The shaker utilizes a unique magnetic system, featuring magnets located inside on either end, with a ball bearing positioned in between. When the device is shaken, the movement of the ball bearing generates a loud echo sound underwater, making it an excellent tool for underwater communication. This innovative device also serves as a valuable underwater safety accessory, ensuring that divers can effectively signal each other in various situations.
