhynchus obliquidens is known as the Pacific White-Sided Dolphin and are protected by the Marine Mammal Protection Act. They are most noticeable in California waters because of their white stripes when they are cresting the surface of the water or viewed underneath the waves. They have a short beak and look very similar to a porpoise. The Pacific White-Sided Dolphin is highly sociable and is often viewed by boaters when the dolphins decide to surf the wakes of their boats. They are not shy when it comes to acrobatic maneuvers and often hunt in groups, which provide amazing views for observers. Surfers and divers alike will experience close encounters with a dolphin and there are many tales of watching dolphins surf the waves along the SoCal coastline. They are always fun to see under the water!

Grey Whale

Gray Whale

Eschrichtius robustus is an amazing thing to see in Southern California waters. This animal travels between Mexico and Alaska and provide whale watching tours a view unlike any other. Reaching 30-40 tons and 40-50 feet, a Gray Whale is a very noticeable passerby in Southern California. They are often covered in organisms and will provide onlookers with views of their tails (also known as flukes) and gigantic blowholes when they surface for air. Their two blowholes are positioned in such a way that when they exhale, their spout appears to be heart shaped. For Southern California divers, a gray whale is so large that it often creates a visual disturbance in the water when it passes. An animal that exceeds the length of full size school busses are wary of boats and will often travel or dive well away from them. On occasion, divers and sight-seers will get to enjoy a breaching whale or catch a glimpse of their beautiful flukes.

The common ones:

Pacific Barracuda

Sphyraena Argentea is a schooling fish that is often found in large packs throughout Southern California. It is a predatory fish that spans from the southern tip of Baja Mexico all the way up to coastal Washington state. They can grow to over 3ft long and weigh in at 15lbs. During winter, the Pacific Barracuda will move south to warmer hunting grounds before moving back into our favorite Southern California dives sites and becoming a treat to see while out in the water. These fish are aggressive hunters of smaller fish and are inquisitive by nature. They are attracted to shiny objects and will come close to a diver to take a look. Considering their sharp teeth, it is safer to maintain a distance and enjoy their beautiful views from afar!

Garibaldi

The Elusive Garibaldi

Hypsypops rubicundus can be easily identified by its bright orange coloration and inquisitive personality. Unlike other damselfish, who reside in warm tropical waters, Garibaldi can be found in temperate waters off the California coast from Monterey Bay down to the northern Baja coastline waters of Mexico. After over two decades of the Aquarium industry aggressively targeting the Garibaldi, California passed legislation in 1993 to protect these fabulous fish. In 1995, the Garibaldi was officially named the California State Marine Fish and are completely protected under state law from being removed from their habitats. The male Garibaldi is the housemaker of a mating pair. Not only does he select the nesting area, but he thoroughly prepares and maintains the area for the female to lay her eggs. Garibaldi are also very territorial and have meticulous boundaries of where one nest ends and the other begins. Be careful not to get too close! They have been known to chase divers away from their nesting areas. One of the authors may have been bitten by a combative garibaldi while photographing its nest. If you are diving in California, you can bet you will be able to see some of these vibrant fish!

Sheephead

California Sheephead

Semicossyphus pulcher are an incredibly long-lived fish species that inhabits the rocky reef and kelp beds of California. Its maximum known lifespan in the wild is 53 years! However, most Sheephead do not reach this age due to fishing demands. Males can be distinguished by their black and orange midsection, white chin, red eyes and prominent bulbous foreheads. Females are typically smaller than the males and are more of a dull pink in color with white undersides. These fish are sequentially hermaphroditic as adults. Which means they are all born female and can develop into a fully functioning male after reaching a certain maturity level and size. Environmental conditions and the ratio of males to females in their local populations spark this unidirectional sex change. As a male, this fish establishes a spawning territory during mating season and protects a group of females with which he breeds. If you’re diving in California, you’re likely to see at least one of these canine-toothed fish!

_________________________________________________________________

Moray Eel

The California Moray Eel

Gymnothorax mordax is a long, slim snakelike fish that is light to dark brown or green in color. Divers will typically find them tucked away in crevices during the day and prowling the reef for prey at night. The moray eel lacks pelvic fins, pectoral fins and gill covers. Most fish breathe by opening and closing their gill covers to force water over their gills. Since moray eels lack gill covers, they constantly open and close their mouths to push water over their gills, so it appears to be regularly gasping for breath (or waiting for the end of a bad joke). Scientists hypothesize that the California Moray’s off the Southern California Coast do not reproduce – possibly due to the cold-water temperatures. Moray’s living here are thought to hatch off the coast of Baja California and drift north as larvae.  A distinguishable feature of the moray eel is the “second set” of jaws located in the back of their throat, also known as pharyngeal jaws. When the eel’s front jaws bite into its prey, the pharyngeal jaws spring forward and latch onto the prey while dragging them deeper into the moray’s throat. Along with their two sets of jaws, moray’s also have dagger-like teeth that are full of bacteria. Even though a moray will not bite unless provoked, be sure to keep your hands to yourself and do not reach into moray territory crevices.

