I've only been ice fishing for 3years am totally hooked on it. I fish mostly ponds from 5' to 20' deep but would like to come up to the big pond someday( lake erie). I do fish Erie a few time during the warm time of year. Anyhow looking to buy my first ice fishing sonar. Looked at alot of them online but not sure what to get. Kind of liking the MarCum showdown or the LX 6 both are digital displays. Any thoughts on what would be good for a beginner using electronics.
