Information courtesy of Dave Harrison, the creator of JB Signature Lures:
"The JB Signature Lures Dive Bomber is a heavily keel weighted 'Swim bait bullet'. With a slim profit and an offset hole, it zips along under the surface with an enticing action that looks very realistic in the water. The asymmetrical shape and keel weighting ensures they always run true at trolling speeds 7-10 knots in all conditions and up to 15 knots on those calm days.
The Dive Bomber was originally designed as an easy running lure for the shotgun (stinger) position that doesn't blow out and cross over other lures when the weather gets a bit sporty. It runs great in all positions, however, and looks really fishy running on the long rigger in clean water.
Like all JB Signature Lures, the Dive Bomber has an enlarged hole at the back of the head which acts as a hook lock. Just wrap some tape around the crimp and pull it into the hole to set the hook."
This particular head is the Medium size with 9" skirt saddles. The color scheme comes in a "Mackerel" pattern with a dark green/gold/silver head with black mackerel stripes along the back. The entire lure head has a beautiful rainbow-iridescent hue to it - Photos cannot do any of these lures justice. Skirted in flashabou with gold-green and black stripes/white pearl over green-blue and ice blue. Flashabou skirting was done by Dave Harrison himself.
