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.
As long as the FLP remains on target, there is no need to
find the RLP on every rod. If steering is required, a quick
look at both the RLP and the FLP will ensure the
transmitter is still on target.
While tracking on the fly using 10’ drill pipes the operator
should walk forward from the last FLP approximately 10’
and place the receiver down in line with the path created
by the RLP and the FLP. While the drill operator is drilling
toward the receiver, wait for the arrow to flip. You are
within inches of the new FLP, fine tune the left-right bar
and mark the new FLP. Now simply walk back to the LL
being careful to stay in line with your last FLP and mark
the new location of the transmitter and record the depth.
