Green and yellow cosmetic pieces clearly identify that this regulator is dedicated for high-percentage oxygen use.

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 compact exhaust tee is supplied.

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 Authorized Service Technician.

A braided flexi-hose comes standard. These hoses are lighter weight, more flexible and more durable Suitable for coldwater use

This regulator is suitable for use with up to 100% oxygen.
