I just added an 8612 to the front of the boat. I have a 1242 up there and wanted a dedicated livescope unit. I already had the 4″ tower up there so just went with that. A 6″ would be nice but I didn’t want the graphs sticking up to high. I also went with the inline (Type A) which provides enough clearance and viewing room for both graphs. It doesn’t stick out over the gunnel. I will probably switch them around to have the livescope in back and the 1242 up front. It’s just the way I fish and how close I am to the front. Don’t think I would change anything, but you might want to see if anyone has some photos they can share to give you a better grasp of how things are laid out. I can send ya a few just send me your number.
