MyFishFinder.com Just like iceshanty but warmer
I use this one: https://a.co/d/42yAsslThere are a ton on Amazon from these no name companies, probably a lot are the exact same thing. Surprisingly, it’s pretty decent quality. It’s been dropped on the ice more than once. They go on sale, I know I paid a lot less than the $18 it’s listed at now, but that was 3 years ago or so
