50 Foot Calibration (Optional)
This feature is primarily used for demonstrations of the locating system above ground and is
not necessary for drilling. Above ground range (AGR) measurements beyond 40 ft. often read
shallower (shorter) than they actually are due to variations in ground conditions, and this
feature calibrates these measurements to account for these variations. Using this feature is
substantially similar to the procedure described for 1 pt calibration; if you require further
information, please contact DCI customer service.
Height-Above-Ground (HAG)
Use HAG to set a height measurement on the receiver so you don’t have to set
the receiver on the ground for a depth reading. Raising the receiver above the ground also
provides separation from underground interference, which can reduce the transmitter’s range
or cause variable readings.
To prevent incorrect readings, Falcon F5 always powers on with the
HAG function off (disabled). HAG also automatically shuts off during
calibration and is ignored during an AGR test and Target Steering.
Until you enable HAG, the receiver must be placed on the ground for
accurate depth readings.

Warning Prior to enabling HAG, verify accurate range/depth readings
at a minimum of two points using AGR or a regular depth
reading (hold the trigger). If the transmitter is not properly
calibrated, inaccurate depth readings will be made worse by
an inaccurate HAG distance.

1. To determine your desired HAG distance, hold the receiver comfortably at your side,
maintaining 8 in. of separation from the front of the receiver to your torso as specified in
the Safety section on page 1. Measure the distance from the bottom of the receiver to the
ground.
