I love mine, for ice I use the flasher more than the graph, mine came with a suction cup transducer which works great with my kayak. The skimmer gives a wider 20 degree angle the ice transducer gives you 6 degrees so the skimmer is worth the extra bucks.
I LOVE MINE!!! so do all the first timers i bring out with me, the graph screen takes less than a minute to understand. I have found one "problem". I have picked up interference when in the middle of a dozen flashers. Also, first thing is to get rid of the little transducer arm and metal rod. Get a $5 transducer float with zip ties.
i have had interference issues with mine as well .... there is a noise reduction setting that helps but in deep water you will need to find yourself a little elbow room .... which is fine with me
