As the drill head advances, the FLP should travel along the receiver’s vertical crosshairs, indicating the drill
head is still on line. Once the FLP is in the box, hold the trigger and confirm that the predicted depth reading is
as expected.

You can find a training video on Off-Track Locating at www.youtube.com/dcikent.
Use off-track locating 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’s heading and also determine if it is maintaining its intended depth. The off-track locating method
is only effective when the pitch of the transmitter is 0% (0°) and traveling under flat ground.
To explain how the off-track locating method works, consider the example of an obstruction that is on the
intended bore path, as shown in the figure below. The transmitter is about to go under the obstruction.
1. Stop drilling and find the locate line (LL) of the transmitter by putting the line in the box.
2. While holding the receiver in the same orientation, step to the side until you reach a predetermined
distance (P1). Move the receiver forward and backward until the ball jumps between the top and
bottom of the screen, then mark this location and note the signal strength. While still holding the
receiver in the same orientation, do this two more times for off-track points P2 and P3.
