So a buddy and I went out and did some shooting in the woods, and he brought along a metal detector. He got there an hour early and did some prospecting for old junk, hoping to find Civil War bullets in particular.
He didn't find anything. I asked him about his metal detector and how it worked. He described it for me and told me about the different numbers that would come up on the digital display when he passed the end over buried metal.
As a test, I drew my Kel-Tec P3AT,
fully loaded in magazine and chamber, and tossed it on the ground. I said
"why don't you show me how that works; pass the metal detector in the air a few inches above the ground and let's see what sound it makes and what numbers show on the display when you cross over the gun."
Well, he did that with the circular end of his scanner being only about 7 or 8 inches above the ground, nothing between his machine and my pistol except that air space. His detector barely made a small noise when it went over my pistol.
Then he said the digital display showed .4 and he doesn't normally dig if the reading is that low --he digs when he finds the numbers go up to .7 or .8.
