So the rods don't work as claimed !?
Well... I saw some people find 50cmx50cm area with target... from far, more than 30meters also.... in open field, few metal buried...
Then use conventional MD to pinpoint.
In one of these places I run one of my old vlfs and found very few metal stuff... they use rods and locate rusted stuff! unbelivable!
I don't know about... maybe something exist for real , tested myself and found no usefulness in rods... but in their hands things are different.
But, sure, don't make any double blind test...
Kind regards,
Max
