Country, regarding the use of metal detectors. Be respectful of public and 
private property, and the laws, which govern the use of metal detectors, and fill 
all holes after recoveries. 

Troubleshooting 

My unit does not maintain its ground balance. 
Check the battery. In most cases an undercharged battery will cause this to 
happen. 
- or – 
There could be spots of mineral content that you are trying to balance device 
over. 
- or – 
When balancing unit you are holding the unit too high off the ground, or 
directly on the ground. Hold coil 12”–16” (25cm to 35cm) above ground to 
balance initially. 

I found a metal object, re-tuned my detector, now it is gone. Why?
You re-tuned the detector while still in the field of the metal target. You have 
discriminated out the target you were looking for. 

I cannot get the unit ground balanced. 
Adjust the Interference. It is possible that you are too close to an electrical 
source and the source will have to be tuned out by turning the knob either to the 
left or the right. 

My battery connection keeps coming loose. 
With battery disconnected, open the two prongs on the control unit to allow for 
better battery contact. 

It beeps and there is no target. Why?
Minerals with round and square coil are patchy sound and usually are not 
identifiable more than twice. 

Technical Specifications:

• Working Voltage 12v DC 
• Continuous Power Consumption 190mA 
• Maximum Power Consumption 380mA 
• Working Frequency 100-130Hz 
• Sound Range 0-10000Hz
