Did any of you, while using an MFD, ever have it lead you to a different metal than that which you are looking for. For example, if you had the MFD selected to gold, lets say 5k hz, and the rods took you to a hunk of iron?

Yes many times :frown:

Almost 99.999% of times the unit detects some thing else:D

Yes, this is a problem with buried metals
Frequency varies in buried metals
Relative to nmr of metals outside the soil
Due to the change of the metal shell layer over time
The molecular nature of the metal layer changes
Now you have to make some changes to the metal search
To get the best results :)

Thanks Reza Vir, Very interesting. From your knowledge and experience, would there be a recommendation in the variation of 8.7k hz in a mfd configuration in the survey for some Spanish silver in a marine sandy soil environment? Buried app 150 yrs.

Hi thanks for the answer
I found silver and gold with many devices
But none were the same frequency
I know the environment and the magnet field are different in every place
And these fields affect the frequency changes of gold and silver
I put the silver ring in the same place
Switches with different devices
I found myself in all the frequency bands
You have to sample and then find the sample
Use old silver bruise
Frequency varies in your location

During times of solar magnetic interference the frequency driven locators can be totally off on discrimination.

Normal times, I can put on 1lb. lead ingot out and the Contraption will not respond to it, but to the gold or whatever test target I have it set for.

Unless i set it for lead.
