I have a garmin 64s and the onx hunt chip for Montana. It has all land ownership and boundrys, hunting districts, etc on it. Chip was $100 and requires a subscription, $30 year. Onx hunt also has a smartphone app that you have full access to if you have the subscription. If im in an area with cell service I like the screen on my phone better, but if you loose service, then i use the chipped gps.
You can get the onx hunt app subscription without a gps, $30/year, it keeps all ownership information up to date. You can download maps to your phone for use if youre out of cell service areas. They are detailed and use a lot of memory.
Onx hunt maps are at www.onxmaps.com, they have all 50 states and various packages for one or more states.
