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 metres, something that very few other regulators on the consumer market can boast.

• A first of its kind, over-moulded 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.
• Superb protection from impact damage on both the 1st and 2nd stage.
• Simple to use 2nd stage with no dive adjustment controls and a reduced chance of free flow.
• Double swivel hose for greater freedom of movement and comfort.
• Patented heat exchanger surrounds the valve mechanism, dissipating the cold caused by gas expansion while drawing in the warmth of the ambient water.
• Developed in accordance with the United States Navy Experimental Dive Unit extreme cold water test.
• Tested for Octopus use to 60 metres in cold water.
