two coins & a sore elbow

[fongu]

I got to do a little metal detecting yesterday and found a 1991 & 1973 penney and a lot of junk. Why do rusted nails register as coin? Really paid the price for going metal detecting with a sore elbow. I have developed a spur from an injury back in 1995 and I guess the doctor is gonna have to give me something for it. Can't even swing a detector today. Why does old rusted metal have such a high conductivity rating? Just curious. Rusted metal and nails always sound like a coin to me and the nails register as a B target.
My spending some extra time with my GTI-2500 is paying off because I can easily tell when there are two and sometimes three targets under the coil. I dug up a small piece of metal that looked like a key for a pump mount and then a small screw and finally a small piece of rusted wire from the same hole. The small piece of wire was hard to find, but the propointer finally helped me find it. Without the propointer I would probably still be trying to sort it out. It is the best little tool in the world.

I have that trouble with my 1500... Im still
learing all the ins and outs of using it

Like you im gettin a bit better at seeing
multiple targets...Most of the time !!!

I feel for ya with the elbow. I've had 2 surgeries on my left one and it's still close to useless. Had to learn to do everything for detecting with the right arm only. Makes it a bit slower and can't stay out for long, but at least I still can go out.

The nails are chiming in as coins because as they disintegrate the metal content spreads out and is perceived as a larger object(?). At least that is what I have been hearing from others.

Yeah they form a halo just like a coin. Rust pockets react the same way and they explain a lot of those "phantom" signals you can't find because when you dig you destroy the pocket.

I'm lucky in that respect as I'm ambidextrous and it's normal for me to switch back and forth. In fact I swing more with my left arm than I do with my right. My mom was born left handed but back in her day you were considered to be a freak if left handed so her teachers would whip her hands with a ruler if they caught her writing or doing anything left handed. Strange how stupid people are and were and the warped ideas they adhered to.

Sorry to hear about your Mom, Uncle Willy. Human beings possess the ability to justify cruelty to one another. Thanks everybody for the good tips. If I want to do any metal detecting, I will have to find someone to help me dig, I guess. Really in a lot of pain right now, but hoping to see a doctor in the next week or two. I have ran into some of those phantom signals at this old home site and thought I was just doing something wrong or picking up a signal from something within a few feet of my coil.

I'm right handed but I swing with the left and dig with the right, I get a sore right elbow from digging, I think it is because my Lesche digging tool has been designed for left handed people. The grooves in the blade are on the wrong side for right handeds, as you have to push it in against the opposite of your natural direction, to cut the grass.

Hope you're feeling better fongu and all the best

I live in an old neighborhood and have been digging at a couple houses around here. In the last two weeks I bet I've dug up 150 rusty nails and every one registered as a dime or a quarter. I like the 'rust halo' theory cause I've wondered that myself. Doesnt sound like there is any way to avoid it. Just grit your teeth and continue to dig.
