Discrimination

[Anonymous]

This is what I mean when I say we can double our discrimination by how we swing the coil. Coins in particular will for the most part have a consistent sound. I think this is due to the symmetrical designed of a coil and also that the metal. Those big irregular shaped sounds with a bunch of tones are not going to be a coin. If there is a consistent coin sound mixed in that can be isolated then there may a coin co-located with some other metal. There are not enough of these to make it worth the bother in my opinion. Consistent low tones are a sure sign of iron and that iron can be detected before the target comes under the edge of the coil. Coins start to sound when the coin is under the coil but that is not the first thing I look for. It is the size of the target and don

After three years I still cannot tell the difference between a coin mixed with iron and iron falsing. Not 100%. And deep coins not colocated with iron can also sound much the same. Having said this there are definitely times that I have much higher confidence that there is something good in the hole. But I've dug enough that I though were low probability hits that turned out good. And these are often the older coins. I have a periscope probe and that helps greatly, I can probe before cutting a plug. Much of the time if it is an iffy hit and the probe says iron I will move on. Occasionally will dig and remove the iron and rescan if I think it sound particularily good. Very often it will turn out to be a square nail and nothing good. But.. enough of the time, at least in my book, it is a coin. All depends on the area, my mood, and etc.
I'm absolutely positive that we still leave many coins in the ground because of trash masking. Many time when I find one coin I will hit the area from many angles and dig stuff I would normally ignore and come out with good stuff. No way you could do this with every hit or you would die of old age before finishing one lawn. Its all probability and what you are in the mood to try.

I don't think there is a way to get it all unless we dig up all the dirt and sift it. These remarks, the programs I post, are all just to say this is where it is today knowing it will change. As an example at the beach I would hunt different then on dry land and hunt areas that are very rocky and hard to dig different than those areas where it is easy.
