Check for the absence of magnetic objects by moving the device along your body (holding
gradiometer vertical to the ground).

If necessary, select new parameters for operation. Use button 1 to switch to "MENU" and choose
the desired backlight, brightness, and contrast. Remember that with backlight turned on, battery
time will be 5% less. Switch to "Sound regulation" and select the desired volume and sound
threshold (default setting 10 units for sensitivity level 1, and 2 units for sensitivity level 0.1). If
needed choose appropriate "Filtering" and "Correction of "0". To save the selected settings for the
following sessions, exit each parameter by pressing "OK".
Leave the device in "Operation" mode for 20 minutes to warm up all electronics and sensors.
After warm up is complete check settings for "Balancing" and "Alignment". To do this pick a spot
with weak magnetic field gradient (no more than 2-3 units). Perform demagnetization with button 2
← and reset readings to "0" with button 7.
First check balancing of sensors: turn to face North, reset readings to "0" (button 7), and tilt the top
part of the gradiometer 3-5 degrees to the North, then to the South. Make sure the measurements
do not change by more than 5-10 units, or remain at the level that will not interfere with search (no
more than 5 units).
Now check alignment of the sensors: holding the device vertically (without tilting) turn to the North,
East, South, and West. Make sure the changes in readings are small enough not to interfere with the
search.
If necessary perform "Alignment" and "Balancing" tuning procedures as described in Part 4 of the
manual. If no tuning is necessary, you can begin work.

Begin search: Stand at the beginning of the route, reset to "0" with button 7 and start moving.
During movement you can change without switching to "MENU" the following – sensitivity, filtering,
sound volume, correction of "0".
5
During movement try to always hold the device vertically without tilting and turning. If you turn
abruptly the device may register a small constant level of magnetic field caused by poor alignment
tuning. Simply reset it by pressing button 7 on the handle and continue movement.
Movement can be performed at any speed allowing to hold the device vertically.
It is better to search the area along parallel routes. The distance between the routes is determined
by the size of the expected anomaly that you are searching for. The routes must guarantee crossing
the anomaly at least twice. For example, if the needed anomaly is approximately 4 meters (12 feet),
the distance between routes must be no more than 2 meters (6 feet). To guarantee quality of
