Troubleshooting 
 

SYMPTOM 

SOLUTION

 

No power, there is no indication on the 
LCD display, there is no sound when 
powering on 

1.Be sure batteries are installed correctly. 
2.Be sure battery cover is closed correctly. 
3.Replace the batteries. 

Sound heard is an irregular tone, or the 
target identification cursor chatters / 
distorts 

Make sure there are no electromagnetic interference sources 
present, such as power lines, cables, electronic fences, etc.   
Keep away from areas that are prone to cause interference or 
you can reduce the detector's sensitivity. 

The signal is unstable and the position 
of the target identification cursor is 
changing 

1.Scan at a different angle, in order to determine whether you 
can get a more stable signal. 
2.If the target is buried deeply, you could try to increase the 
sensitivity or speed up the search coil scanning speed, hovering 
over the designated area.    . 
3.Maybe more than one metal targets are buried, you could try 
to increase the sensitivity or set different discrimination ranges 
when scanning. 
4.Maybe you found a severely oxidated target, or the ground 
contains some type of magnetic field or mineralized content. 
Attempt to decrease the sensitivity and continue scanning. 

Using PINPOINT mode. when 
approaching the ground, the unit 
automatically sounds a tone 

1.The soil is magnetic, Press the PINPOINT button again, and 
reduce the sensitivity -- and scan the area again. 
2.There are large metal objects under the ground.
