It keeps the bait suspended off the bottom while the sinker knocks around along the seabed, enticing a bite. The sinker sits right on top of the hook when casting.
The knocker rig works best when fishing for species that hold tight to structures like reefs, piers, pilings, oil rigs, shipwrecks, rocks, etc.
The knocker rig is simple to tie, even for beginner anglers. All you need is a circle hook, egg sinker, barrel swivel, and at least five feet of abrasion-resistant leader line.
Monofilament is the best type of leader for the knocker rig. It offers good abrasion resistance since you’ll be throwing your bait around jagged structures.
Select a swivel with a slightly heavier test rating than the leader you’re using. Tie the swivel to your main line using a swivel knot.
