I just bought a Lowrance Hook 5x. An example, I am in 60' of water. Display shows large arch at 40'. Not moving. With a 20 degree angle the cone diameter at 40' is roughly 39'. Or in other words a radius length of 19.5' from my transducer in any direction. If my boat is anchored, pointing due north or 0 degrees, the right side at transducer is 90 degrees, stern is 180 degrees, and left side of boat at transducer is 270 degrees. My question is, what direction do I cast my lure or bait and how far do I cast it? Can you help me?
