Locating
8. While standing on the FLP and facing back toward the drill, it is possible to “sight in” or align the FLP
with the RLP. This axis line is at a 90° angle (perpendicular) to the LL. Where this axis line crosses
the LL is where the transmitter will be found, below ground.
9. Position the receiver at the intersection of the LL and the line between the RLP and FLP—you will be
above the transmitter. From this location you can observe the depth of the transmitter by simply
holding in the trigger. You will also see the ultrasonic setting and, in the bottom left corner, the
receiver’s battery status.

If you choose to locate the transmitter by standing out in front of it and facing the drill, you can use the
same technique as described above. However, you will first find the FLP, then the LL, and finally the RLP.
Remember that you must “lock in” on the reference signal at the FLP (instead of the RLP) if you use the
method of locating from the front, facing the drill.
It is not always necessary to find both of the locate points (RLP and FLP). However, for the most accurate
locating, DCI recommends that you find both the FLP and the RLP. The line connecting the FLP to the
RLP will provide you with the heading of the transmitter (tool) as well as its position below ground. The
heading information can be particularly useful when the transmitter (tool) hits something that deflects it to
the left or right, resulting in a change of heading.
DCI does not recommend locating the transmitter using the peak signal method.
NOTE: It is very important to position the receiver accurately. The depth reading can be in-
accurate if the receiver is not positioned directly over the drill head.
