The AP Diving Rebreather Safety Mouthpiece (RBSM) holds the mouthpiece firmly in position allowing for a very relaxed grip on the bite and significantly reducing jaw fatigue on longer dives. The crucial safety benefit is that the RBSM greatly increases the likelihood that the diver will remain on the loop in the event of going unconscious. Correctly fitted, the RBSM will help prevent water aspiration, loop flood and loss of buoyancy – buying time for the situation to be recovered. At first you will find using a mouthpiece strap is unfamiliar but persevere and within a few dives you will have mastered it’s use and appreciate the benefits.

In addition to the AP Diving Inspiration, the mouthpiece fits oversized orifice on most other rebreathers and 3rd party bailout valves. The AP Diving RBSM is recommended by Divesoft for their BOV. The strap provides extra assurance against mouthpiece loss and the flange provides an additional seal. The combination allows you to relax your jaw more, which is of great benefit on longer dives and ensures the mouthpiece bites last longer. Molded in one piece it is easy to clean and disinfect. The swivel attachments to the flange allow the strap to be to located on the nape of the neck rather than on the crown of your head, which ensures the strap does not slide over your head on water entry. The neoprene provides elasticity and being made of neoprene ensures it does not interfere with your silicone mask strap.

The strap is tightened on either side by pulling forwards on the enlarged webbing tabs; pulling forwards being a more natural action and easier action than pulling backwards with your dive suit on. The strap is easily lengthened by pushing either left or right slider buckles backwards. On the right hand side is a quick release buckle which is great for rapidly releasing the strap and for connecting it should you have forgotten to pop the strap over your head while gearing up.
