Just walked the majority of my 20 acre parcel. Each stake/corner is within 10ft of the advertised boundary on HuntStand. I have found them to be pretty dead on at public land here in central VA as well. Public here (WMAs and State Forests) are very well marked in the field. To “mistakenly” cross those boundaries using an app and your eyeballs, would almost have to be negligent. I hunt many areas that transition from State Forest to WMA (regs change within the 2 so it matters) and I am well aware when I cross those borders, without using my app. Again, I am only speaking for about 5-6 counties in central VA. Funny thing is, I can be 10ft on the wrong wrong side of the border and it not be open to either sex, or have an antler restriction. So I’m constantly planning my walk by boundaries when going into these type of areas.