Octopus

Pacific Red Octopus

Octopus rubescens is known as the Pacific Red Octopus and can be found from Alaska to Baja California on the sandy or rocky bottoms of kelp forests to depths of 200m. This octopus is best identified by having three "eyelashes," or papillae, underneath its eyes and is typically red or brown in color. With arms around four times the length of its body, they typically hunt for marine invertebrates (crabs being a particular favorite) and fishes late into the night. Not only do octopuses have excellent sight, but they use each suction cup to taste, smell, and sense their surroundings. Be careful not to touch these guys! They have a powerful venom filled beak that they use to penetrate and poison their prey. Octopuses are gonochoric, where both male and female adults usually die shortly after spawning and brooding. They are considered to be the smartest invertebrate species, and potentially as intelligent as a house cat. However, not nearly as fluffy.

The "itty-bitty'uns":

Spanish Shawl

The Spanish Shawl

Flabellinopsis iodinea is a species of aeolid nudibranch that is so vibrant it will stop divers in their tracks! The body of the Spanish Shawl Nudibranch is translucent purple with intense orange cerata emerging from its back. Located on the top of the nudibranchs head are deep orange/red rhinophores that they use for navigation, finding mates and prey. They typically feed on tiny hydrozoan colonies that grow on kelp and will store the stinging cell from these hydrozoans and use it in their own cerata as a defense mechanism. Various species of nudibranchs often use this chemical sequestration process as they lack the physical protection of a shell. This nudibranch, like many other seal slugs, are hermaphroditic. Each nudibranch possesses both male and female reproductive organs on the right side of their heads. Self-fertilization is possible in many nudibranch species however it is extremely rare. On your next dive, slow down and keep your eyes out for these colorful beauties.

Mantis Shrimp

Hemisquilla californiensis can grow up to 12 inches long and can be found from silty shallow water to depths of 295ft from Point Conception to Panama. The California Mantis “Shrimp” is actually not a shrimp at all! True shrimp are Decapods that have ten legs with three pairs that have developed into mouthparts. Stomatopods, like the Mantis Shrimp, have only three walking legs while the rest are converted into feeding appendages. These tenacious shrimp have the ability to break glass up to one-quarter inch thick. For diver’s, finding this shrimp in the open is a treat! They are incredibly quick and prefer to burrow more than six feet long in soft, silty substrates. This resourceful shrimp likes its privacy and can conceal their burrows by placing shells and other debris over the openings. Similar to the American lobster, the Mantis Shrimp can produce distinct sounds by vibrating its carapace. Scientists have recorded that each individual animal produces a unique rumble sound, and that this acoustic activity is higher during dawn and dusk, times when they are feeding or guarding their burrows. Listen closely on your next night dive!

Catalina Goby

The Catalina Goby

Lythrypnus dalli is a small vibrant fish that almost never leaves direct contact with the rocky reef structures of the eastern Pacific Ocean. The Catalina Goby, or Bluebanded Goby, often hide near or under sea urchin spines (or the crevices that the sea urchins create), and do not like to stray far from these protective structures. This fish can be distinguished by their small stature, bright orange body coloration and electric blue striping. Another particularly interesting characteristic of this goby is its ability to rapidly change sex. Many marine fishes are able to change sex, but nearly all of these species are only able to change in one direction. As a bidirectional hermaphrodite, the Catalina Goby can change their sex back and forth within just a few days. This trait is eminent to these goby considering they rarely venture far from their territories, and this facilitates reproduction with nearby individuals.

Life in the Scuba Shop

David Mansfield

The Scuba Diving industry is unique. It is designed to provide an unparalleled experience in a world unlike the one humans reside. Divers trade their tennis shoes for a pair of neoprene booties and strap on equipment designed to keep them comfortably breathing underwater. Through the use of an amazing invention, almost any person can dip below the waves to experience the underwater realm at its finest. With emerging technologies, we find scuba divers constantly pushing towards the greater effort of the human experience. Unique indeed...

