I hope these bastards go deep. That frog breathing equipment can be deadly at depth... Pure oxygen. I never realized you could actually buy this stuff on the market..

Not is you use NitrOx. Allows you to dive at depths deeper than recreational diving.

Rebreathers are becoming very popular with recreational divers. Underwater photographers especially like them because there are no bubbles as with normal scuba. This equipment is readily available but it does not deliver pure oxygen. Breathing pure oxygen at depths greater than 30 feet will kill you.

Re-breathers are picking up popularity in the sport diving world. Great stuff when they work...and, if everything is working, much safer at depth.

Cool $5K Rebreathers

PURE oxygen! Bwahha haaa haaa...

The scuba gear is a rebreather system....has barely any escaping bubbles...since the air is reclycled, scrubber and rebreathed...hence the name REBREATHER. No bubbles escaping to the surface...hard to detect...also stay down a long time too...

Sounds like an easy way to make a stealthy approach to a nuclear power plant

to E&E (escape and evade) after firing a heat seeking MANPADS missile at a departing passenger or commercial jet.
