is the ONE thing you can do to improve the ease and accuracy
of your locate? Improving the grounding of your transmitter
is usually at the top of the list. As we have learned in our
article on circuits, a complete circuit occurs when electric
current flows from the transmitter, down the target conductor,
and then back through the sorrounding dirt to the transmitter.
Electrical current cannot flow if it cannot return to its
source. Making this last connection effective, dramatically
helps to lower the resistance of the entire circuit, and allows
more current to flow.
The "ground" as it is called is that last step. It is the
connection from the dirt to the transmitter. Without a good
ground it is difficult to have a strong circuit, and therfore
difficult to create a strong field on the line or pipe. In
this article we will take a closer look at this very important
