I have a 1158 DI on the bow where I spend 99% of the time. If I had a Helix 12 DI with mega I would have it up front where I was fishing and move the 7 back to the console. Vertical jigging with the 12 up front would show a lot of detail under the front of the boat. Congrats on the new unit and hope you enjoy it. Let us know how you like it.
