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.
Due to production delays and product back-orders, some Hollis products are temporarily unavailable.

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 has led to the development of two new units; Prism 2 and Explorer Sport.

Hollis Explorer Sport Rebreather Breathing Loop

Hollis Explorer Sport Rebreather | Scuba Center is the only Hollis rebreather dealer in Minnesota 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.

Hollis Explorer Features:

  • Scrubber thermal monitoring and optional 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%

  • Simple user interface is easy to learn and easy to dive

  • Automated Pre-dive Setup assures Explorer is prepared for dive

  • Automated Breathing Loop control gives minimal bubbling and hydrostatically controlled buoyancy

  • Bail-out mouthpiece gives a quick one handed operation from closed circuit to open circuit

  • Simple Green or Red primary display

Hollis Explorer Sport Rebreather BOV |Each Explorer rebreather ships with a BOV (Bail Out Valve) installed. BOV is a “Bail-out” mouthpiece which gives a quick one handed operation from closed circuit to open circuit supplied by on-board gas. If the Explorer detects a problem, the diver is alerted in two ways.

First is via the LED “heads up” display which provides unit status throughout the dive, signaling GREEN for normal operation, or RED to bailout. Second, the regulator in your mouth vibrates to tell you to bailout with the BOV if you haven’t already done so.
