Ok, I know this has been asked many times, but either the search on here don't work, or I'm an idiot:lol: Can't find any previous threads for some reason. I'm looking to get a gps, maybe in a week or 2, and looking for the most detailed as far as countours for sag. bay and great lakes. I thought I like the hummingbirds, but looked at them and the lowance today at Franks, and the Lowrance looked better. but neither looked as detailed as what I thought they would, unless the map they show you in store is different than on the water. Thanks for any help. The 2 I looked at were the hummingbird 788 hdci, and Lowrance HD5 insight. Both were combos and both same size screen, and both were $699.
