Deco Efficiency  Imagine diving for 60 minutes at 100 feet with no decompression time. Or 90 minutes at 65 feet. Or two hours or even four hours at shallower depths. Rebreathers reduce the nitrogen out of the air you breathe, reducing significantly your nitrogen load that leads to decompression diving, longer surface intervals, and, at worst, decompression sickness.

Less to no Bubbles! Your exhaled gas isn't released into the surrounding water. This means you aren't venting bubbles all over the place. Loud bubbles. Clouds of bubbles. Less bubbles means diving silently. That silence, and the lack of scary random bubble clouds, allows you to get eye to eye with shy marine life that would usually hide upon hearing you approach  

Get Closer! Most professional UW photographers are using rebreathers and are able to approach critters without them swimming off as quickly

More Time!  For example, with a Hollis Explorer, you'll carry 3-4 hours of breathing gas for just about any depth (based on the nitrox mix). For Closed circuit units, like the Prism 2, you carry upwards of 6+ hours of brething gas!!! .

A truly SILENT WORLD (Hey that's the name of the store???!!)
