Aqua Lung Grip-Lock Tank BuckleThe Grip-Lock is a classic metal tank buckle/band system that’s been upgraded with a two-adjustment strap system: the “macro” adjustment provides three pre-measured settings that fit the diameters of today’s scuba tanks. The “micro” adjustment lets you do any fine-tuning once the BC is mounted on the tank. Also new is a “finger-saver” feature—an intermediate buckle position that allows you to remove your fingers just before the buckle locks down completely. Price: $45 aqualung.com
Cool stuff that won’t burn a hole in your wallet.
