Innovative design on the head allows this bait to move through cover when other shakey heads just hang up!! Recessed line to that has no restriction so the line moves freely and will not bind up. The hook eye is elevated to keep the eye from hanging up and helps to protect the knot. Screw lock keeps the bait pinned saving time not having to readjust the bait. Sizes available 1/8 oz with 4/0 hook, 3/16 oz with 4/0 hook, 5/16 oz with 5/0 hook, 1/2 oz with 6/0 hook and 3/4 oz with 6/0 hook.
