I own navi-track-1 and the navi-track line transmitter 10 watt 3 years old? I need to locate a pvc electrical conduit (buried) the line runs through a ball field on one side the pull box is above grade metal conduit and then goes under ground switches to pvc. The line runs about 250' or so and comes up on the other side. So what is the most accurate method to locate? should I trace with the line live using inductive clamp? or shut off power open boxes and clip alligator clip to one of the wires and then run a jumper wire from the other end to the other alligator clip that is grounded or clipped to jumper wire to make a circuit? what is the best freq. to use? any tricks or tips?? with sewer camera I'm dead on but dont trace much! how accurate is any of the methods with depth and distance
