My friend bought this unit with the ice transducer and battery and a second transducer for the boat. It works very weel for ice fishing in flasher mode. It has more power than my Ice45 but it does have some drawbacks. It chews through a battery very fast so it pays to have a spare, also when fishing in flasher mode turn the background to black instead of white and turn the brightness down to conserve battery. Second issue is the screen size is smaller when using flasher mode and there is a slight delay in the screen refresh compared to the ice45, will this make a huge difference, no, I use both and you will catch just as many fish. For the price it is very versatile and can switch between your boat and ice fishing very quickly and costs half what the other model does.
