The Scuba Air Horn uses a small amount of air from your scuba tank to make a loud sound to draw attention to yourself. This small, lightweight pneumatic signaling device uses quick-connect/disconnect hose fittings to become an integrated part of your power inflator and BCD.
No modification is necessary and it will not interfere in any way with the normal operation of your other scuba equipment.
The Scuba Air Horn fits most BC’s with a standard low-pressure inflator attachment. Installation is easy and only takes a moment.
