path. This information will be used to determine if the
transmitter has maintained its heading or moved toward
or away from the intended bore path.
Rather than track depth readings, you may choose to
track signal strength, in this case make note of the signal
strength at the location you mark.
7. Walk further to the side of the obstruction with the locate
line in the box.
8. Again move the receiver in a fore/aft direction to find
where the ball flips. Mark this location on the ground and
take a depth reading making note of the value (and/or
signal strength) and the distance from the bore path.
9. Once more walk further to the side of the obstruction with
the locate line in the box. Move the receiver in a fore/aft
direction to find where the ball flips. Mark this location on
the ground and take a depth reading making note of the
value (and/or signal strength) and the distance from the
bore path.
10. Connect the three points to make a line. This line should
perpendicular
(at a 90° angle) to the transmitter’s
heading. If there is a problem, contact DCI.
11. Drill forward, tracking the locate line while walking parallel
to the bore path and maintaining the noted distance from
the bore path.
12. Keep the trigger held in as you walk forward to verify the
slant distance to the transmitter is maintained. If you are
tracking using signal strength, leave the trigger out and
observe that the signal strength is maintained.
13. Periodically stop drilling and find the three points at the
noted distances parallel to the bore path to verify heading
is maintained.
14. If the depth reading increases or the signal strength
decreases, the tool is moving away from you and needs
to be steered back on track. If the depth reading
decreases or the signal strength increases, the tool has
moved toward you and needs to be steered back on
track.
15. Use the transmitter’s pitch to steer the transmitter up or
down if required.
