Hollis DC1 is a high performance, over-balanced first stage, which provides progressively greater imtermediate pressure as depth and gas density increases for superior delivery of gas under the most extreme conditions.
There's an added 5th low pressure port that points directly down from the first stage, providing easier hose routing when diving with back-mounted double tanks or sidemount.
Available with DIN or Yoke -Valve.
