Explorer 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. It’s 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, optional CO2 tracking, and two 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.

The Fun Part

The Rebreather courses will prepare you for a whole new way of diving through covering three primary divisions:

  • Knowledge Development: these sections cover the principles behind rebreather diving. Through this part of the course, you will establish the knowledge you need to master the specific skills needed in the practical applications and the training dives.
  • Practical Applications: this portion of the course covers the hands-on, pre-, and post-dive of recreational rebreather diving. This primarily means setting up, checking, taking down, and maintaining the Hollis Explorer and other equipment, but also includes planning recreational rebreather dives.
  • Training Dives: consisting of six dives, this part of the course takes place in the pool and open water. Under direct supervision of your instructor, you learn, practice, and then integrate the skills required for Hollis Explorer diving.

Along with this, the course will also count towards your Master Scuba Diver rating.
