More on Snap Hook
Snap hooks, including bolt snaps and trigger snaps, are used in diving to attach accessories like lights, reels, or spools to BCDs or harnesses. Bolt snaps are favored for their reliability and ease of use with gloves. They come in stainless steel or brass and should be rinsed after use to avoid corrosion. Technical divers standardize clip orientation and placement for consistent, intuitive gear retrieval even in low visibility.
