druthrbfishn, I'm guessing you already are very well familiar with the 522C in graph mode, which you must know is FAR superior to the flasher mode. If the transducer on your boat is a skimmer mounted on the stern, it's very easy to adapt it for the ice. A stiff wire or emt 1/2", about 7" , a bolt and a small float of foam and there's your ice ducer. A small box and battery, 7ah to 9ah, a small charger and you're done.
Otherwise, if you're not handy but wealthy, well, you know.
