Mantis full
face mask has a new product!
A Surface Breathing Valve. This device allows you to breathe
on the surface saving your scuba bottle air for the dive. This
is similar to our ABV* Ambient Breathing Valve.
*ABV is a registered trade mark.
Above is a picture of the Surface Valve installed
in a Mantis FFM and in the Open position. This allows the user
to be on the surface with the FFM on and breathe surface air.
The above picture is the Surface Valve in the closed
position. You simply depress and lock the cover down to secure
the Valve.
