The accessory / reel mount, as the name implies, was designed for quick and easy attachment of reels and other accessories to a speargun. This mount is located in front of the handle and is standard on all Reaper, Explorer, Elite, Euro, Mid Handle, and Woody Magnum spearguns. Adapter mounts are also available to retro fit older and non JBL models. To mount an item, line the accessory up with the rear narrow end of the mount and slide forward until firmly seated on mount. Tug accessory toward muzzle to confirm that it is seated securely. The friction between the accessory and mount will keep it in place. Any forward pressure the accessory may encounter will not unseat accessory and be met with resistance from the mount. We recommend that when using a reel, the shooting line be run through the stainless eyelet on the bottom of the muzzle (if available).
