...for me today. Starting two zones where 480v electrical lines to lights go through the area in several places. Electrician has been out and marked the locations but depth is my main concern. His locating equipment kept getting feedback and the lines are anywhere from 2" to 12". We've probed and can't find the conduit because the ground is so hard and there are mega roots from a line of birch trees in the area. Guess I'll go REAL slow and hope for the best.
