The XTX20 warm water regulator can be converted from a right handed hose configuration (as supplied from the APEKS factory in the standard) to a left handed one. This feature is known as the Reversible Venturi System (RVS). Changing the regulator to a left handed configuration is both quick and simple and can be performed by any APEKS Authorised Service Technician.

The XTX20 regulator incorporates the new feature of Diver Changeable Exhausts 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 of the wider exhaust tee for minimal bubble interference (essential for underwater photography) and the narrow exhaust tee for a smaller compact comfortable regulator (ideal for use as an octopus regulator).
