Apeks - DS4 FIRST STAGE (DIN or Yoke)

This compact first stage is a time-proven workhorse that has been embraced by the technical community around the world.

Key Features:

• 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.
