I used to have a fishing buddy and it got the job done, but the 6 C battery thing was a total pain sometimes. If you have a few more bucks to burn, I HIGHLY recommend the Humminbird 345c Portable. It's a self-contained unit in a carrying case that has a rechargeable battery and a transducer with a suction cup. It has a bunch of different modes and even a flasher mode for ice fishing. They sell a separate ice transducer, but you can definitely tweak the one it comes with to work through the ice. I think Lowrance has a portable unit too and so does Garmin. The all have a case that sits right on your deck, bucket floor whatever, have rechargeable batteries and suction cup transducers. I think they're a better alternative. That's my 2 cents.
