The Sharkskin High Visibility Buddy Marker is perfect for all underwater activities – scuba diving, snorkelling or spearfishing. Attached it to yourself, your equipment or your buddy to ensure you are visible to others on your underwater adventures! The battery compartment is sealed and battery does not need replacing so there is no risk of flooding and no need to change the batteries for the life of the light.

I really like how it turns itself when in water and turns off out of water. The clip allows to connect it various locations on gear. My buddy said the is quite visible under water.
