Before the XTX range of regulators came along, the ATX models ruled the seas. The ATX is still available today and offers a fully balanced first and second stage with cold water capability (can be used in all temperatures including those below 10 C / 50 F). This high-performance regulator boasts an over-balanced first stage coupled with a pneumatically balanced second stage. The smooth, quiet breath is sure to enhance your diving enjoyment. Suitable for coldwater use thanks to its first stage environmental dry seal and second stage heat exchanger. Compatible with EAN40 out of the box.

This innovative, low profile design minimizes drag. The pneumatically balanced valve provides superior performance for an alternate air source, making it a perfect complement to the high performing Apeks regulators. Unique 120˚ angle between the mouthpiece and the hose, which is ideal for sharing air with your buddy. Large purge – easy to use either way up. Can be routed over either shoulder. Low profile ensures less drag in water and keeps it close to the body out of the way. Bright colours ensure visibility in panic situations. Breathes smoothly when positioned right side up or upside down. High visibility 36” yellow hose distinguishes your Egress hose from your primary hose and is easily spotted in the event of an out-of-air emergency. If used with an unsealed first stage then it is only recommended for warm waters, but is suitable for cold water diving when used with any Apeks environmentally sealed first stage.

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. 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. 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.

The perfect octopus to complement your MTX-R regulator. Yellow highlights for visibility in an emergency Protective bumpers to protect the second stage from impacts and scratches in the most vulnerable places. Large purge button. Reversible second stage for either a left or right hand gas supply configuration. A heat exchanger (patented) dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water for a more comfortable breathe.
