OK, I am outfitting my new Ranger RT188P and with all these different Garmin units, my old brain is about toast. I have decided on a 106UHD with a GT56 transducer for my console unit. I plan to purchase Livescope for the bow. I orignally thought I would get the 126UHD but now I see there is a 122UHD that is cheaper and the only difference I can find is the maps. Would I be wasting precious $$ if I got the 126 if it was a dedicated Livescope unit? Are there other alternatives? Dang Humminbird and networking were easy compared to this!!!!
