Keep your line exactly where you left it. The Dive Labs Reel Stop is a simple stainless steel double ring that locks your reel line in place, so it won't unravel while it's clipped to your harness or tucked in a pocket. The rings are sized to grab and work easily with thick gloves, even in cold water or low visibility. Stainless construction stands up to salt and years of hard use. Add one to every spool in your kit.
