Dive Alert Plus V2 Signaling Device — DV1 Version 2 Pneumatic Inflator Attachment with Chrome Quick-Connect and Loud Long-Range Signal

Dive Alert Plus Version 2 (DV1) is a compact, lightweight pneumatic signaling device that connects to standard power inflators to produce an extremely loud audible alert on the surface or underwater.

If you want a simple, reliable way to call attention while diving or at the surface, the Dive Alert Plus V2 integrates directly with your BC power inflator using quick-connect chrome-plated brass couplings. It draws only a small amount of tank air to deliver a sharp, far-reaching tone; divers have reported the sound being audible up to a mile away in favorable conditions. Installation takes moments and requires no tools, making it a practical addition for recreational and professional divers who want a dependable signaling option.

How does the Dive Alert Plus V2 attach to my buoyancy control device?

Installation is designed to be fast and tool-free: the device connects inline with your inflator hose using the included chrome-plated brass quick-connect/disconnect couplings. The secure fittings are corrosion-resistant and compatible with all standard inflators, making the unit easy to add or remove when needed.

• Chrome-plated brass quick-connect and disconnect couplings for durability
• Inline installation connects directly to standard inflator hoses
• No tools required—attach or detach in seconds
• Designed for compatibility with common BC inflator fittings

What kind of sound does it make and how far can it be heard?

The Dive Alert Plus V2 releases a high-pressure burst of air that generates a piercing, attention-grabbing tone both on the surface and under water. The acoustic design focuses the energy so the sound projects well; anecdotal reports indicate it can be heard at very long distances under ideal conditions, providing a clear way to attract attention.

• Pneumatically driven — uses tank air for a loud, penetrating tone
• Effective on surface and underwater for versatile signaling
• Engineered to produce a concentrated, high-decibel sound
• Minimal air consumption preserves primary gas supply

Will using it waste my tank air or affect my buoyancy control?

The device is designed to use only a small amount of air from your tank with each activation, so it won’t meaningfully deplete breathing gas or interfere with normal buoyancy management. Because it attaches to the inflator circuit, it operates independently of your regulator demand while remaining safe to use during surface or in-water signaling.

• Low-volume air usage per activation to conserve tank gas
• Connects to the inflator circuit—no change to regulator function
• Quick bursts recommended rather than continuous use
• Designed for safe operation while diving or on the surface

How rugged and serviceable is the Dive Alert Plus V2?

Built with chrome-plated brass couplings and a compact housing, the unit is made to withstand marine environments and routine dive use. The simple mechanical design reduces potential failure points, and the quick-disconnect fittings make inspection, maintenance, or replacement straightforward.

• Chrome-plated brass hardware resists corrosion
• Compact, lightweight construction for minimal drag and bulk
• Simple mechanical operation with few moving parts
• Easy to clean, inspect, and reinstall between dives

Who this product is for: Dive Alert Plus V2 is suited to recreational and professional divers, instructors, dive guides, and anyone who wants a reliable, compact signaling option integrated with their BC inflator. It’s especially useful for divers operating in busy water, on drift dives, or on remote sites where attracting attention quickly is important. If you value simple installation, minimal maintenance, and a loud pneumatic signal without needing extra batteries or electronics, this accessory is a practical safety add-on for your diving kit.
