20+ years ago, I had a handheld thru-ice transducer. It was blue shaped like a flashlight with a lanyard. I just moved back to Michigan from Florida after 18 years and just got back into ice fishing.
I just did a search, they are still available, Marcum has one, it’s the MarCum LX-I Digital Handheld Sonar, it has a digital read out and 2500W. It was a definite time saver!!
