Tracking “On-the-Fly”
If you are running at 0% (0°) pitch over level ground, the predicted depth will be the actual depth. In this
case, all locating can be done at the FLP while the tool is moving.
Once the transmitter has been found and its heading is on line, position yourself the distance of one rod
length in front of the FLP on the intended bore path with the receiver facing the drill and sitting level on
the ground.

Depth readings and data points for the Log While Drilling (LWD) function may be taken at the FLP or at
the LL. It is necessary to hold the trigger in to view the depth or predicted depth, to send the depth
reading to the remote display, and to log data points for the LWD function.
WARNING: Do not hold the trigger in unless you are precisely at the FLP (target centered in box). If you
are ahead of the FLP, you will set an incorrect reference that causes a ghost locate line. In
this case, you must reference again at the FLP.
