The Dive Alert Plus delivers a loud audible signal both on the surface and under water. Measuring less than three inches square the super-compact Dive Alert Plus ties into your BC’s low-pressure hose via quick-connect fittings. It will quickly get a dive boat’s attention on the surface, or your dive buddy’s attention at depth with just a push of the button. It’s so user-friendly, it received Sport Diver Magazine’s “EDITOR’S PICK” in the 2010 Gear Guide. Click here for more information. Find this product at your local Ideations dealer.
