I ran a small humminbird (797) on my Crestliner, but sold that boat two falls ago. That small unit taught me a ton about large lake structure….seeing the defined edges of (and holes within) weedbeds, seeing isolated rockpiles (the best kinds….the ones not on maps), seeing scattered, suspended fish, finding cribs, etc. All of that was on lakes and reserviors in MN and WI.
Last year, I ran a 997c on a Skeeter WX 1880 that we used on the Mississippi to film a couple of IDO-TV episodes. You haven’t really seen a wingdam, or a washboard bottom on a river until you’ve seen them on side imaging. No problem identifying fish either!
I’m so conviced of the power of side imaging that the Skeeter WX 1880 that I’ll be running in the FLW this year will be equipped with two units: an 1197 at the console, and a 997 that I can move from kicker to bow. I already know that a big portion of my prefishing will be done by staring at a graph.
