Using this scanning device will get you a lot more detail, no question. Whether there is any need for such detail is another matter. There may be a n...

Lately I've been using an AP20 tilt sensor together with candy cane style pole extenders to shoot inverts. Yields really accurate invert elevations. ...

@not-my-real-name What you are saying is that face of walls being on the right of way line is common statewide policy, and not simply your opinion....

Show me the case law. There has to be some.

I got one for under $7k total, including the mated rod and batteries. A second one ran under $10k. You have to wait for the deals. As a government age...
