1)

 

Before detection every time,  you should press Red Button to adjust balance, 
release  the  button  when detecting,  you should  not press the Red Button  while 
detecting. 

2)

 

The volume  should  be adjusted  so that you can  hear the sound,  not adjust it too 
loud.  Normal volume is most productive when trying to differentiate between 
sounds. 

3)

 

In areas with heavy traffic, please don’t wear earphone, in case an accident occurs. 

4)

 

Always obtain permission before searching any site. 

5)

 

Keep away from the region that may bury electrical line, cable line or pipeline, in 
particular the pipes that are full of flammable gases and liquids. 

6)

 

Do no detect in the military area that may be bombs or gas explosives. 

7)

 

When digging out the target,  use  a  reasonable method,  do not destroy the 
vegetation. Leave the land and vegetation as it was after excavation. 

8)

 

When using earphone, don’t set it too loud, this may damage your hearing. 

 
 

Trouble Shooting Guide

 

SYMPTOM 

SOLUTION

 

No power   

1.Be sure that the polarity of batteries are 
installed correctly. 
2.Replace the batteries. 

The unit is silent when turns on,  and the 
meter pointer doesn’t move,  it seems 
there is no electricity. 

The balance has a deviation.  Press the 
Red Button, and adjust the TUNE knob to 
let the detector be in balance state. 

Sound an irregular tone. 

1.Make sure there is no other metal 
detector operating around. 
2.Don’t use it indoors,  because there are 
many metals there. 
3.Make sure whether there  are no 
electromagnetic interference sources, 
such as power lines,  cables,  electronic 
fences and so on.  Keep away from these 
areas. 
4.The ground may be  magnetized  due to 
soil composition present.
