The Reel Leash has a lightweight plastic housing which contains a stainless steel spring and spool of webbing with a brass snap hook. Safer than traditional tubular leashes, because when separated from the board, the board will safely fall away from the kiter. This releases the webbing out 10', with enough torque from the spring system to control/eliminate slack - and the board sling shooting back toward the kiter.
Leash webbing stays coiled away in the housing and out of the way. Reel Leash won't drag in the water, wrap around the kiter or board, or get caught between toes or under the feet while moving around on the board.
