Unlike other "automatic" inflators, this product is immune to rain, humidity or wave splashes.
Robust—rated to 60 meters and inflates at the exact second and meter depth selected. Weight—12 ounces.
No expensive or time-consuming rearming elements to change, just replace the cylinder and go.
Accepts any CO2 cylinder, 3/8-inch, or 1/2-inch threads, and it is compatible with any cylinder cap, including tough flat caps.
