The Scubapro Tank Banger Tank Accessory provides a simple underwater signaling option for scuba and recreational diving. This lightweight device, weighing about 0.1 lb, attaches to a tank and produces an audible clang to help you communicate with your dive buddy underwater. A simplified underwater noise-making solution, it is designed to be unobtrusive while you focus on your dive.

The elastic band, made of surgical tubing, is fitted with a hard plastic ball. Stretch the band over your scuba tank to secure the signaling device and keep it within easy reach during dives.

To get your buddy's attention, reach back, grab hold of the ball, pull it away from the tank, and let it go. The clang is audible underwater, providing a practical signaling option without adding complexity to your diving gear.

Compact and recreational by design, this tank accessory adds a straightforward signaling capability to your scuba gear, supporting clear communication during underwater adventures.
