DC1 First Stage

  • High performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions.
  • We have just added a 5th low pressure that points directly down from the first stage providing easier hose routing for backmounted doubles, sidemount or even for recreational divers.
  • Swivel turret allows for ideal low pressure hose routing
  • Environmental sealing prevents internal corrosion, contaminants, and icing of the first stage
  • Designed to withstand the rigorous CE standard for coldwater performance
