This Rebreather was introduced at the Boot 1999. The Dräger LAR7 has two supply-tanks and can be switched between Nitrox-SCR- and Oxygen-CCR-Mode on the fly, that means it provides bubble free diving in shallow water and bubble reduced diving in the Nitrox- depth range. The module with the Oxygen-tank, counterlung, scrubber etc. can also be transferred to the divers back. On the right hand side you see the ABLJ's safety-inflation-bottle, a piece of equipment that (in my opinion) no diver should cut out.
