The I-Shad is part of the I-Motion technique. Specially designed with Jackall's state-of-the-art technology, the I-Shad is designed to swim like a baitfish that is not threatened - so bass think its an easy prey. All you have to do is point your rod tip straight towards the water and impart no action - the I-Shad does the rest. A bulge at the end of its tail keeps it stable, and a split tail design creates small vibrations attracting bass to strike. The I-Shad is also injected with two different salt compositions. The top section has less salt than the bottom, making it heavier on the bottom for a more stable swimming action.
