Tank Banger

            Tank Banger     This is a great little item that all buddy divers should have.  The tank banger slides over your scuba tank when you need to alert your buddy you just pull it and let it go. It slams into the tank and makes a loud bong.  This version is uses a grip it, slotted, unbreakable ball that provides an easy grip.  These come in assorted colors and sorry but there is no choice of colors.
