I'm sure I'm going to repeat as lot of things, but I have a pretty short list of things that got me from clueless to generally successful when started icefishing about 15 years ago.
As an aside, I totally love the dock demon-type rods, and buy the $10.00 with the spin-casting reels for kids, all the time.
One, get on YOUTUBE and watch a bunch of underwater videos. That's how I learned how fish act, and what lures look like underwater. (hint; most jigging just looks silly, the lure just going boing, boing, boing, like nothin in nature does.) Being limited to vertical presentation is unique. It will help you make sense of what jigging different lures should look like, how fish bite, how truly light winter bites can be (it was a revelation to me), and how fish relate to your offering at different depths (sometimes you have to be TOUCHING the bottom, sometimes a foot off, sometimes they chase things down or up....), what spooks em, etc.
Second, you absolutely MUST be able detect strikes. I can't catch anything but trout without a tiny slip bobber, spring bobber, or noodle-tip rod. For panfish, a slip bobber needs to be the size of a marble. 6 lb test is WAY too heavy. Low-memory, low stretch, sensitive line helps. I say this without criticism, but places like PV should be a slam-dunk for small-mediocre perch almost anywhere you fish. That makes me think it's more likely you aren't seeing bites than that you aren't getting them. My first GOOD "spring bobber" was a small colored zip-tie taped to the end of my pole. Sometimes a bite = your line perfectly straight instead of slightly bowed. Often the tug you see/feel is them spitting it out.
Sometimes fish are really on the feed and bite everything I put down a hole, so I use larger lures with lots of action. More likely, for panfish anyway, I NEED quality 2- 4lb test and tiny lures. I was fishing with a buddy at Mantua once. He was using a 1/64 regular jig with a little tiny Maniac plastic. To him, that was a very small jig, but he got nothing until I gave him a size 16 hook Ratfinkee. Try all kinds of things, and DOWN size when needed.
MOVE! You absolutely need to find the right hole. If nothing bites in a few minutes, move. I'll drill a dozen holes and catch 3/4 of my fish through one good spot. I try to vary depths and topography while searching.
Sonar matters for knowing you aren't over a dry hole and finding suspended fish. I finally got a hand-held one that wasn't a complete cheapo, and I am learning, but my last outing 3 weeks ago, I would have caught 1/5th the fish I did, if I hadn't been able to drop my bait right above their noses.
Always take a variety of baits; I always have waxies, garden worms, mealworms, and perch bits/eyes with me. Also, before you get a lot of lures, get a variety of lures and ice jigs. I have hundreds of jigs in my box, but consistently use just a few, probably becasue I use them a lot, and I know HOW to use them. Some pretty expensive stuff (Hali jigs, swedish pimples, is definitely worth having ONE of. Also, small wiggly plastics are a good investment that I have to bite my
and swallow my pride to pay what they want for em.
Gear is a LOT cheaper on Ebay/Amazon.
Last, having a mentor helps. I learned it all on my own..............oh, wait,.... except for a lot of people here on this site who taught me a little at a time, sometimes just one detail here or there about timing, etc. I had been fishing for perch a full crank from the bottom, thinking that WAS "on the bottom", when USUALLY literally almost touching the bottom is what you want.
