Jim,
If you own or can borrow an underwater camera, bring one with. It will make your day much more enjoyable and exciting to watch what is going on and you will learn a lot about fish habits. This is where underwater cameras are most beneficial because you can fix them in position on the ice and constantly monitor your bait. I've had one grandchild monitor the camera and another on the pole fishing for perch. The perch would deftly suck the bait into its mouth without a clue there was a bite. But the instant the fish did that, the cameraman would yell "pull" and they got'em every time.
