The Hollis DC7 YOKE First Stage combines an old school design with new technology. The new 500SE utilises a servo controlled valve to provide precision airflow and unparalleled performance for both air and trimix divers in a side exhaust configuration.
- 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
- Fixed hose routing ideal for both backmount and sidemount configuration
- Environmental sealing prevents internal corrosion, contaminants, and icing of the first stage
- Designed to withstand the rigorous CE standard for cold-water performance
- Nitrox compatible to 40% DIN / 300 Bar
