Operator's Manual
Use AGR at least daily, and ideally in both frequency bands, to verify proper depth/distance measurements.
1. AGR
2. Pitch assumed zero
3. 15 m calibration
Above Ground Range (AGR)
If you just completed AGR after calibration, don't forget to turn
Height-Above-Ground (HAG) back on, if necessary.

15 m 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 12.2 m 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 Height-Above-Ground (HAG) to set a height measurement on the receiver so you don’t have to set it
on the ground for a depth reading. Raising the receiver above the ground also provides separation from
underground interference that might otherwise 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 Target Steering and AGR
tests. Until you enable HAG, the receiver must be placed on the
ground for accurate depth readings.

Prior to enabling HAG, verify accurate range/depth readings at a minimum of two points using AGR
(see link above) 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.
