The RK3 HD is the next fin in the RK3 range of fins. The RK3 HD is made from a higher density material than the standard RK3, which makes the fin stiffer and heavier. The RK3 HD was developed in response to feedback from divers who prefer a heavier fin. The new compound of the RK3 HD adds weight to make it more negatively buoyant than the standard RK3.

An ideal fin for dry suit diving.

Features: 

  • Based on one of the first vented rubber fins sold in North America and popular among military and professional divers.
  • Compact, and ultra-rugged for use in harsh environments.
  • Improved foot pocket with spring straps for ease of use with cold hands or thick gloves.
  • The design has been the standard gear issue fin for military, special ops, coast guard and public safety divers for decades.
  • Short wide blade provides maximum forward thrust while maintaining great maneuverability.
  • Vented blade design reduces resistance on the upstroke and enhances thrust on the downstroke.
  • The vents also eliminate vortexes that can occur along the back of the blade much in the same way split fins eliminate the vortex.
  • The blade material designed to hold up in the toughest environments, temperatures and abuse.
  • Two large grommet holes designed to fit most karabiners for easy storage of the fins while accessing the dive site.
  • Spring straps as standard.
  • Custom designed buckle holds spring straps in optimum position.
  • Available in black, grey and orange.
