predetermined distances of P1, P2, and P3, as the drill head progresses, you can verify it
is moving away from or maintaining the intended bore path. It is important to monitor the
pitch of the transmitter to ensure the drill head is maintaining the desired depth.
4. As drilling continues, steer the drill head to maintain a constant signal strength at each of
the points P1, P2, and P3. If the signal strength decreases, the drill head is moving away;
if it increases, the drill head is moving toward the side position.
Differences in pitch and topology elevations will also affect the signal strength and LL
position as the drill head progresses. Using three (or more) off-track points gives you
more information to help recognize the potential adverse effects of interference at any
one point.
Off-Track Locating
Target Steering
The Target Steering

locating method allows the receiver to be placed ahead of the drill head
and used as a steering target.
In general, Target Steering should be used to maintain a bore path, not
to bring a significantly off-course bore back on track. If needed, use front
and rear locate methods to get back on course.

In situations with significant pitch changes, such as during the entry/exit or areas with
changing topography and elevations, the up/down steering information on the remote display
may not be accurate. In these situations, only the left/right steering information should be
considered accurate.
