RTK for boundary work

Since a forester will have the deed, take a look at the following post. I think your use-case fits this well.

Once a RTK site calibration is performed, you will know exactly where you are in relation to the parcel in real time, to within an inch (depending on canopy obviously).

IE: Any SparkFun RTK device (with Bluetooth), a smartphone, PointPerfect, and SW Maps.

These days, there’s not many applications where a Base/Rover is worth it (if you have internet access).
