[BENZINAS]

Hi , i'm looking for a cave finder detector patent , small device and tested from forum member working good , all ideas accepted , or if there is a device on ebay working similar as a cave detector tell me !

If you are asking for "small device", then you need to search for so called "magnetic locator".

Mentioned devices are small, relatively cheap (starting from $500) and accurate cave locator's:

Thank you

we can calibrate it on gold frequency with bilateral switch . what do you think ?

[Geo]

No........
Gold has not a "standard" frequency. NMR is depended from earth magnetic field and it is very very low, not able to measuring via normal meters...
