I’ve used Map Create. The user interface in my opinion isn’t real user friendly…but it does work great for putting names on marked waypoints and changing a group of waypoints into routes. Being I fish the river, I’ve used the routes (too) many times in the fog ect. BIG time save on the ‘sippi last year when a heavy fog rolled in and I had better than 5 miles to get home…with out a route or at least marked waypoints…I would have had to spend the night. What I mean by marked waypoints is some are fishing spots and some are navagational waypoints…when going 7 to 10 mph in a fog, you don’t want to confuse the two!
I use the map that comes with the 19. I’m sure the premium maps are better but I think I should note that in going to the ‘sippi from the croix my map says that I’m boating right down main st. in Prescott. So you can’t believe the shoreline with the built in map.
Back to Map Create, I’ve marked long irregular breaks on the water, then on my computer named them which gives me a good path to follow trolling or jigging.
That’s really all I’ve used it for.
