All you need to set a depth stop on your main line when float fishing are Prowla Float Stops & Beads. Simply thread your line through one of the wire hoops and slide a Float Stop onto your braid or monofilament. If the diameter of the float swivel or in-line tube slides over or gets stuck on the Float Stop just pop a Bead out of the handle and thread on after the Stop. There are 20 Stops and 6 Beads on each handle. The Stops grip best on breaking strains in excess of 30lb.
