I bought MEGA live last spring, so have a few ice hours on it but not a ton. Only managed a couple days of open water fishing so never bothered to use it in the boat.
The more I use it the more I like it. It certainly makes fishing more interesting, as you have much more information in your face compared to a traditional sonar. My next trip out is going to be focused entirely on learning the forward facing mode to find weed lines, structure, etc.
Is it worth it? Probably not. It’s a glorified (and expensive) toy but whats the point of working if you can’t have a little fun with the income.
