This is the new updated version of the Sub Alert (also marketed as the Sub-Duck) by Aquatec. This improved safety device has been redesigned and upgraded. Connects in-line between the LP inflator hose and your power inflator. (Works best as an underwater signal device, not as loud above water as the Dive Alert).

Fits most standard power inflators. If you have a non-standard power inflator or Air Link, call for your model.
