Rating: A must for the G Diver Mask
Reviewer: Tony Shih, - View all my reviews
Excellent option to have. Very simple to install and use. Will allow the use of ambient air above surface. A simple twist to close before diving down.

You can use the mask without this cap.But you save a lot air the suface with it open. I did two dives with it open and still my face did not flood
