 ```Hi Rich, For the last 40 years I have been using a 6 foot string at arm's lenth weighted by a crescent wrench to determine if my towers are vertical or not. I learned this trick from some power company pole installers in California in my younger days. You just stand off from the pole or tower about 50 or 100 feet and sight along the string to see if it is parallel to the tower or not. To determine 120 degree placement of anchors, I construct a jig from small wooden sticks about 3 feet long. Two of the sticks are placed at an angle of 120 degrees from each other and tacked in place with small nails and other sticks holding them there. You can check the accuracy of this jig by drawing lines on concrete parallel to the 120 degree sticks and rotating the jig to draw a third line. You can check the accuracy by placing the jig to measure the angle between the first and third lines. It should come out exactly right. If not, fix the jig and do it again. Once you have the jig made, you can sight down two legs of the jig at a time (with the intersection of the 120 degree lines of the jig placed right over the center of the tower) and know right where your anchors ought to be.
