Pin-Pointing the Sonde

Note: The receiver handle must be oriented perpendicular to the sonde. The cross bar of the receiver must be in line with the sonde (the opposite of line locating).

1.Set the receiver to Sonde mode by pressing the Sonde key until the frequency of the sonde appears on the locate screen.

2.Holding the receiver perpendicular to the suspected path, walk the path until the receiver detects the first peak signal of the sonde.

3.Adjust the gain down if the bar graph closes completely.

4.Continue to walk the path. Observe the response of the receiver as the center (and strongest) peak of the sonde’s magnetic field is detected.

5.Continue past this strong peak. The signal will fall and then rise again as the last weak peak is detected.

6.Retrace your steps, watching the receiver.

7.The sonde has been pinpointed when the center of the strongest peak has been found.

8.Measure the depth of the sonde by placing the tip of the receiver on the ground and pressing the depth key. Refer to receiver set up section to select “snapshot” of “live” depth modes.