Diving is not the newest of activities. Through technological advances it has increased in popularity in the last 70 years. We find humans underwater in many places around the world and we find that scuba diving crosses many disciplines. Commercial divers find themselves at great depths conducting work on pylons, pumps and more. Pool gals and guys have jobs that require them to dip below the water line to repair pumps and lights. Technical divers explore depths that include deeper reefs and wrecks throughout the world. Meanwhile, the "reef crawlers" of our very large recreational diving community find themselves exploring new places every single day. Police, fire and lifeguard departments around the world rely on their dive teams to conduct search and rescue as well as emergencies that are water related. There is no doubt that scuba diving is an inherent part of our world today.

Our massive scuba family sees each other on beaches, boats, far-off lands, etc. The techniques of scuba are constantly evolving and the demands of each diver run the gamut from photography to spearfishing to repairing drainage pipes. 

All of this is supported and maintained at the scuba shop near you. 

When you enter a dive shop, they do not look like the typical retail centers found in malls across the world. They have gear everywhere. Items awaiting service, items for sale, older items waiting to go somewhere, shipments coming in and shipments going out; the list is endless. Hundreds of products ranging from dive computers to knives to wetsuits adorn the walls and displays throughout the entire square footage of the shop.

A smiling clerk awaits the patrons and helps determine the needs of each and every client. From a stainless steel bolt to a full compliment of rebreather dive gear, the employee is expected to know it all. They hone their profession through years of practice and actual application. A great deal of individuals who work in the scuba industry are dive professionals. When helping consumers invest, many of the people working in a dive shop are currently using that piece of gear or their hair is still wet because they snuck in a local dive in Orange County before work! The dive shops located in Southern California are no different. You may wander into one and find a full compliment of fins and snorkels while another specializes in spearguns and teaching freediving classes. Overall, the dive shops of Southern California attempt to flow with their customer base and provide the equipment that is currently in demand. That smiling clerk needs to know a lot of information to keep the general population interested and intrigued. 

Scuba Diver

 

With hundreds of manufacturers who carry hundreds of products; it is a whirlwind of knowledge and understanding to a newcomer in the dive industry. At Beach Cities Scuba, new employees are subjected to many types of gear and techniques during their tenure. From fitting for a new mask or high-tech new fin technologies, we find many dive shop employees on a constant race to keep up with the growing trends and popular items. This is what makes the dive industry so unique. There are not too many places in the world where retailers are expected to know the full capacity of 8,000 completely different products inside a store. Couple that with California diving and you can see the increase in equipment needs and knowledge! Within just a few years, a newcomer will become a professional on diving techniques and knowledge within the industry!

The dive shop has more than just a good sales staff supporting it. There are service technicians who spend many hours ensuring top quality function. As many divers know, neglecting scuba equipment is not advisable when scuba diving on a regular basis; we need our gear working in top notch order to ensure our safety and enjoyment of every dive conducted throughout Southern California. There are boat captains who venture throughout our Pacific coastline looking for wrecks, reefs and anything that provides a substantial blip on the side scan sonar. These individuals spend many hours honing their profession in order to safely deliver and return divers who explore our local dive sites like Laguna Beach. There are trainers who hone the craft of teaching the art of scuba diving and ensuring a safe environment for all participants. Outside of the dive shop, we have manufacturers, sales representatives, speakers, specialists and much more providing secondary support efforts for each dive shop throughout the country. As one can surmise, when a diver signs up for a diving class, it takes a myriad of people to support this fun and exciting effort we know as scuba diving! 

Divers in Class


Scuba shops around the world are focused on delivering quality training and product to their customers. Whether you are venturing into Laguna Beach to go snorkeling or looking for the nearest PADI certification program, you'll find an outfit ready to help out to the best of their abilities. It is true that Orange County scuba shops compete for customer business, but it is also true that they all know each other and realize that their service areas are the most important thing to them. Your local dive shop depends on seeing a customer's tank for airfills and opportunities to sell high quality diving equipment to continue this wonderful experience we call scuba! Whenever you find yourself in a dive shop in Southern California, take a moment to meet them, see what events they have coming up and their latest technology on the market. You'll help that sales person present their products and start the process of creating an important bond between scuba shop and scuba diver!

Throughout the years, life in the scuba shop is a hectic experience that requires a professionalism that keeps student divers safe and sound while they explore Orange County dive sites and more. The adventures will continue to occur as long as groups of divers continue getting together and finding excuses to dip below the waves of our beautiful beaches and dive sites. The author can speak for any dive shop out there. Their favorite thing in the world is supporting divers both new and old. There's nothing more exciting than seeing a new diver experience the underwater world for the first time. In the end, the dive industry is very unique and can support many types of divers around the world. Venture into one today!!!

