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 Hollis Explorer 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, CO2 tracking, and 2 hour design duration make this a must 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.

  • Scrubber thermal monitoring and CO2 sensing assures good gas in the breathing loop
  • PPO2 intelligently controlled for a proper balance of PP02 and bottom time
  • Automated dive data logging
  • Back mounted counterlungs with streamlined cover to offer good protection
  • Modular component design makes it easy to setup and clean
Nitrox Electronically Controlled Hybrid - uses readily available Nitrox in 32-40%
