Dr. Slick zingers live up to the standards of the Dr. Slick name. These are quality tools that get used multiple times during any day on the water. Each zinger/reel is made with a 16-inch plastic coated braided steel wire for much better durability than nylon cord zingers. The retractor spring is strong and doesn't wear out. The pin-on model is Dr. Slick's choice for a zinger that will be permantly attached to a vest, pack or boat. On the end is a figure eight clip which easily attaches your tool of choice. For smaller tools like line nippers, you can also take the figure eight clip off and just use the small split ring that attaches it to connect your nippers directly to that.
