I'm going to have to be the tough one to please. I don't have a single, hands down favorite in anything on my boat. There are things I like about each brand of sonar graphs that I think they excel at, that the others aren't as sharp on. Like right now...for side imaging and down imaging, I think Lowrance has surpassed them all with the HDS Live and Pro units Especially for ease of use and showing stuff in the water column. But...their maps suck for TVA lakes. Specifically, not being able to do water level offsets for winter drawdown. Garmin is probably the most well rounded for offering a little bit of it all, really good. Great sonar returns, maps, and they have the market topped for forward facing sonar. Humminbird used to be my favorite but I have kinda phased those units out from my boat. The last one I have on there is a 10" Solix, which is soon to be replaced with a Lowrance HDS Live 12". Trolling motors...I have the Ultrex and it gets the job done but I still would like to try the Force and the other new offerings.
