Replacement Part List

flip the toggle switch to “Near”. As you move close to the transmitter,
continue to maintain a meter reading in the middle of the scale. When you
reach what seems to be the maximum signal, and every direction you move
from there has a lower signal, you have reached the Peak Spot.
Mark this spot, then move off in another direction and repeat the locating
procedure. Keep doing this until you always return to the same spot. You
should be able to narrow this rough-in area to within a few inches.
If you’re just locating a septic tank, and knowing its depth is not critical,
you are ready to dig. The Peak Spot you have marked is directly above the
transmitter, near the inlet baffle. Also be aware that if the transmitter is turning
in the tank, it is virtually impossible to determine its depth.
If you need to know the lay of the line or the dept of the line, read on.
Determine the Lay of the line
Before you can determine the depth of your transmitter, you mast establish
the lay of line. Do not skip this step!
Step 4or 5 feet away from the Peak Spot you marked. Hold the receiver
level straight in front of you at waist height, as before, but don’t wave it back
and forth, just hold it straight. Adjust the sensitivity so that the meter reads
about the middle of the scale. Walk in a circle around the Peak Spot, keeping
your inside shoulder pointing at the Peak Spot. This would be called a “pylon
turn” if you were flying an airplane.
As you walk the circle slowly, watch the meter and listen to the sound. At
two distinct points in the circle, the signal strength will suddenly drop, then
come back up as you move further. These are “null” points. Take the time to
precisely determine these points. And mark them (the point is directly below
the center of the rod). you will find that they are directly across the circle
