Jackall designed the B-Crawl Swimmer as a swim jig to fish near brush piles and shallow cover - a method called "bush crawl" by adjusting the ratio of tungsten in the jig head, Jackall engineers were able to enhance the jig's weight while keeping the size of the jig head the same to provide consistent lure action. The flat-sided head shape emphasizes a rolling action while also making the B-crawl easier to skip. Both the v-shaped wire guard and placement of the line tie enable anglers to fish effectively through cover while still providing anglers with increased hookup ratios. The b-crawl swimmer is the perfect swim jig to catch trophy bass in or around cover.
