Personally I like the snapshot/waypoint feature. If I think something is important enough to take a picture of, it's important enough to mark a waypoint. It's a one step procedure rather than a 2 step procedure. Now if you want to remove the waypoint, it does take a second step. I imagine Lowrance requires 2 steps to mark a waypoint and then take a snapshot. I would probably be admiring the picture so much, I'd forget to mark the waypoint. I actually use 2 machines, a Bird for sonar, and a Garmin for GPS, mapping and waypoints. That way i don't have to share screens. I'll use the Bird to stop the screen, and mark the waypoint. Then I'll mark the waypoint again with my Garmin, but correct the Garmin to the original Bird mark. As I would have traveled by the actual brushpile by the time I marked with the Garmin. Works well for me and if my waypoints in the Bird get cluttered, I just delete the works as I already have them on the Garmin.
