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 guidance 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.
1. To determine your desired HAG distance, hold the receiver comfortably at your side, maintaining 20
cm 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.
2. From the Main menu, select HAG. The HAG menu displays with Enable HAG highlighted and the
current or 0.51 m default HAG setting shown in the description line at the bottom of the screen. If
the HAG had been enabled, Disable HAG would be highlighted.
