Adjustable black light holder made of neoprene. - Color: Black - Material: Neoprene - Size: One size fits all - Design: Wrist support - Adjustable: Velcro closure This is a tool for diving while holding a light. I've used it myself, and it works for spearfishing, but it's not suitable for salvage divers. It's easy to drop and lose when getting on a boat, so it's recommended for recreational divers.
