Mares EOS Strobe
A small magnetic shaker that serves as an underwater signaling device. Perfect for every diving trip. After shaking, it emits an audible signal, perfectly audible under water. Thanks to it, you will quickly attract the attention of your partner, warn him or alert him to help. It has a strong rope for attaching in a convenient place and a magnet plug that blocks the sound of the shaker when it is not needed.
