The Apeks MTX-R sidemount set is a super tough, rugged, high performance, go anywhere sidemount regulator configuration designed to meet the rigours of cold water and extreme sidemount diving. The MTX-R is highly reliable and also very easy to service out in the field which make it an ideal choice for the expedition and exploration diver.
The MTX-R has excellent cold water performance and has a greatly reduced risk of free flow. This has been achieved by improving several areas, including an innovative endcap and environmental diaphragm, a forged 1st stage body offering maximum thermal preference, a ribbed diaphragm clamp and a redesigned & enlarged heat exchanger on the 2nd stage with metal incorporated into the front cover design.
Recommended for use in 0.5ºC to 50ºC water.
