To calibrate the receiver:

1. Using a tape measure, place the receiver on the ground parallel to the transmitter (in housing) so that

the distance from the centerline of the transmitter to the inside edge of the receiver is 10 ft (3.05 m),

as shown in the figure given below.

Setup for 1-Point Calibration

2. Hold the trigger in on the receiver, and verify that roll and pitch readings are present and that the

signal strength is stable. Then, click the trigger to advance to the 1-point calibration screen.

3. Hold the trigger in while holding the receiver steady through the countdown sequence from 5 to 0.

4. When the counter reaches 0, continue holding in the trigger until you see a checkmark at the bottom

of the display indicating a successful calibration. If you see a checkmark with a slash, then the cali-

bration has failed, and you must repeat steps 1 through 4.

5. After you have successfully calibrated the receiver, you will be returned to the standard locating mode

screen. You must now verify the calibration by checking depth readings at three locations.

6. To verify calibration, place the receiver on the ground parallel to the transmitter so that the distance

from the centerline of the transmitter to the inside edge of the receiver measures a given amount on

the tape measure; in the example shown in the figure below, a distance of 6 ft (1.83 m) is used.
