Rebreathers may sound like science fiction to many divers, but the concept has been used by divers for many decades before modern scuba diving was invented. By using carbon dioxide scrubbers and oxygen, rebreathers recycle exhaled air into breathable gas that translates into longer dive times and deeper depths. What divers really love about rebreathers, however, is diving bubble-free. For photographers, being able to move silently makes a tremendous difference when approaching skittish wildlife that would otherwise scatter the moment a scuba diver exhales. For military applications, the advantage of moving without bubbles is obvious. Recreational divers can enjoy a more serene, tranquil experience, to feel more attuned with life in the ocean.
Rebreathers have become more streamlined and much safer, opening up the sport to more people. With Hollis's recreation centered rebreather designs, getting into rebreathers has never been easier.
