You might want to rethink the mixture of Lowrance and Hummingbird electronics. I would stick to one or the other. If they are the same brand, you can find brushpiles and save waypoints on the console, then move to the bow and, if the units are networked together, you will see it on the bow graph's chart. You can't do that with one of each. I run an HDS8 on the console (flush mounted) and an HDS7 flush mounted on the bow. Surely, you can trade the 7 that comes with the boat in on a hummingbird? If not, maybe you can have them ship it unmounted, sell it, and buy a bird to go with the 1197?
Again, not knocking Hummingbird, just think it through and go with one brand or the other. If you don't you will be kicking yourself in the very near future!!
