Best Helix size for bow of 175 Tracker with 8 spider poles?
I have an older Hummingbird 597 ci HD at the helm. It works just fine, but Im wanting a Helix 7 or 9 with SI and move the 597 to the bow. But, the more I have thought about it, I spend the majority of the time on the bow and thought maybe I just need to put the new unit up front until I can replace the rear as well. I know the better unit should be at the helm for searching structure and unfamiliar lakes, but maybe not in my case with local lakes. Im thinking I may not have enough room for a 9" up front and considering a 7 since I can elevate it with a RAM mount and get it closer. My eyes aren't the best, so I want to get a big as I can, but also what I can afford.
Thanks for any input