Benefits of becoming a scuba diver

David Mansfield

Our lives are driven by purpose. The ability to make a difference and to explore are just a few of the reasons the human endeavor continues to burn at its very core. If you believe this, you have much in common with scuba divers. 

Many parts of our world remain undiscovered. Our species tends to congregate within our own support networks and live "on the grid". That untouched experience is oftentimes more rare when one submerges into the great blue. The scuba diver that seeks new reef systems, wrecks and more will discover a world rarely seen by others. In some cases, a diver can submerge into a local area never seen by members of their species! It is that exploration and purpose that drives the sport of scuba diving.  

With so much to explore, it is not a surprise to see divers continuing their experience and education to reach new depths and conduct fresh activities all over the world. Lakes, quarries, mines, rivers, oceans are among the collection of places to swim anew or continue to enjoy for years.  

There are some other great benefits of becoming a scuba diver. Here are reasons we hear often from our community! Enjoy! 

1. Quiet place. In today's bustling world, we find social/familial commitments, traffic from vehicles, work requirements and much more eroding our peace. Many divers find the underwater realm cathartic and purifying. As ocean life drifts along the diver's view and the sounds of slow breathing from the regulator persist, we find calm. Our body relaxes and we realize that we are part of something greater than us. Something greater than that crazy world above.

2. Weightlessness. As a human ages, they find joint pains and muscle soreness from the persistent pull of the earth's gravity on the body. For some divers, they experience an almost instant relief from those little pangs when they enter the world of scuba diving. With proper buoyancy control, a scuba diver suspends virtually weightless within the water column. This floating sensation gives many divers an excellent relief! Obviously, no diver should dive with a legitimate injury as it can be exasperated by the act. However, we find that all divers enjoy that feeling of weightlessness when they achieve it. 

3. Activities. The scuba world isn't just throwing on a bunch of gear and getting wet. Exploring the world's largest lead mind in Bonne Terre, Missouri; seeing a tiger shark for the first time in the Bahamas; looking at the beautiful kelp forests of Southern California; the list is endless when it comes to experiencing the underwater realm. Whether you want to swiftly drift along currents, see a cenote in Mexico or check out missile silos in Texas; there's an activity for every diver! We are only limited by our training, experience and ability to travel. Any active diver will proudly talk about their last dive trip, whether that was the SS Thistlegorm in Egypt or in a quarry in Illinois. The activities become almost endless when it comes to the scuba world.   

4. Education. You learn so much as a scuba diver. A majority of divers understand basic concepts of the environment, physics, physiology and theoretical dive planning. Knowing how the body acts under the sea becomes a base knowledge requirement for certification. Though we have little sayings like "Never hold your breath", they are all tied to physiological reasoning. A majority of divers understand this concept and are quick to tell you the reasons why you would do or not do something. For those seeking out further education, we find dive agencies offering a myriad of courses designed to whet the appetite of the educationally minded individual. Want to learn underwater photography? Explore a World War 2 wreck? Try on a drysuit? The educational opportunities are endless as well! 

5. You're now cool. If you're looking for a way to be better than you already are, scuba diving might be for you! You'll get questions like; "How much oxygen do you have?" You'll experience compliments like, "Wow! That wetsuit looks really nice on you!" - more importantly, you'll join approximately 3.2 million other humans on earth who've taken the plunge. Donning the equipment, seeing exciting things underwater, visualizing the crew members working on a ship of the past as you swim through the hallways in the present are among the coolest things to do. As you share your videos, photos and tell the tall stories that come with your adventurous lifestyle, there will be no doubt that you hold the title for the coolest person in the room.  

6. History lessons. Many divers love to see wreck dives. Learning the history of the vessel and how it sunk become standalone history lessons for a diver. In Southern California, there's a wreck known as the UB88, it is a World War I era German submarine and the only known 'enemy' ship to reach the California coastline. Today, rebreather divers and technical divers will don their equipment and explore the boat as the conning tower still stands erect in 200' of seawater. Other wrecks throughout the world tell a story. Whether they wrecked in the middle of the night along a sandbar in North Carolina or were intentionally sunk by a captive German crew in World War I in Scapa Flow, Scotland; each wreck gives the diver a history lesson that extends far from the pages of a book. 

