from the ground.
Note: This 6-inch (15.2 cm) rise must be exact for the depth reading to be accurate.
A suggestion is to utilize a 6 inch (15.2 cm) piece of plastic pipe or wood as a spacer
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
