2. To determine the lateral and therefore the actual
location of the RNLP, turn toward the left so that
the receiver is perpendicular (90°) to the drill string
and move the receiver forward. Again, move the
receiver slightly forward and backward until
pinpointing the location where the “+/–” signs flip
from one to the other.

3. At the RNLP, face away from the drill with the trigger held in and walk toward the transmitter. The
signal strength should increase. Watch for the “–” sign to change to a “+” sign. Once this occurs,
move the receiver slightly forward and backward and find the spot where the “+/–” signs flip from one
to the other. This location is the PLL along which the transmitter is located. Mark this spot as a line
across the drill string, representing the transmitter’s positive locate line.
