This is an amazing tool for any fisherman or survivalist. The Yo-Yo contains 20 feet of 60lb coiled line with a snap swivel on the end of the line. Attach a hook, a small piece of lead shot, tighten the line, engage the wire trigger and your ready for action. The Yo-Yo does the rest. As the fish takes the bait, it trips the trigger, and automatically sets the hook. The Yo-Yo can be attached to limbs, boat docks, the side of a boat, or any other means that will suspend the reel a couple of inches above the water. The YoYo also makes an excellent device for ice fishing.
