A simple tool that works extremely well. For fishermen who fish in low light conditions or don’t see as well as they used to, it is indispensable! How to Use: Step 1: Insert the eye of the hook downwards in the notch. It will be held in place by a built-in magnet. Step 2: Insert the line into the groove. Feed the line down the groove and through the eye of the hook. Step 3: Pull the threaded hook off the magnet, and tie with your favorite knot to secure it to your line.
