The XTX200 regulator incorporates the new feature of the Diver Changeable Exhaust System (DCE). This system gives the diver the ability to change from a small exhaust 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 travel or for use as an octopus regulator). The exhausts are made from strong, yet light-weight material, essential for the diving environment. We also supply different coloured mouthpieces and exhausts for regulator individualisation which is very useful when using multiple regulators with different mixes.

The XTX200 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 purge button has improved the purge itself. Due to the new open design the purge is self clearing and prevents debris build-up.

The new ergonomic Venturi lever of the XTX200 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 XTX200 regulator improving breathing performance.

The graph opposite shows the breathing cycle of the Apeks XTX200 regulator. Performance is calculated by plotting and recording this cycle. The inhalation line begins on the right hand side and runs along the bottom to the left. The first oscillation (termed the cracking spike) represents the effort required to initially open the valve and begin air delivery. Even at this testing depth the graph shows the low Work Of Breathing (WOB), indicating the diver is expending almost no energy in maintaining air flow. The cycle continues and the upper line (left to right) represents the WOB whilst exhaling (greater due to increased gas density at depth). The total WOB is calculated by measuring the total area within the loop - an incredible 0.41 Joules per Litre.
