Regulator
  

You cannot breathe directly out of a scuba tank because of the high pressure. A regulator reduces pressure to safe a level that can be inhaled by the diver. A diving regulator has two parts: the First Stage reduces the tank pressure and connects it to the Second Stage which contains the mouthpiece for breathing

The XTX50/DS4 is the same as the XTX50 in terms of performance but uses a different first stage. The DS4 first stage lacks the rotating turret found on the XTX50 first stage and offers one HP port. This compact first stage is a time-proven workhorse that has been embraced by the technical community around the world.

This compact first stage has four medium-pressure ports and one high-pressure port.

Features an innovative Diver Changeable Exhaust system (DCE). The 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. The regulator is supplied with both sets of exhaust tees.

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 authorised Service Technician

This model is available with a DIN connection only.

First Stage:
DS4 first stage – no rotating turret.
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.
Second Stage:
Pneumatically-balanced second stage results in smooth, easy breathing.
Easy-to-grip opening effort control knob keeps the diver in control.
A silicone exhaust valve improves the breathing performance of the regulator.
A heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water.
The Comfo-bite mouthpiece virtually eliminates jaw-fatigue.
