Marking Locate Points
The locate points (FLP and RLP) and the locate line (LL) must be found and accurately
marked during the locating procedure. To mark a locate point, stand with the receiver level at
the locate point. Look down the vertical axis that runs through the center of the display to
project a plumb line to the ground. Mark where this plumb line hits the ground.
Plumb Line for Marking Locate Points
Locating the Transmitter
Falcon F5 can locate the transmitter and its heading while it moves, whether in front of the
transmitter, behind it, or beside it. It can locate the transmitter while facing toward or away
from the drill rig.
The standard method described in this section guides the receiver to the transmitter while
standing in front of it, facing the drill rig. This is the recommended method for locating. As you
continue to drill or as the bore path curves, you may be facing the last marked locate point
rather than the drill rig.