7. Social. Though this list isn't in any kind of popularity order, it is well known that the scuba community is like a family in many respects. The social aspects of scuba diving are anchored to the common experiences from a dive. As divers return from their exploration, they share stories and compare the things they accomplished on their dive. One group may have seen a beautiful ray while the other enjoyed seeing the sea lions frolic in front of their cameras. For those divers who regularly dive together, they forge a unique bond that expands trust and communication. In many cases, these shared experiences build upon lifelong friendships. It isn't rare to see a group of divers spend many years together and travel throughout the world exploring the oceans.  

Regardless of your reasoning, it can be firmly stated that there are some great benefits to becoming a scuba diver. If you are looking for a sport that can provide you an entirely new world of discovery, you might find that enjoyment in scuba diving for education, training or experiences, our dive world will provide! Or maybe you just need a new social scene! Whatever your interest, you may want to look into becoming a scuba diver!

Scuba Diving in Laguna Beach, California

David Mansfield1 comment

Sam looked out over the shoreline assessing the wave sets as they came in one after the other on Memorial Day. There were no stairs or parking meters like you see today. Sam had climbed down a "cliff" to arrive at this beachhead. The visibility was about 10 miles across the ocean. Catalina island was barely visible in the distance as he looked over Diver's Cove. The heat was climbing towards 75°F by mid-day, but Sam was weathering the low 60's at this moment. He knew the water would be chilly, so he donned a government issue sweater he nabbed from a surplus store to use as thermal protection. Up to this point, Sam was an avid goggler for almost 7 years. The water was his sanctuary, the exploration; his passion. Strapping on a mask and fins (WWII surplus items), he saddled his borrowed "lung" and prepared to dive this super popular site in Laguna Beach, California. It was 1951. It was also Sam's first dive.  

Samuel Miller III
California is well-known for its bountiful harvests of seafood. In the early days of development of California's shoreline, fisherman would search up and down the coast on trawlers or armed with a Hawaiian sling to take advantage of this vast food supply. In 1948, James Dugan wrote an article in science illustrated called "The first of the men fish"; this would open up American eyes to a new type of sport. Men searching for a tactical advantage against fish, were now privy to an entirely different method of fishing. Others would take up photography, establishing training organizations for the public or dedicate their life to exploration of a world beyond; right in their backyard. The United States scuba divers could now crawl the shorelines and take boats to explore areas of Laguna Beach and beyond in California. Even in those days, many scuba divers created their own contraptions to make scuba diving possible. Sam wasn't the first diver to breach the waters of Diver's Cove, and he wouldn't be the last. Men and women like Sam would go on to grow the Orange County diving community and literally create a sport right here in the waters we dive everyday. 
 
Ron Merker

Rapidly following, EDCO would produce its first wetsuit in 1953 and business owners like the legendary Ron Merker would take to the scuba scene in Orange County with an unparalleled passion for the sport. One of Ron's stores, the Aquatic Center still stands and is operating in Newport Beach under the ownership of Beach Cities Scuba. 

Pioneers and legends of the Southern California dive scene spans among explorers, boat captains, business owners, photographers, writers, actors/actresses and founders of some of the largest scuba training organizations of today. Dottie Frazier, Roger Hess, Sam Miller (and son), Ralph Erickson and John Cronin are just a smattering of names who explored Laguna Beach and the surrounding areas of Southern California. More importantly, they contributed to the sport and subsequent growth of the scuba industry.

The entire sport that you see today was born right here. Many of today's dive sites are named by these individuals and found on websites or the famous Franko's map of Orange County. Young, enthusiastic divers these days are able to enjoy the sport thanks to pioneers who dived these same waters and developed the tools, training and safety procedures of yesterday.  

For those in the know; Southern California was, and still is, one of the greatest areas in the world for scuba diving adventures. Travelers often marvel at the amazing sunsets along the 900 mile stretch of the Pacific coastline. For Laguna Beach divers, their beaches face generally south allowing for beautiful sunrises and sunsets all along the shoreline. The real beauty resides under the lapping water. Home to some of the most prolific kelp forests, Laguna Beach provides a amazing backdrop for capturing photos and videos of this underwater forest.

These waters are a part of the California current traveling from British Columbia down to Baja California before turning back towards Australia. These waters are cool to the human skin and require something more comfortable than a GI-issued sweater for most explorers. Today, divers will sport a 7mm dive suit or a drysuit for comfortable dives as they watch some of the most beautiful ocean life pass before their now manufactured and tempered glass lens. With these opposing currents and changes to tide and weather, it isn't rare to have a wandering visitor from warmer waters arrive. Turtles, whales (passing from Baja to Alaska - like a fairweather traveler), dolphins, porpoises, rays and much more are among the passerby.

