ABV-2 with Visor for Full Face Mask for use with AGA or Guardian FFM

The OTS ABV-2 Ambient Breathing Valve allows divers to breathe ambient air while remaining fully suited up on the surface, helping conserve valuable cylinder gas before entering the water. This ready-to-install assembly includes the ABV-2 pre-installed on a Guardian Full Face Mask visor, making installation quick and straightforward.

Operating the valve is simple. While on the surface, rotate the valve counterclockwise to open it. Fresh ambient air flows through the one-way valve, across the visor to help reduce fogging, and into the oral-nasal cavity. Exhaled air is routed through the second-stage regulator, helping prevent carbon dioxide buildup inside the mask.

When it's time to dive, rotate the valve closed and begin your descent. Even if the valve is accidentally left open, the increased pressure inside the mask during descent helps force the valve closed, while the valve disc provides additional protection against water intrusion.

The compact, low-profile design stays out of the way when closed, making it an excellent upgrade for divers who spend extended periods on the surface before entering the water.
