The current Apeks XTX series second stages are all identical except for cosmetics and one minor feature. Although their price varies, the XTX series second stages are a pneumatically-balanced downstream design with a large ergonomic venturi control lever, can be reconfigured to reverse the side of the hose inlet (left or right), and they all use the same periodic service parts kit. All the Apeks regulator packages are EN250 certified to a depth of {660 fsw | 200 msw} and have identical extreme performance breathing characteristics that make Apeks XTX regulators a popular choice of experienced sport and technical divers worldwide.
