Plus/Minus ("+/–") Locating Method
The plus/minus method is the same as that used in DCI’s Mark series receivers for finding the front and
rear locate points. This method is similar to the standard locating method except here you hold the trigger
in and use the signal strength and plus/minus signs for locating. In general, the plus sign ("+") means
move the receiver forward, and the minus sign ("–") means move it backward, to find the locate point.

Plus “+” = Move Forward
Rear of

Minus “–” = Move Backward
Using Plus/Minus (“+/–”) Indicators for Finding Locate Points
The front and rear locate points each represent a point where the sign changes from positive to negative.
It doesn’t matter if the receiver and transmitter are facing in the same direction or in opposite directions,
the "+" sign will change to a "–" sign at either of the locate points.
Anywhere along the locate line, when the receiver crosses it, the "–" sign will change to a "+" sign. The
position of the transmitter along the LL can be determined by finding the FLP or RLP.
Finding the FLP
1. Stand out in front of the drill head (facing the drill) at a distance of approximately one drill rod length.
2. Hold in the trigger and approach the FLP. The signal strength will be positive and will increase. Note
that the target appears in the top left corner of the display, and the target gets closer to the box
(locating icon) as you walk toward the FLP.
