Locating
2. Walk forward until the "+" sign changes to a "–" sign. Note that the target has moved into the box.
Target in the Box
3. Turn the receiver 90° from the transmitter heading while holding the receiver steady and level, and
find the point where the "–" sign changes to a "+" by moving the receiver forward or backward as
needed; the target should be in the box. This is the RLP. Release the trigger.
4. Mark this location as the RLP.
5. Connect the RLP to the FLP by a line. This line represents the transmitter heading.
Off-Track Locating
The off-track locating technique is useful when it is not possible to walk above the transmitter due to a
surface obstruction or interference. Using the locate line’s perpendicular relationship to the transmitter, it
is possible to track the transmitter heading and also to determine if it is maintaining its intended depth.
This method is only valid if the pitch of the transmitter is close to 0% and the ground surface is level. The
transmitter pitch must also stay constant for the most accurate off-track locating. A full description of the
off-track locating procedure follows.
NOTE: The off-track locating method is only effective when the pitch of the transmitter is the same as
the pitch of the terrain and this pitch value is less than 10%.
