A serious question - anyone know a rough figure to have a surveyor come to a house and in certain locations exactly map and mark true south?
The compass I use - a Silva - whilst OK, is far from accurate enough - user guesstimate more than anything. Tried a GPS, but again, not really precise as again, user error.
Was thinking if got a surveyor out with a laser theodolite etc...
Solar noon puts me within 2 minutes az on average. I would rather that was 2 secs
