Well, back to the topic The Viking needs some kind of ground balance. I was looking at a Whites Beachcomber 6.0, which has some possibility to either GB or discriminate. It has also a retune button. Anyone ever used one? Whites 3900 might be a similar circuit but with added sensitivity control.

I just wonder if a detector like that has some advantages to offer - for tiny gold jewellry hunting on a salt water beach. Not that one might get rich of it, but it is a kind of challenge for any detector as I understand it.
