The IST Tank Banger is a simple attention-grabbing device that fits over the top of your cylinder. The ball is positioned to be within easy reach and a loud knocking noise can be created by pulling the ball outwards and releasing. The noise of the plastic ball hitting your cylinder can be heard over a considerable distance and you don't have to worry about deploying and securing it after... it is there, just ready and waiting for you to use it.
30 DAY RETURNS
If you change your mind, it doesn’t fit, or you become inflicted with buyer’s regret - that's OK!
Mike's Dive Store offer an extended returns policy of 30 days - so you can be rest assured if the suit, piece of diving equipment or gift doesn't suit then just send it back and we will either exchange it or offer a full refund less any postage costs. Too easy!
Please note that there are some special order items on our website that will be subject to a 20% re-stocking fee but we will let you know about these items before we special order them so that you are aware of this. If this is the case we can always help with correct sizing so that we minimise the risk of return.
