You basically won't need too much. You've already got all the wam clothes you need from all your hunting stuff. I have everything else you would need, but here are the basics.
ice fishing rod (one with a real is ideal but not needed) but you should look for one with some sensitivity like an ultra light rod
2-4lb test line
ice fishing jigs and something to put them in (most jig holders look like a metal cigarret case)
depth finder (a small lead weight with a metal clip molded into it)
ice scoop (for cleaning out the hole)
bucket with lid (cut a small half cirlce out of the lid, just enough to fit your rod and an ice scoop through)
ice spub or auger (I have both of these) I like to use the spub to check for unsafe ice during the early and late season
If you want to go out with me for the first few times you won't need to bring anything but yourself.
