Hi Helmetfire I'm sure that Annubis has the definitive answer for you but my take on the situation is:Helmetfire wrote:Very useful thanks.
One question though.
You say in 'Option 1' to "ignore the low buzz, it's iron", but I have found that Gold also gives a very low tone/buzz... Am I misunderstanding something?
It's possible you have the 'Iron Threshold' set a little too high for the detector to give a mid-tone response to gold. This I understand is because the conductivity of gold is low down on the conductivity scale pretty near iron.
Having sais that, you would almost certainly have had a repeatable two-way signal and even if that is accompanied by a 'buzz' it must be dug for the reasons outlined above. If this practice is adopted, that buzzing signal, that is repeatable may well produce dividends. Low grade bronzes are sometimes responsible for such a reading too. Cheers and all the best. The Goldmax is a winner in my opinion.
