XTX technology is also available in an oxygen model. This regulator is built for oxygen percentages between 0 – 100%. This compatibility coupled with its excellent reliability make it the choice for technical divers doing high O2 percentage deco stops.
Green and yellow cosmetic pieces clearly identify that this regulator is dedicated for high-percentage oxygen use.
The compact DS4 first stage has four medium-pressure ports and one high-pressure port (it does not feature the rotating turret found on the DST first stage).
Features an innovative Diver Changeable Exhaust system (DCE). This system gives the diver the ability to change from a small exhaust tee to a large exhaust tee. This gives the user a choice, wider exhaust tee for minimal bubble interference (essential for underwater photography) and narrow exhaust tee for a smaller compact comfortable regulator. Only the narrow exhaust tee is supplied with the regulator.
Can be converted from a right-handed hose configuration to a left-handed one. The process of changing the regulator to a left-handed configuration is both quick and simple. However, this procedure must ONLY be performed by an APEKS Authorised Service Technician.
Available in yoke or DIN configuration.
A braided flexi-hose comes standard. These hoses are lighter weight, more flexible and more durable.
Suitable for coldwater use (below 10 C / 50 F).
This regulator is suitable for use with up to 100% oxygen.
