The Hollis Surface Marker Buoy (SMB) has a self sealing opening to prevent gas escaping and the buoy from deflating on the surface.
An over-pressurisation valve allows excess gas to be vented automatically to prevent damage and also allows the diver to manually deflate the SMB.
A hose / oral inflator attachment allows the SMB to be inflated via a quick disconnect hose or manually inflated if required.
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.
