Is there really any difference between a jerkbait and a crankbait? Well they do seem quite similar and have very similar traits. When you look at a crankbait and a jerkbait the main difference you will notice is the body shape.
Crankbaits generally are shorter in appearance and a lot stubbier in their body shape. Jerkbaits on the other hand are longer in appearance and are a lot slimmer in body shape than the jerkbait.
Due to the general longer length of the jerkbait these lures tend to have 3 sets of trebles attached to them, whereas the crankbaits usually have a set of two on them. These don’t need 3 sets because of the shorter body size.
As a general rule cranks have wider longer lips than its cousin the jerk. Therefore I use these for the deeper water. Jerks seem to come with lot smaller lips so they don’t dive as deep, I find these better to use in the first 3 ft of water.
