Dive Alert PLUS v2 Signaling Device Power Whistle Safety System - DV1

The DiveAlert PLUS v2 DV1 adds two pneumatic attention signals to a compatible standard BCD power-inflator connection. At the surface, it produces a piercing air-horn sound to help attract a boat or buddy's attention. Underwater, its internal piston creates a percussive buzzing signal against a stainless-steel diaphragm for nearby diver communication.

The compact device installs inline between the low-pressure inflator hose and the power inflator through quick-connect couplings. Its injection-molded thermoplastic body, stainless-steel diaphragms and chrome-plated brass couplings are built for marine use without batteries or a separate gas source.

• DV1 connector for standard power-inflator configurations
• Separate surface and underwater audible signals
• Pneumatic operation uses the diver's low-pressure air supply
• Quick-connect installation

Safety note: Verify that DV1 matches your exact inflator connection before purchase, and test BCD inflation, deflation, sealing and signaling before every dive. A signaling device supports—but does not replace—gas planning, buddy procedures, visual signals or an emergency plan.