In 2010, the third phase of the Marine Life Protection Act Initiative joined the Laguna Beach State Marine Reserve (SMR) and Laguna Beach State Marine Conservation Area (SMCA) to protect approximately 9.7 square miles of oceanfront property. This action created a no-take zone for the entire coastline of Laguna Beach. With no one allowed to fish or take items out of the ocean, the ecosystem of Laguna Beach experienced a major comeback and drastically changed to what we see today as divers. In addition to the kelp forests, we have massive populations of fish, crustaceans and pelagic families coming through all year around. 

In just a few years, Laguna Beach and the surrounding coastlines began to look as they did for Sam on that Memorial Day in 1951. A coastline full of marine life is why a visit to Laguna Beach for any diver, snorkeler or water enthusiast is a must. With specialized equipment and developed safety procedures from the dive legends before us, scuba divers from all over the world can take a dip into our cool, beautiful waters to enjoy a dive or many!

Becoming a better diver!

David Mansfield

This month marks year 22 of my scuba adventures. To toot my own horn for a second; I have accomplished 3,731 actual open water dives as of Saturday  morning (yes, I have a dive log). Additionally, I touched the bottom of a Catalina dive site at 302 feet with the proper equipment and traveled to 28 different countries to experience their waters over these years. Whether it was a cave system in the middle of Missouri or the isolated islands of Micronesia, there's been a commonality on every single dive: I can become a better diver. 

You might think to yourself 'That is impossible! This guy has way too many dives! There is no way he is not just amazing.' - do not worry, in my own mind, I think I'm pretty awesome. But, I would be remiss if I did not accept the fact I have made errors during those thousands of dives. On logbook entry 25, I decided to go on a dive to celebrate my achievement with one of my good friends. As we chatted, I grabbed the new cylinder from my vehicle and set everything up. We got to the water and began our dive. At about 25 feet and 5 minutes, the regulator stopped working completely after a distinct wheezing sound came from my tank. I grabbed my octopus and experienced the same issue. There was no air! In a split second, the realization the cylinder I had put in the vehicle was already used! With my remaining breath and a reddening face, I bolted to the surface and (frantically) orally inflated my BCD. My buddy ascended to address the issue and I began to blame everything but the real problem; I made a serious mistake. I did not adhere to one of the most important principles of scuba diving; the pre-dive safety check. If I would have simply taken the time to run through an inherently safe method of ensuring everything is in good working order, I would have saved myself embarrassment and a possible real issue that could have gone much worse. All these years later, one statement sits firmly in the back of my head: I can become a better diver. 

The word "training" is synonymous with improvement. One does not have to subject themselves to actual emergencies to gain experience where education from more experienced trainers can help. You'll find the real key to becoming good at anything is through consistent and constant practice. The author Malcolm Gladwell deduces a person isn't born with natural gifts. Instead, they are gifted through dedication to hours of honing their craft. Whether it is strumming a guitar or replacing a glass window, the user finds themselves better at that 'gift' through dedication to the craft. If you do play an instrument, you can remember when you first started playing people would walk past you with their hands over their ears and a sympathetic smile. The off-key twangs and erratic bursts of sound were like nails across a chalkboard. With more hours of work, you may now manipulate a musical instrument in such a way people demand to hear you play when you are around. It may come as naturally as breathing to you. The same principles can be applied to your scuba diving. 

Terrible Divers

Having good buoyancy control, breathing techniques and working towards safer scuba diving are worthy goals for a new diver. The divers in the above photo are actually working on hovering, a common goal for all of us when scuba diving. It is easy to look at them and critique the million things wrong in this scenario; but, they are trying to learn how to be a better diver. The truth is they could have honed these skills in a confined water environment and successfully executed them perfectly (and off the poor reef) had the instructor invested in their training and education. That is what those hours in the pool and in safe, sandy environments in the ocean are designed to accomplish. 

As you gain experience in the water, it is also a great idea to seek out further education through a training program. If you want to be better at something, why not practice it in multiple environments that will only make you better at scuba diving! The folks in the picture could be working on base level performance requirements; but, they will become better at buoyancy control if they take the time to do further techniques in a continuing education class or by dedicating their time to performing the skill better. As we all know, practice is an extremely important facet of making ourselves masters at anything. This is where a training program will assist.

