Rough search
Hold the device at a 45° angle to the ground surface and scan the ground area to be examined in a
zigzag pattern. (Fig. 7)
Ensure even ground clearance!
Detailed search
If a ferromagnetic item is recognised, the device must be held vertically to the ground surface and the
center of the item determined using short, crossing movements. (Fig. 8)
ITEM RECOGNITION
Visual LCD display
The value displayed between 0 an 99 enables conclusions to be drawn regarding location depth,
distance and size of the item detected. This value is displayed both as a bar diagram and as a
numerical value. (Fig. 9)
Acoustic display
Similar to the visual display, the acoustic loudspeaker signal changes too. The low standard tone's
level and volume change if a ferromagnetic item is detected.
Blanking undesired items
When searching for ferromagnetic items in the vicinity of metallic fencing, iron bars, reinforced
steel walls, vehicles, railway tracks etc, they must be suppressed.
Suppression and showing are activated takes place by using the "Erase" switch.
The signals created by the undesired item are thus regulated to the value "0".
Control system
The volume and sensitivity can be adjusted using the "PLUS –MINUS" key:
"Sensitivity" = signal intensity
"Volume" = loudness
