one of my concerns is this unit might be to much for my needs, my usage well be small inland lakes in Michigan at 60 ft. or less in depth fishing for crappie. I never had a gps and my thought is if i had a hand held gps i could use it when I'm in my boat or in the winter ice fishing. Any one else thought the same and realized having both is a pain in the ass

what would be a good choice for a fish finder if i decided to go with a hand held gps, also i downloaded the demo of this unit and the sonar part seems pretty easy , the gps i haven't totally figured out yet
