Scuba diving accessory
Ideal for getting attention underwater
Mares Magnetic Shaker
The Mares magnetic shaker features a special magnetic system which makes it the ideal tool for getting heard only when you need. The ball bearing inside will remain on the magnet until shaken loose, creating echoing sound waves.
Greatly useful in getting someone's attention when you desire whilst preventing any unnecessary rattling when moving around or entering the water. This can be connected to your BCD via a D-ring, or you can keep this in your pocket as it is small enough to fit in.
