This little handheld fish finder does just that. Yes, it reads in metric, but that's it not that harmful. I've only tried this in shallow water (3-5ft) and since I could see fish in the water the sonar picked up those fish. It's interesting to see how the sonar reads in deeper water with fish at different depths. Very excited to use this!
