The XTX100 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 XTX100 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).

The XTX100 regulator incorporates a new front cover manufactured using high strength plastic which greatly improves the durability of the most vulnerable part of the demand valve and an aesthetically pleasing chrome plated metal insert immediately identifying this regulator as a top of the range model.

The new ergonomic Venturi lever of the XTX100 has been designed to reduce the amount of grit ingress and also incorporate an index-able, tactile / audible ratchet Venturi lever mechanism.

A new swivel hose connection is available at an extra cost. This allows the demand valve end of the hose connection to rotate and pivot, providing a more comfortable fit.

A new silicone exhaust valve has been used on the XTX100 regulator improving breathing performance.
