Regulator MTX-R SIDEMOUNT SET

The APEKS MTX-R Sidemount Set is a technical scuba regulator designed for cold water diving and advanced sidemount configurations. This scuba regulator set offers superior performance at depth thanks to its unique overbalanced diaphragm design, which allows the average pressure to increase faster than ambient pressure as the diver descends. The forged first stage, with ribs for maximum heat exchange, and the over-moulded endcap seal system provide excellent freeze protection in cold water conditions (below 10°C). EN250A certified for use with Octopus in cold water, the MTX-R is a professional diving equipment ideal for technical diving, wreck diving and cave diving.
