So this XS Scuba safety tube is seriously essential for divers! At 6 feet long (1.83 meters) with a 9-inch circumference, this bright orange surface marker buoy makes you highly visible when you're on the surface. Made from durable urethane-coated nylon with stainless steel grommets, it can handle tough marine conditions. It rolls up super compact into its included mesh bag that measures just 5x3 inches - small enough to fit in your BCD pocket or clip to your gear. When you need to deploy it, just open the bag, inflate it orally using the easy valve, and clip it to your gear. There's even a stainless-steel grommet at the top for attaching a light during night or low-light dives. Surface marker buoys are pretty much required equipment these days for safety - they help boats see you, mark your position, and can signal for assistance if needed. The bright orange color stands out against water perfectly. Seriously, if you're a diver and don't already carry an SMB, this is one of those safety items that's absolutely worth having. It could literally be a lifesaver in certain situations.
