I know compassess are not the greatest especially around lots of steel. I was thinking we could hold it a few feet from the tower on top to get a bearing on a landmark.
The way I currently do it is draw a line on google earth and find a landmark in one of the directions I need. It's fairly easy after aiming one sector based on a landmark to sight 90 degrees off of it to find another landmark for other sectors. A square is occasionally helpful. Issue is occasionally that landmark you thought would be easily visible is not that identifiable from tower top. I just wanted something cheap, easy and could always be in the toolbox.
