Underwater Tank Banger Noise Maker
Easy to use and safer than banging on your scuba tank with your knife. This easily fits on any tank and can be heard at good distances underwater during your dive! Just pull and let go! the banger (or clanger) will hit the tank with a loud distinctive noise.
Two colours of strap are available: yellow or green to help you tell your dive kit apart when buddying up.
The hose that goes around your tank is made from heavy gauge rubber tubing with great elasticity and ruggedness.
