I'm an adult convert to ice-fishing. My buddy has a marcum flasher and I spent a few years gearing up enough to fish by myself more. I ended up going with a Helix to use on the ice and for kayak fishing in the summer. It's been a fantastic unit. I think if I had to do it over again, I might spring for the 7, but the 5 has been awesome, so no real complaints. I mostly use the graph only mode as well.
