Scuba diving tank protection with a plastic ball attached by a stretchy silicone band with hard plastic ball. Slips over any dive cylinder from 6 inch diameter and up.
Pull and release the ball to create a reverberating ‘clang’ on your tank while underwater
Plastic ball is a high visibility, neon yellow color to assist with quick location at depth
