RB 80

[DRE]

The RB80 doesn't have DIL/O2 - just two supply bottles of bottom mix and off-board gasses that can be plugged in, so no worries about rolling off one tank and just getting O2 in the loop. Basically it's a set of doubles with a gas extender in the middle. Roll offs when contacting an overhead environment are exactly the same as with a regular set of doubles. The RB80 was designed with a very specific goal in mind: cave exploration. DIR is all about bringing the right tools for the right job and that's what the RB80 is all about. As far as its size is concerned, it is bigger than some of the CCR's on the market, but if you're riding a magnum Gavin, towing 2 or 3 more and hauling 5-6 stage bottles (if not more) the size of the RB becomes very relative. There's a very detailed description of the unit on .
