Rebreather Mouthpiece (DSV) with RBSM Headstrap

RB160/RBSM - Rebreather Mouthpiece (DSV or Dive/Surface Valve) with RB Safety Mouthpiece Headstrap

The RB160 is our new and improved Rebreather Mouthpiece with true single-handed lever operation allowing you to switch easily between open and closed. The open position is for normal breathing from the rebreather and the closed position is used to seal the breathing loop, preventing water ingress and buoyancy loss, when removing the mouthpiece.

Key Features:

• True one-handed operation with prominent, easy-to-find raised grips which allow solid leverage between your thumb and fore-finger when moving the lever.
• Operational with either hand.
• Tactile feedback when switching - you can feel (& hear) the positive end-stop when in the fully open or fully closed positions.
• The mouthpiece outlet is offset to the top which lowers the mouthpiece body, increasing the diver's field-of-view and allowing easier access to a camera viewport.
• Sits comfortably in the mouth and is fully compatible with the AP RBSM Headstrap which further increases comfort and security.
• 15% improvement in work-of-breathing compared to the previous mouthpiece design.
• The position of the operating lever is visible to the buddy diver / instructor / dive supervisor.
• Improved design with in-built one-way silicone valves reduces the CO2 deadspace in the chamber.
• Easy Clearing - the size of the water channel has been optimised to allow easy clearing when opening the valve.
• Deep ty-rap channel for secure mouthpiece attachment.
• Robust injection moulded construction with strengthening ribs.
• Moulded in Acetal with PTFE compounded in. The PTFE provides a degree of self-lubrication.

The RBSM - Rebreather Safety Mouthpiece Headstrap

At first you will find using a mouthpiece strap is strange but persevere and by dive 3 you will have mastered it’s use and you will appreciate the benefits.

The RBSM is an added safety feature on the rebreather.

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. Moulded in one piece it is easy to clean and disinfect. The swivel attachments to the flange allow the slap 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 slap strap 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 quickly releasing the strap and for connecting it should you have forgotten to pop the strap over your head while kitting up.
