The famous sound recorder that has helped thousands of underdogs in difficulty. It is driven by the air coming from the Jacket whip. It works on the surface by launching a very acute of about 130 decibels.

Traditionally, scuba divers have relied on whistles as their only signaling device in surfacing emergencies. But if a diver is disabled and can't blow into the whistle, the whistle makes no sound at all. Equally frustrating (and dangerous), if a diver needs to attract the attention of someone who is too far away to hear the whistle, the whistle is of no help. In contrast, Dive Alert enables divers, at the mere touch of a button, to generate a blast of sound that can be heard up to a mile away!

Dive Alert is a specially designed, small, lightweight air horn that fits between your BC's power inflator and its air hose to become an integrated part of your power inflator. Installation is easy and takes only a moment. Dive Alert does not require any modification of your other equipment, and it does not interfere in any way with its normal operation. When you need to get someone's attention on the water's surface, you simply press a button and Dive Alert uses a small amount of air from your scuba tank to make a piercingly 132db loud sound; even as little as 100psi will give you a full-throated screech. DA1 fits All Standard Inflators.
