I read some reviews and watched some videos on youtube on the unit. Reviews are a bit mixed, people complaining about not being able to see fish. I guess fish dont show up like they would on a regular fish finder as a fish or an arc, on this one they show up as a ball. Most of the videos i found on youtube were European so good luck understanding some of it lol.
I am counting on the unit performing well ice fishing, I`ll be able to tell you more after few outings
