The MTX-R is not only a reliable regulator, but it’s always ready when you are. The perfect choice for the explorer.

Military Grade Performance- Now in Sidemount Configuration

The MTX-R is extremely reliable. Several areas of the regulator have been reinvented and improved to reduce risk of free flow in extreme cold water environments. The addition of an innovative endcap and the unique over-balanced diaphragm design have allowed the diver to go deeper in colder temperatures.It is only of the only regulators on the consumer market that can perform in near-freezing water at depths of over 190 feet. The first stage is specifically designed to prevent ice build up, effectively prevent free flow. It meets all aspects of the NEDU (Navy Experimental Dive Unit) military requirements. The MTX-R is dependable and always ready to go. Sidemount configuration is essential to the weathered and experienced diver.

Legendary First Stage Capability

The MTX-R Sidemount System features a groundbreaking over-moulded first-stage end cap to the environmentally sealed diaphragm, which prevents ice build-up that could cause free flow in extreme circumstances. The end cap also eliminates maintenance issues associated with silicone, oil, or grease filling. The heat exchanging ribs on the first stage provides maximum thermal performance. The diaphragm clamp is also ribbed in order to improve heat exchange in cold water conditions. Not only is the first stage overbalanced for superior cold water performance, but it also features a double swivel hose, is designed to be protected from impact damage, and has angled HP ports for optimal house routing and for fitting transmitters. The MTX-R was born for cold water adventures.

Redesigned Second Stages

The MTX-R features a reversible (right and left hand) second stage that has been redesigned and enlarged to include an all-new patented heat exchanger. This feature surrounds the valve mechanism which in turn dissipated the cold caused by gas expansion. The second stages are also protected by large elastomer bumpers on both the sides and the top. This allows for the regulator to withstand the bumps and bruises that come with long, arduous expeditions. The MTX-R second stages come with Apeks’ comfo-bite mouthpiece, to reduce jaw tension over long periods of time, giving you added comfort.

Diver Changeable Exhaust System (DCE)

The MTX-R, along with other top Apeks regulators, includes an innovative diver changeable exhaust system (DCE). This all-new system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. Both exhaust tees are included with the regulator. The larger exhaust tee is perfect for photography as it provides minimal bubble interference. The smaller exhaust tee is more compact and is therefore more comfortable. The regulator can be converted from a right-hand configuration to a left-hand configuration by a technician. It’s suitable for cold-water use (below 10°C). It’s compatible with EAN 40 when new. It has an over-balanced first stage for superior performance at greater depths. An environmental dry system keeps water out of the main spring chamber of the first stage, which prevents ice buildup and contamination.
