Review by Billy Snook
Rebreather technology has been around for about a hundred years but it hasn't been until recently that it has become practical for the masses of recreational divers. Bob Hollis & Company have done just that, and they are selling and promoting a truly recreational semi-closed rebreather aptly named the Explorer. The advantages of diving an Explorer are that the diver makes very little noise as compared to conventional open circuit diving, available dive times are much longer (as long as three hours), and you’re breathing warm, moist air instead of the cold, dry air and subsequent dry mouth characteristic of an open circuit system. Not blowing bubbles affords the diver much better marine life encounters and photographic opportunities and is ideal for wreck diving so as to avoid disturbing silt and drastically decreasing visibility.
