Wow, this coil is hot on silver,copper and brass. I worked the old homestead again. Posted the junk pic. Lots of copper and brass junk, and a marble! I think marbles are the best omen for a good hunt, shows activity and kids, both mean silver! This is by no means all of the junk, I didn't include any of the giant iron chunks. Also I found about 5 samples of the copper wire in the photo.

I parked in the field about 50 yards from where the old home sat. I worked my way up to the homesite, and dug the normal junk. The 3 khz coil seems to either null iron or give a solid 46, not much jumping around. About an 1/2 hour into the hunt, I hit the quarter. It was about 5 inches down, and id'ed at 42. No mistaking it was a coin, I had a feeling it could have been an aluminum can by how much the machine was popping off, but the id or tone did not waiver.

My uncle pulled up to see how I was making out, and he gave me a better layout of the farmhouse and were the barns once stood. Shortly after I found the merc, where the front yard would be. Again, a hot signal. This coin was about 6 inches and it popped off like a clad quarter on the surface.

I was digging any reasonable signals, but what I am finding is all my keepers (and junk made of keeper material) are solid repeatable tones, regardless of what the id says. Iron will give the broken up tones, jumping from low to high. I am using four tones.
I found the best way to determine if it is made of coin material is the simple coil shake. So far if it has been brass, silver, or copper, I have found that if you put the coil over a potential target and don't move it, you will get some response. A simple shake from side to side will tell you what you have. If it locks on to a target number, I dig, and it will be a desirable metal. If the target nulls, or jumps around, it has always been iron, or a hot rock. Also, a signal from a desirable metal doesn't "move". By "move" I mean that a "44" number doesn't seem to id on one spot, then move an inch over, etc. The desirable metal targets always stay put.
So I was detecting about an hour, and started back to my car. I hit a super solid tone. Dug down about a foot and found an old style Budweiser Can. The only other junk I find at this farm are Pepsi Screwtops, because they used to have a machine, and everyone threw the tops out to the tractors. I know, I worked there 20 years ago. A little further down another solid target, seem to strong to be a coin, but dug anyway. I hit the top of a pipe about a foot down that still seem to be connected to something. It would no budge so I let it be.
About 10 feet in front of my car, I hit a solid 42. No mistaking this hit, it had to be something significant. No hot rocks or iron on this signal. Then I dug the sterling pen knife. I didn't damage it, it must have been gone over a time or two with a cut harrow. I have found some nice coins, including a US half dime, but if this item wasn't damaged, it would have been my best find so far.

In the junk photo is a clump of whitish stuff, which is a glob of lead. I also dug bits of lead that are a pain in the arse, to identify and sort out of the soil.
This coil is definitely hot on silver, copper, and brass. It does not lock onto iron like the 7.5 and 18.75. Iron either nulls or large pieces lock on at "46". I think the coil is ideal for farm field hunts. I want to try it at a local park and see how it handles large amounts of pop tops and aluminum junk.
