Finding the Locate Line (LL)
6. Continue walking toward the drill rig or the last known transmitter location. Keep the
locating ball on the vertical crosshair and observe that the signal strength is increasing as
you get closer to the transmitter.
Receiver Locate Screen, Moving Toward LL, FLP Behind
If the signal strength decreases, you may actually have just located the RLP. Position
yourself farther away from the drill and start over at step 2.
7. When the locating ball reaches the bottom of the screen, the locate line appears and the
ball turns solid black to indicate your focus should now be on the LL.
If the locate line does not appear and the ball flips to the top of the screen, hold the
trigger while moving the receiver in a forward/backward direction over where the ball flips.
This action should re-reference the receiver to the transmitter’s signal and bring up the
locate line. If it does not, return to the FLP to re-reference (see step 1).

Actual Position of Receiver
and Transmitter
Do not rely on the alignment of the ball with the vertical crosshair to identify the left/right
position of the transmitter. Accurately locating the front and rear locate points is required
to determine the transmitter’s lateral position (heading) and take accurate depth readings.
