    How do I site, or walk , as straight line to mark a conduit Run w/o a Survey Transit

    We're dropping 400' feet of 1 inch conduit into the ground. I have to mark a straight line line with a Marking Wand for the Utility Locate and the Backhoe.
    Best thing is to have someone set a survey transit up and watch me -if I wander out of the walking Path-I get a yell to correct my direction.
    Does anyone have any suggestions/ Follow a pickup with a steering wheel held dead center?

    Not the birightest question someone has ever posted on this forum, but I might get some helpful feedback.

    Stand at point A, pick a landmark inline with point B and start walking. You can also use a compass.

    How flat is the ground? Maybe just lay out a rope.

    Or get a plumb bob with lots of string.

    I’ve used a bucket of pull string. Drive a stake at each end of where you want to go, tie string to one end, tighten and tie off at other end, then run your marker along the string.
    Cheap easy way to make a nice straight line. Finding someone who can run a trencher straight along that line........well maybe another story.

    Take a laser level or pointer and set it at point A pointed at point B. Starting at point B, walk toward point A while verifying the laser dot is hitting you. Mark the ground with spray paint as you go. This procedure is best done when it's dark out.

    A string will bow. A laser will not.

    It helps if you mow the grasses along the path of the string-- fewer snags to make the line crooked!
