This is one of the most commonly asked questions in the crank fishing game, and for good reason. If you are looking to get deeper into the water with your crank baits, there are a couple of different methods that you could try. The first and most obvious would be to choose a deep-diver crankbait that is designed to hit those depths. More often than not, these will be advertised along with their depth potentials. Generally speaking you are going to be looking for lead-core line and potentially the addition of a couple of snap weights.
