I've not had any problems with Gradiometer surveys but I have seen a magnotometer miss a Roman pottery kiln lying just below the surface. My experience is that it can be a bit pot luck with G Fizz, but the positive results are well worth the occassional poor one.
When I look at the smiles on all the children's faces, I just know they're about to jab me with something.
