Green and yellow cosmetic pieces clearly identify that this regulator is dedicated for high-percentage oxygen use.

The compact DS4 first stage has four medium-pressure ports and one high-pressure port (it does not feature the rotating turret found on the DST first stage).

This 1st Stage is suitable for use with up to 100% oxygen.

This comes as M26 as standard.

First Stage:

  • DS4 first stage.
  • 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.
  • 2 HP ports and 4 MP ports are angled for optimum hose routing.
  • An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out.
