Locate Active Signals

CMW

Technique

1. Facing away from the transmitter, walk in an arc approximately 25’ (A, 7.5 m) around transmitter, as

shown above.

2. Rotate the receiver and observe the screen:

• Target is located where signal response

(1) is strongest. Signal strength is shown

graphically as well as numerically.

• Adjust gain as needed to maintain signal

strength. Gain is shown graphically as

well as numerically (6).

• The Compass Line (2) shows the direction

the cable runs.

• Move in the direction of the center arrows.

When the arrows form a diamond (3), the

target is located.

• AutoDepth reading (4) will appear when

target is correctly located. If operating in

Manual depth mode, press and hold the

Depth button.

• Use Current Measurement (5) to identify target cable. Current on the target cable should be higher

than current on another cable that is picking up signal inductively from target cable.

3. Continue to trace the cable and observe depth estimates every few paces.

4. Retrace the cable and mark with appropriate flags or paint.

IMPORTANT: Follow steps below for all types of active location. For reference, the illustration above

shows direct connection method. If using broadcast induction, ensure that transmitter is in line with and

above suspected cable, as shown on previous page.
