A 12″ stainless steel scuba pointer stick. Brand new and never used.
As a pointer : The diving stick, as its name suggests, is primarily used by divers, instructors, and divemasters to point out marine life or interesting coral to their diving group without getting too close or touching the creatures.
As a muck stick : When diving in sandy or silty sites, such as the ocean bed or lake bed, the scuba pointer stick is a great way to avoid disturbing the bed, causing the sand or silt to rise, which in turn reduces visibility.
As a tank banger: Communicating underwater can be a very difficult task, especially if you’re diving with a group. Tank bangers consist of a plastic ball attached to an elastic band and is strapped over one’s scuba tank. To grab the attention of someone in the diving group, pull the ball back and allow it to hit the tank. A dive pointer stick can be used as an alternative to a tank banger. Hitting your diver’s tank with this can create a clang loud enough to be heard.
