Thanks to the guy that posted the Nail test. This test puts a dime just inside two nails and using an Etrac he picks them up every pass. This is great because the conductive number is very consistent. I knew I was picking up good targets out of Nails but I had to be sure. So i did the Nail test with a Clad dime. I did not pick it up at all with two large Galvanized Nails so I switched and I got two smaller Roofing Nails. Because of the Heads I thought these would be harder to pick up. Picked up the Dime every time. I am set ferrous open to 23 and got the reading of 19 or 20 and 43 every pass. I was good to go when I noticed something else.
As I picked up my Coil and wiggled it back and forth nearly every time at some point I was able to get either a perfect reading of 12 43 or close 11 43. This was as I pulled away from the target. I am using a Coiltek 10X5 coil so I am not sure this will work with a larger coil but this will be an excellent way to check ID on a coin.
I am thinking this works due to the tendency of the Coils picking up targets in a V directly under the coil and at some point the Nails are stopped from blending their ferrous number.
just one more tool for the bag.
