The G Divers Surface Air Valve (SAV) allows the user to breathe ambient air at the surface, conserving tank or surface supply air. It is simple to use and its low profile keeps it out-of-the-way.
The SAV is designed to conserve the diver's air while on the surface. This is NOT a snorkel. Generally, when diving with a full face mask, the diver is breathing off of a scuba bottle or surface supplied air. With the SAV, the diver is able to breathe ambient air without removing his/her FFM. Operating the SAV is simple. If you rotate the valve counterclockwise, you will breathe ambient air. If you have the valve rotated fully clockwise, it will be closed and you will breathe off of your supply air. Surface Air Valve is covered by a 24 month limited warranty.
