Step 2. Press DEPTH [4].

− The display will instruct the operator to raise the unit 6 inches (15.2 cm)

from the ground.

Note: This 6-inch (15.2 cm) rise must be exact for the depth reading to be accurate.

between the ground and the tip of the receiver for this precise measurement.

Step 3. Raise the receiver 6 inches (15.2 cm). Press

the DEPTH [4] key again. The estimated
