D. Induction Peak (Ind Pk)

Locate/OK [5] + Cable/Pipe [SK] + Mode [SK] + Ind Pk [SK Toggle]

If you cannot make a direct connection, or use the 3M

™ 

Dyna-Coupler Clamp to apply 

a locating signal on the target, use the induction method. This method uses the internal 

coil of the transmitter to generate a magnetic field.
The Induction Peak mode of the receiver is a mode in which the upper antenna of the 

receiver is tuned to minimize distortion from the magnetic field of the transmitter.

Left or Right of Target Path

Directly Over Target Path

E. Expanded Mode

When the third ring of the speaker icon is dotted 

or broken and ‘xpnd’ appears below the speaker 

icon as shown, the receiver is in “Expanded” 

mode. This mode is used for pinpointing a 

target cable or pipe. The area of response of 

the receiver narrows, allowing the locator to 

detect very small signal changes. Press the 

Speaker Volume Control [2] key to activate the 

"Expanded" mode.

Verifying the target path, depth and current can be helpful tools.
1.  Pinpoint the cable or pipe being located.

2.  Lower the tip of the receiver to the ground and 

press Depth [SK].

 

− The depth to the target cable or pipe is 

displayed in the units specified in the receiver 

set up menu. The bold current reading is a 

relative current measurement. This reading 

can be compared to the current reading that 

alternately flashes with the frequency on the 

transmitter to help identify the target cable/

pipe. The highest relative current value will 

be the target cable/pipe and will compare 

closest to the transmitter relative current value. 

The milliamp reading is an actual current 

measurement.
