JJ-CCR Rebreathers have just launched a new safety device the RBSM. For those who already have the JJ and are patented, you can request it for free (1 per diver, only paying for shipping). Mouthpiece is included with the strap.
For those that want a second one or for those divers that want to purchase one for a different rebreather, this is the item to add to cart.
The RBSM head strap can be fitted to the DSV assembly which offers additional support by holding the mouthpiece towards the wearer. The strap is particularly useful on long duration dives by minimizing the effort needed to retain the mouthpiece in position, thereby reducing jaw fatigue. A head strap may also help retain the position of the mouthpiece if the diver becomes unconscious.
