Default Iron scans as Silver

I got permission to Detect a property first built upon in 1790. I don't believe it has been detected before. *fist pump*

Here's the rub...

The site is littered with nothing but Nails. (Most of these nails are newish but a few are square.) The iron always reads as Silver. The nails in the ground read solidly as 88-98 on my DFX and can pin the needle on the 6000 Di Pro SL. I have found as many as 4 Nails in a single hole as deep as 10 inches. The pistol probe goes nuts on every setting except on minimal threshold. There's that much iron.

I am going to work this site all summer if I have to. I know there is good stuff there, but I need to weed out the iron first. Is there a better way than merely digging all these nails up bit by bit?

Other than a huge magnet, I don't know.

I am curious as to why these nails ring like silver. Could it be the density of the nails that increase it's conductivity?

I have had the same thing happen, nails ring as a coin. Not certain why.

Day Two.

I have a little under a pound of iron at this point. My discrimination is turned all the way up. Who knows what I'm missing but it doesn't matter because the only signal I can get is strong silver. The nails above ground read as nails. Other than the nails, the soil is a pleasure to dig in. Sandy soil and no rocks to speak of. The only thing that is about as common as the nails is pieces of coal with bits of old porcelain thrown in for good measure. The farther I get away from the house the fewer hits (nails) there are. I am beginning to think a carriage house or small barn behind the house burnt down. This might explain the nails, but not the faulty readings.

Well... back at it I guess.

I wouldn't crank up the disc, just evaluate each target as it comes... I get the same effect on my x terra 705, it's amazing where iron will read sometimes... It's alot slower, but you won't miss anything like say gold...

Sound advice.

A few days ago at this same site, I got a good mid 80's tone. I rolled my eyes and then my sleeves and got to digging...

2 Nails and a 64' Jefferson nickel in the same 4x5 hole. Progress. Not staggering, but progress none the less.

First (barely) silver of the year for me.
