I’ve got a flx-28, humminbird ice-55, helix 5 and lowrance hook 5. I’ve used them all for ice fishing and will grab my 28 every time. The helix and lowrance are only used for mapping. I’ve found navionics to be wrong 80% of the time. I suction cup the helix/ hook to my windshield or ram mount it on my wheeler.
I’ve also recently heard a rumor that marcum is wanting to split from rapala. If it’s true maybe they will come out with something new.
