The shallow invader is a hybrid crank bait. The front half is hard plastic and the back half is a soft plastic replaceable tail. This construction gives the shallow invader a very unique swimming action unlike any other crank bait on the market. They can be cast or trolled, even at high speeds, the bait stays stable and will not blow out. They run about 3'-6' depending on speed, line diameter, and technique. Also great worked as a twitch bait when casting.
