This is exactly right! You are trying to put a buffet right in the fishes face. It's a must to see depth, especially for suspended fish. You must key in on the prime depth. Same with fish on structure or drop offs. This can be done with a transom mount transducer or through hull, but it is ideal with the trolling mount and console unit turned around to see depth changes. Allowing you to better zero in on depth changes or structure.
