Lower ID numbers question...

[NealNoIN]

I know iron ID's below 40 but I was wondering what is in the 35-39 range? Can I expect this to be all iron too?
Maybe some real small foil???

Well, get some small items and scraps and wave them under the coil to see what they ID as. Ocassionally I go back to my wifes jewelry box and test the really small earings, backings, etc. Some of the gold items with a steel pin in them will ID very low.

Just ran all of the gold rings I have found past the Gold Bug (Standard digital) and they fell within the range of 45 to 82 with a large portion being in the 45 to 55 range.
A dozen or so gold nuggets in weight from 0.2g to 1.75g signaled in the 48 to 55 range. Several light weight 9 and 18kt gold chains signaled from 42 to 52

In the ground it is different especially mineralized ground. I have had very small jewelry like earring backs fall in below 40 But nothing good below 34 for me. By good I mean small silver or gold. Once onto the gram size and up if getting a clean ID will not fall below 40. In real heavy black sands all sub gram targets might as well be invisible. The Black sand beaches here runs 41 to 44 on my meter and overloads the g2 with any kind of gain enough to get small gold jewelry.

When people make a reference to the type of ground make-up they have where they are, they often forget to tell us just where they are, and that info can help.

Very correct reply, by the way.

I have found that nugget hunting in tailings that the target ID number on my GoldBug Pro is only one piece of puzzle in identifying targets. For example I have a quartz/gold specimen I carry with me in the field that weighs approximately 35 grams total and through specific gravity testing I estimate it contains about 6 - 7 grams of gold. Air testing this piece will give strong signal and a solid reading of 47-48 at over 12". In ground will low mineralization I get approximately the same depth but the signal will bounce around a bit but still reads mostly in the 47-48 range. However I have tested it in areas where in the ground i get a strong loud signal but the ID is only 27-30 and sounds virtually identical to an iron nail. When mixed among hot rocks sometimes the ID will be low to mid 20's. I have also experimented with watching the Iron indicator along with the target ID to see if I could improve my ability to ID without digging and in some cases, particularly when you have a very strong signal it clearly helps but is not always definitive. After discovering this I have gone back to areas that have been hit hard and that I had previously covered and reworked them digging every target. I dug a lot of trash but was also rewarded with some nice pieces. To add the the puzzle I have found that this same test piece will read significantly different with each of the the 3 coils I use depending on the conditions.

Hi Monte,

That would be certain Tahoe beaches. And its not the whole beach that is black sand but multiple lenses. You may see solid black patches on the surface and clean sand in other areas but when you dig in the sand layers are zebra striped.( quite beautiful) I know there is stuff in there and I've found shallow targets but I can only punch in about 3 inches and that's with a different machine. Popular beach with allot of weddings in the summer;

Hey Tabman,

Nice chain, Have you stretched it out and checked it. it seems that for me the chains I have found I have hit the clasp only except on bracelets. Its good training to hear them that way. And in different configurations on the ground.
