Tracking on the fly may be used once the bore path is established and level. This
tracking method will increase locating speed and in turn the speed at which the
bore can be completed. Activate the Bore
- To screen by pressing the enter
button at anytime. To return to normal walkover mode, simply press the enter
button again. For more accurate left right sensitivity, always stay out front of the
FLP when using Bore
- To.
Note: Both the operator of the drill and the locator see the same screen in both
modes, this way minimal communication is needed between the two operators.
Simply keep the Target Ball centered and
you
’ re headed directly to the receiver.
Depth is displayed in real time correcting
for pitch changes giving both operators
the ability to see the
Predicted Depth of
the head if drilled all the way to the re-
ceiver. In Figure 1 view, you
’ ll notice
the head is 9’1” behind the locator and
headed slightly left of center. Because the pitch is minus 5%, the calculated depth
will be
8’8” deep when the transmitter arrives.
The process for tracking on the fly is quite simple, after the first rod or two and after
establishing line and desired pitch, move forward of the FLP the same distance as
one rod length. In other words, if you are using
10’ drill pipe, move 10’ ahead of the
last FLP. Place the locator on the desired bore path and point the locator where
you want to go. If the transmitter is pointing directly at your locator, you will see
the
Distance to the Head and the Target Ball directly on the Vertical Line indicating
