Spinner bait are good for attracting and catching bass when fishing. In order to have the lure and the bait working correctly when using this type of bait, you will have to attach the bait directly to the lure. This can be done using the improved fisherman knot. After threading the line through the bait, you should leave about 6-8 inches of line to tie the knot. Begin by making about 5 twists around the line and then thread the line through the hole created below the twists. After threading this through, thread the line through the hole which is formed subsequently. By tying this knot, you have not attached your spinner bait successfully and should be able to test this out on your next fishing trip.
