Where to buy:
The Hollis Prism 2 is a pretty sleek-looking unit, and it has got some serious technical chops to boot. Plus there are a few options for divers, such as choosing between electronic or manual control options and back-mount or front-mount counter lungs. Explore open seas, caves, or wrecks with ease.
Tested by ANSTI at 100 meters, the Prism 2 had the lowest work of breathing of any mixed gas CCR unit. Tanks and valves will need to be purchased separately.
