The MTX-R is based on the MTX, a regulator that was developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test. Innovations in design mean that the MTX-R regulator performs in almost freezing water at a depth of over 60 meters, something that very few other regulators on the consumer market can boast.

With an innovative first stage design that helps to prevent ice build up around the diaphragm, the MTX-R is reliable, rugged and expedition ready.

This product qualifies for Free Parts for Life. 

Features: 

• A first of its kind, over-molded first-stage end cap and environmental diaphragm to prevent ice build-up that could cause a free flow in extreme circumstances.
• Forged 1st stage body gives maximum thermal performance.
• Ribbed diaphragm clamp on the 1st stage ensures improved heat exchange in cold water conditions.
• Angled HP ports allow for optimal hose routing and transmitter fitting.
• Parallel turret ports allow for improved hose orientation.
