Howdy hoshour,
This is Eric Siegfried, the founder of onXmaps and Hunting GPS Maps. There is a reason the WY Game and Fish recommended the HUNT app or HUNT GPS map for Garmin. We have worked closely with game and fish agencies for years to make the land ownership information the most accurate it has ever been. Other apps and gps maps out there use general ownership data from federal agencies that is inaccurate and very out-dated. Trust the app that game and fish law enforcement officials across the US trust. Talk to any game warden and they'll tell you the HUNT product lines give them the most confidence in the ownership information and property boundaries.
Hunt smart,
Eric
