DiveAlertPLUS is a specially designed, small, light weight pneumatic signaling device that uses quick-connect/disconnect hose couplings to become an integrated part of your power inflator. Installation is easy and takes only a moment. 

DiveAlertPLUS uses a small amount of air from your SCUBA tank to make a piercingly loud sound in air or water. People have been able to hear a DiveAlertPLUS one mile away from a diver in need above water. In conditions where visibility is limited, a DiveAlertPLUS can be a life saver. Underwater you can sound for attention quickly with a squeeze of the device. 

Maintenance

After each use, DiveAlertPLUS should be rinsed with fresh water. This is especially important after use in chlorinated swimming pools and in other water having corrosive substances. Additionally, it is highly recommended that you blow the water out of DiveAlertPLUS before storing. This can be done by pressurizing and activating both the surface and subsurface signaling elements. We recommend that you cup your hand over the surface signaling element to muffle the loud noise.

NO MODS REQUIRED

DiveAlertPLUS does not require any modification to your equipment, and it does not interfere with the normal operation of your equipment. The DiveAlertPLUS comes in three different models to accommodate different connectors: DV1, DV2, and DV3.

EASY TO USE DESIGN

Once the tank is turned on and the DiveAlertPLUS connected, squeeze the DiveAlertPLUS softly underwater for a subsurface signal. Or squeeze it firmly on the surface for a loud surface signal blast. Check that DiveAlertPLUS is installed correctly and functioning properly before every dive. Also be careful not to point DiveAlertPLUS toward yourself or toward anyone who is in close proximity to you when you activate the surface signal (it’s really loud!).

HOW IT WORKS

The DiveAlertPLUS uses chrome-plated brass couplings to attach to your power inflator. Squeezing the device engages the actuator valve stem causing a small amount of air to flutter a stainless steel diaphragm, emitting a piercingly loud sound from the injection-molded thermoplastic body. The subsurface / underwater signal is produced by a percussion "buzzing" noise made by a piston hitting a stainless steel diaphragm much like a drum.
