997 has a bigger screen and more pixals. Which means a way better pic. I have the 797,wish I had the 997 but could not see droping another 1000 bucks. Am I happy with the 797???? Well not a 1000 bucks happy
would I do it again,,,not really
Smaller screen,hard to see in bright sun,not a very crisp picture. All add up to a 1000 buck semi mistake. But I will live with it and keep using it. Best thing is the maps on it and GPS. I fish Weiss alot and that lake can be a dangerous lake due to shallows and stumps. When I'm running the lake it will keep me in the river channel so I won't run aground
