I started using the Elite Hunt Membership from onX Hunt during last winter's ice-fishing season. Using the nautical overlay, I was able to target areas I wasn't familiar with. The structure and depth on the overlay was damn close. We even marked danger zones and were able to share with friends who were fishing the same area. An officer with New York State Environmental Conservation sent me to the areas to put the message out about some thin ice and open water. I'll be using it this fall for a North Dakota trip so I'm pretty excited. I'm still new at using this app and new for this year North Dakota is allowing online land posting I believe. It would be nice if there was a overlay for that in the future.
