GROUND______________________________ 

With this control you can correct ground effects 

and more accurately reject ferrous minerals or any 

pottery containing iron oxides.

If you are prospecting on grounds loaded with 

magnetic stones, it might be a good idea to keep 

a sample of these stones on you to adjust your detector before 

detecting this type of ground. You only need to move a magnetic 

stone in front of the search coil turning slowly the GROUND 

control from left to right so as to obtain a total rejection of the 

stone. 

If the mineralization is too scattered, sweep the head on the 

ground and turn the control progressively from left to right in 

order to get good stable detector. On mineralised grounds, these 

procedures will optimise your searches.  

For maximum depth detection, do not turn this setting 

towards the right more than necessary. The red arrow 

indicates a basic position suitable for most  ground.
