The Hollis Explorer is a true recreational Rebreather. The unit is neither a fully closed circuit Rebreather nor a pure semi-closed system, but an intelligent hybrid that utilizes the best of both worlds. Its compact, lightweight and extremely easy to use.

The Explorer's patent pending design is unique in using a single gas; Nitrox, and is electronically controlled to achieve an optimal balance of PPO2 and dive time. Plug and Play absorbent cartridges, easy guided setup with go or no go, optional CO2 tracking, and 2 hour duration make this a dream for any recreational diver.

The Explorer diver will benefit from breathing warm gas, have lots of bottom time, and since it does not produce any invasive bubbles, see more sea life than ever before.

The Prism2 is a fully closed circuit Rebreather, ideal for exploring open ocean, cave, or wrecks. This unit can be electronically or manually controlled which means you choose how you want the loop PPo2 maintained.

The standard kit includes an electronic secondary control and primary LED displays with a backplate/wing assembly that provides a complete kit ready to dive out of the box. Unit can also be purchased with or without tanks/valves.

The DG02 can be used in two modes; Digital Bottom Timer or Nitrox Dive Computer with Hollis Z+ Algorithm

The Hollis gaseous CO2 sensor is a vital element of the Explorer CO2 filter monitoring system.
