  • Unique over-balanced, diaphragm design – as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a rate faster than ambient. This results in superior performance at depth.
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
  • The XTX purge buttons are large and easy to operate. A 2-stage progressive purge is used – press the purge on the side for a lower flow rate, useful where more control is required such as filling lift bags etc, then press in the centre for the full effect of the purge, i.e. when regulator clearing etc.

This stage 3 regulator set includes the Apeks XTX50 DST Regulator with a matching XTX50 Octopus for a superb mid level coldwater rated regulator set with swivelling low pressure turret and diver adjustable second stages.

The Apeks XTX Regulator range is Nitrox Compatable up to 40% and come with hoses in all Packages. With improvements in design and material, the Apeks XTX50 Regulator is smaller, lighter, low in profile, has an improved gas flow, finer adjustments and more. It is available with either an A Clamp first stage or a 300 bar DIN fitting. A DIN fitting regulator can be supplied with an optional A Clamp adaptor thereby offering both types of fitting in one regulator. A Pneumatically balanced system, it reduces breathing effort. An Integrated Venturi Control alters breathing resistance to suit individual diver preference. The regulator has a micro adjuster.

The Apeks XTX 50 Octopus is an incredibly reliable balanced second stage designed for use in all conditions with Apeks regulators gaining particular respect for the cold water abilities. It features a fully balanced valve with a reversible quality, allowing the swap of the second stage from right to left for alternative hose routing. Control over the flow of air inside the second stage is supported by a venturi switch, diverting air back towards the diaphragm to help reduce the risks of freeflowing or directing air to the mouthpiece for finest performance.
