I'm thinking of upgrading my electronics in the spring. I currently have a Humminbird 788ci/HD down image and a 798ci/HD duel side/down image. both are 2 seasons old. Both have internal GPS and chart plotting. Great units but it is time to upgrade. I would like to change to Lowrance , I was thinking about the HD7 Elite (Gen2, non-touch) for both the drive/trolling motor. Does anybody have any suggestions on what I should get. I fish local Tournaments and Big Water most of the time. Erie is my primary location to fish. I would like to get a Gen2, non-touch units, possibly a 10 is my budget will allow since I have to get 2 units?? thanks