When I took the Advanced Open Water Course, I was extremely excited at the experience of night diving. At the time, all Advanced divers were required to conduct Navigation, Deep and Night as three of the five elective dives. These dives were the first dive of the actual specialty course. If you accomplished five of those dives, you'd be certified as an Advanced Open Water Diver. As we descended at Wood's Cove that night, I was super excited. My light illuminated creatures I had yet to see during the day. Lobsters, octopus and rays were flitting about the underwater realm in search of food while the normal day animals were tucking in for their naps. I found the exploration of the reef at night was something I was not fully comfortable with doing. My instructor encouraged me to sign up for the Night Diver specialty. On consecutive nights, we explored other coves and did skills to enhance our comfort level while being in a nighttime environment. This experience motivated me to comfortably dive at night and, at the time, I worked a night job. From that point on, I would spend Saturday and Sunday mornings from 3am to 4am exploring the reef system at Moss Point and more! But, what did I learn? I learned how to become better and much more comfortable operating at nighttime while wearing scuba equipment. Turning the lights off, navigating to and from a point underwater, and much more, taught me how to safely operate in a nighttime environment. Today, we night dive every other Sunday night with the dive club to keep our night diving skills in tip-top shape! 

Seeking out education did not make me a master of the night environment, but it did establish a foundation of principles I could then carry into hundreds of night dives across the world. It made me a better diver. As with all things, I could give you fifteen bullet points on how to become a master. But, my challenge to you is to become better through dedication to the sport of scuba diving. As you get better in the skills you learned in the Open Water Diver program, seek out experience through other courses and conduct dives with more experienced divers. Take the time to read about the latest technologies and techniques. If you can stay dedicated to the craft, you'll find yourself waking up with thousands of dives under your belt, a better education and the ability to teach others the importance of getting better at scuba diving!

An Air Hog's Diary - Improving your air consumption while diving!

David Mansfield1 comment
Diver back rolling into water

It was 1997, the waters off southern Japan were a frigid 52 degrees Fahrenheit; my face hit the cold water and I immediately started the rapid depletion of the precious air in my scuba cylinder. Everyone else was calm and relaxed underwater. I would signal, after 20 minutes, that I was down to 700 psi on my submersible pressure gauge and my dive buddy would look at me bewildered. He showed me his SPG and it still had 2000 psi comfortably sitting in his tank. We slowly ascended to our safety stop and when we got to the surface, the chiding began. "Dude, you are an air hog. Why did you suck down so much air on your dive?!?!?" 

At first, I was embarrassed. How was I the only one in the whole group that couldn't stay down long enough to truly enjoy the dive? What was I doing that they weren't doing? As a competitive individual, I became obsessed with how to properly breath underwater and be the guy that held up my SPG with 2000 psi in it when someone signaled me they were low on air! But, that road included a lot of poor techniques that were risky to my safety and didn't allow me to 'win' the air consumption wars. At first, I would attempt to skip breath on dives. This method would mean breathing in and then basically holding it until the moment I absolutely needed to breath. I then tried other tactics like orally inflating my BCD and strictly using my snorkel on the surface. All these attempts ended with nice headaches and barely an achievable goal when it came to true control of air consumption. 

With each dive, I became better. I honed in on skills and worked hard towards relaxation techniques. Instead of muscling my way through dives and swimming like Dory in Finding Nemo, I found ways to minimize my movement and finally take that 'Air Hog' shirt off my back! Here's some methods to achieving breath control greatness. 

Setting expectations

The first thing is setting realistic goals for yourself when it comes to air consumption. If you are large person, you are naturally predisposed to consuming more air. That doesn't mean you will always perform terribly in the water; it's just science. The oxygen you take in is set to feed your organs, tissues, bones and much more. If there's more product there to serve, you'll require more oxygen than a smaller person would require. If you couple this with experience, you'll find that you can become rather efficient at air consumption and also employ some techniques with your buddies to ensure you enjoy the dive just as much as they do. But, you need not worry, 'bio-prene' is a huge advantage in Southern California waters. You might be an air hog, but you will be a toasty warm air hog compared to your barely able to float friend!

Master breathing

Your body requires oxygen to sustain life. But, lack of oxygen isn't what gives you the urge to breath. It's the build up of carbon dioxide that forces your diaphragm to react. This overwhelming urge to expel carbon dioxide drives your breathing patterns. Which is why skip breathing is not recommended for scuba divers. With the continuous build up of carbon dioxide, a diver might find themselves feeling the need to cycle air at a higher rate. By doing this, we provide further stress to the body and increase the working load while we dive. Therefore, we lose the fight in air consumption by incorrectly breathing in the first place. 

