Hey guys, I'm wanting to upgrade my units. I currently have lowrance elite 7 on front and elite 5 on console. I'm looking at helix 10 mega chirp or hds 10.. I only fish ky and Barkley lakes, and want the best mapping for those two lakes. And the most user friendly.. also eventually I want to get a trolling motor that I can link up to the GPS on the units. So what do all of y'all have on your boats?
