Preparing for Off-Track Locating

While still holding the trigger in and keeping the receiver in the same orientation, step to the side of

the tool another predetermined distance (P2) further away from it. Move the receiver forward and aft

until you can see the ball jump from the bottom of the screen to the top of the screen (or vice versa),

then mark this location.

5. After finding the three locations P1, P2, and P3 to the side of the transmitter, connect these locations

with a line. This is the locate line. Because the LL runs perpendicular (at a 90° angle) to the

transmitter when the transmitter is level, it is possible to determine the heading of the tool. By

comparing the slant distance or signal strength at the predetermined distances of P1, P2, and P3, as

the tool progresses you can verify if the drill head is moving away from or maintaining the intended

bore path. It is also important to track the pitch of the transmitter to verify that the tool is

maintaining the desired path.
