They have tipups with a rod included so you fight the fish on a rod instead of handlining it. Depends what you want. I'd rather catch them on a rod and avoid handlining the fish for the sport of it.
If you get the regular tipups, of which there are many types, be sure the reel is in the water and not the type that is exposed to the air, which freeze up.
