Greater target separation, better interference rejection and the broader frequency spectrum as stated above.
I have the Helix 7 and love it. The ice versions have a much improved flasher view over the non ice and the
ability to view the flasher and traditional graph at the same time although that might be a bit trickier
on the Helix 5 with the smaller screen unless you have good eyes

If strictly for ice fishing, don't spend the money for DI or SI versions as they don't work
to full benefit sitting still.
