Hollis Rebreather History:
Bob Hollis had his first rebreather experiences in the mid 60’s. He used Draeger units to allow him to get close to Sea Otters and other marine life in Monterey Bay. In 1970, Hollis made some of the first dives on the Electrolung rebreather using Heliox down to 300 feet in Honduras and Bonaire, filming ship wrecks and deep reefs. In 1990, Bob & Oceanic developed the “Phibian” rebreather, which at the time was the only commercially available unit.
In 2000, Hollis’ parent company American Underwater Products under two separate contracts with the United States Naval Surface Warfare Command, developed and delivered a unit called the “ATUBA” (Advanced Tactical Underwater Breathing Apparatus). This solid back-ground of rebreather technology led to the development of the Prism 2 and Explorer Sport.
The "Basics":
  • As open circuit (SCUBA) divers we rely upon filling our lungs with air from a pressurized gas tank with every inhalation and then exhausting that volume of air into the surrounding water with every exhalation. As we descend deeper the water pressure around us increases and the volume required to fill our lungs increases; in other words, our air supply depletes more quickly the deeper we dive.

  • A rebreather recycles rather than vents the exhaled breath. The exhaled breath passes into a closed loop, where it is pushed through a chemical absorbent (scrubber) to remove the carbon dioxide, and returns through the other side of the loop for the diver to re-breathe, hence the name "closed circuit rebreather" or CCR.

Unit specific training is required for purchase of each unit described here.  Our prices do not include training.  Courses are available at our facility in Eagan, Minnesota or from properly qualified Instructors around the world.

All Rebreather Sales are face to face sales (in-store). Online sales are not authorized on Hollis Rebreathers.

Hollis Explorer Rebreather
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 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 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.