If we remember from our beginning courses, the number one rule in scuba diving is to never, ever hold your breath. By producing full breathing techniques, we actually manage the carbon dioxide build up in our bodies and reduce that urge to breath. Eventually, the action will become autonomous and very similar to the breathing patterns you hold on the surface. Like right now, you are not thinking about breathing in the least bit. Your body is handling the action for you. When we are underwater though, we find ourselves in an environment where it is not natural to breath and the average diver will increase their breaths per minute because of this. A simple action like breathing and exhaling in a controlled, fluid manner will assist in reducing your effort to breathe underwater.

This is something you can practice on the surface as well. Through breathing exercises, you might find yourself able to better control your breathing while diving! 

Diver hovering

Master buoyancy

I've written about mastering buoyancy in scuba diving before. It is a very important aspect of scuba diving and a major contributor to air consumption. If a diver feels like they are constantly in a free fall from improper position of weights or incorrect calculations of air to the BCD, they will find themselves swimming with their hands. This creates work. Work creates breathing. Eventually, a person can tire out from this constant effort and find their air consumed at one of the highest rates. 

Practicing good buoyancy techniques range from correctly finding your position in the water column to correct weighing. All of these techniques will create a relaxed diver in the water. When you couple these with proper breathing, you'll find a diver who is properly consuming their air underwater. When we reduce the use of the BCD as our buoyancy control and increase our capabilities using that internal buoyancy device called your lungs, you will also reduce your mechanical need for air while underwater. Reducing this reliance on the BCD will also contribute to using the air in your cylinder for what it is intended for on a dive; breathing! 

If you were to take one thing away from anything in this article, it would be the understanding that we scuba dive for fun. The intent is to be relaxed, minorly moving, enjoying our activity to the fullest through our technique. If you can relax, you'll find air consumption is drastically reduced.  

Divers in pool

Master finning

An oft overlooked technique is mastering fin control and fin techniques. Typically, there are two types of fin kicks. The scissor kick and the frog kick. A majority of this power is generated from our thighs in both of these kick techniques. With the scissor kick, we find a diver laying flat in the water column with straight, slightly bent knees. This diver is generating power from the hips very similar to a kick from a soccer player. The frog kick technique keeps the legs elevated while generating power from the inner thigh. The key to both of these methods is to move the fins smoothly through the water in order to achieve minimal resistance. When the power of the kick is underway, it will slowly propel us through the water. 

Many divers think they must kick as hard as possible to travel through the water, when the opposite is actually true. As Newton's Third Law states, "for every action, there is an equal and opposite reaction." Therefore, we find the blade of a fin pushing against water and creating propulsion for the diver. By slowing down the rate of this action in an environment where the diver is breathing and conducting themselves in a peak performance buoyancy situation, they'll find that they can move much faster by engaging the right technique. Finning is a learned trait and can be accomplished by taking a specialty class or by practicing on a regular basis. 

Additionally, finning is an excellent way to condition the body for scuba diving. Through the correct fin kick, we'll create a more efficient diver that can breath correctly and glide through the water vice fighting it.

Tank selection

Selecting the correct tank is also imperative for a diver. As previously stated, a larger diver may naturally consume more air. Which means they may just need a larger capacity tank to match the efforts of their buddies underwater. If you are a larger person, you might not want to select an aluminum 63 cubic foot for your diving. This means you'll be shorting the space in your tank for air you breath and shorting the dive even further. Oftentimes, you'll see larger folks with a Steel 100 while their buddies have Aluminum 80's. There's approximately a 21 cubic foot difference between the two tanks and may be the small change that a dive buddy team will find works for those hour long dives in the water. 

Another consideration is the buoyancy characteristics of these tanks. Aluminum tends to lighten up with the reduced psi in the tank while steel has the same buoyancy regardless of its tank pressure. If a diver is attempting to create a perfect buoyancy situation, they may not want to wrestle with their buoyancy at the end of a dive with an emptying aluminum tank. This will create work and walk us right back down the road of consuming that air at a higher rate. 

Whatever the choice of tank, remember that asking a dive professional for help in selection is also important. They can get an idea of your capabilities in the water and determine the right size of tank for you in a given situation. 

Summary

When I was an Open Water Diver in Japan and then Southern California, I found myself often frustrated at having to come up well before the rest of my buddies when we explored our underwater realm. As time has gone on and through honing these techniques, I've become quite the opposite in the water. You can also achieve mastery when it comes to air consumption by working on these techniques both in and out of the water. Take a class to help you master some of these techniques with your local dive shop and, more importantly, get out there and dive! It's the only way you'll become a better scuba diver!
