OPERATION
"Walking a Line" (X100 transmitter shown)
Pinpointing is similar to passage detection except there will likely be no
need for recording, as pinpointing is a "hands on" operation.
From last known position, proceed downline, keeping
TRAXALL as closely aligned with pipeline as practical.
Observe History Window closely. As you approach
the transmitter, the graph "climbs." When you see the peak,
you have just passed the transmitter.
