I shot the angles for the RMYoung sonics. I used a combination of a compass and the theodolite.
The compass was set with 0 degree deviation. When we get the new datascope I will take another set of readings.
The sonics were mounted with the N direction pointing toward the East.

10/25/2016 - We found the compass on the Theolite was no good, based on comparisons with the binoculars. We used the Theolite to align the sonic and then used the binoculars to measure the angels.
