BW made a good recommendation for the FL-8. I would also look into the Humminbird Ice-35. Yes, it’s less popular with most avid anglers, but they are an incredible value for the features you get. I bought an Ice-35 the year they came out, sometime around 2006? I sold it to a friend of mine 2 years ago to upgrade to an FLX and Helix 5. He loves the unit and it has worked flawless since day 1. The target separation leaves a little to be desired, but the occasional angler would barely notice it over a more expensive unit.
The Marcum units are also being marked down on their website to clear them out for the new models they released, some good deals can be had!
Pick 2 or 3 units you want to check out, head to the ice show and buy the one you like the best. You will not find better deals on a new unit.
