Mares Magnetic Shaker Acoustic warning device

Revolutionize your underwater communication with the MARES Magnetic Shaker. Unlike constantly rattling shakers, its patented magnetic system holds the internal ball silently in place, allowing you to dive without disturbing marine life. When you need to get your buddy’s attention, a firm shake overcomes the magnet to produce a loud, distinct acoustic signal. This on-demand alert enhances safety and coordination, making it the perfect tool for photographers and divers who value a quiet, stealthy dive. Clips securely to your BCD for easy access.
