State of the Art Rebreather
FRONT MOUNTED COUNTERLUNGS
Dual, front mounted counterlungs provide the diver with a flexible reservoir equivalent to the maximum displacement of the diver’s own lung volume and ensures the lowest possible hydrostatic loading.
These counter lungs are fitted with both automatic and manual gas addition systems and a variable volume control valve (used upon ascent to vent excess expanding gas volume or to purge the loop). Diluent addition is automatically achieved as hydrostatic pressure increases and the counter lung collapses against the valve actuator.
BACK MOUNTED COUNTERLUNGS
Backmounted Counterlung positions lungs behind the diver leaving the chest free for attachment of additional tanks and accessories. This also allows improved streamlining with less drag and better horizontal trim.
Features a 2 piece bag design for improved WOB performance and easy removal of the internal lung for cleaning or replacement. ADV Upstream Valve design is reliable and resistant to free flow which is a benefit for the addition of valuable diluent gas. All gas delivery systems on the Prism 2 have both automatic and manual function. Water Trapping T-pieces keep excess water from the breathing loop inside the counterlung for easy draining. Streamlined Hose Fittings keep LP hoses routed inside closest to the diver which avoids overhead interference. Machined DIL and O2 MAV controls ensure a rugged and reliable design, also allowing offboard gas plugin on both sides.
REAR MOUNTED RADIAL SCRUBBER
The Prism 2 utilizes a user packed, radial 5.5lb CO2 scrubber, which features the best possible duration, insulation and work of breathing on the rebreather. The scrubber canister is mounted vertically on the backplate and between twin supply cylinders (one each, oxygen and diluent). The clear scrubber bucket is molded from Engineered Thermoplastic. This Hollis exclusive design ensures the CO2 scrubber is installed, packed and provides a visual for positive loop integrity.
HIGH PERFORMANCE
DSV AND BOV
Every Prism 2 ships complete with a DSV (Dive Surface Valve) standard and BOV (Bailout Valve) as an available option. The BOV features a high performance regulator valve, is incredibly lightweight and is a direct bolt on for your Prism 2 to replace the DSV. The Prism 2 BOV is considered a basic safety device for the rebreather by many professionals and meets the requirements for training in Technical rebreather courses.
ELECTRONICS
The electronics, sensors and batteries are mounted in the electronics head assembly at the top of the scrubber, with supply hoses feeding over the diver’s shoulders into the top of the counter lungs. An analog LED primary display offers a quick reference of unit performance with status and alarm indicators while an independent digital OLED secondary display verifies the unit’s performance.
