We always need to attach more stuff to our equipment to free up our hands when we need them. Lanyards for lights, cameras, gauges, game bags, or maybe even a fish stringer when spear fishing. Having a few spare Quick Links in your gear bag is a must for the serious diver. Stainless Steel Quick Link has a threaded clasp that assures attachment of whatever you need secured and will release only when unscrewed.
Keeping items clipped to your equipment make you more streamline in the water and prevent items such as gauges from damaging the environment. If corrosion resistant security is what you need the Quick Link is what you want. Quick Link is a great Save-A-Dive kit item. Buy several so you're never caught short handed on a dive.
