My Elite 2200 sure can not.

Most of today's MT's will allow you to discriminate in a certain range of the conductive order of metals. I am not sure, but if you have a dial type of discriminating MT, it works kinda like the squelch on a CB radio filtering out anything under a certain threshold. Say you don't want pull tabs which is about 25 in the conductive order of metals. Then anything under 25 won't register. You could overlook something. Like I said. I am not sure.

Today's MT's will discriminate about a +/- 5% percent of a given metal category. This way, if you don't want to find iron, or pull tabs, but wants to find metals who are lower in the detecting range, you can find them.

I don't know about the Elite 2200. But I would think it has computer based discriminating.

Drummerman:

The Elite 2200 has the ability to discriminate iron, then PT/nickels, then PT, then s-caps (screw caps), then zinc. It can discriminate all or any combination of those. The problem is that when the good target is so close to the iron, that the iron discrimination overpowers the overall system and the good target is ignored.

Try your machine. Place a gold ring on a wrench and sweep it with iron discriminated-out and report your findings back on this forum please.

You are correct. Even wt a small/medium rusty nail and a dime held tightly together(centered) and waved under the coil. The 2200 will read it as iron in all metal and almost eliminate it wt iron notched out. All my test Im waving items at about 3-4 inches from coil. It will pick the dime up if right on coil,but still effected.
As you move the dime ofset from center of the nail it starts to give a better reading. But must be at least 1/2 to 3/4 of an inch away b4 start getting a reading above iron.Anything at 3/4" or after starts to get a good reading but is affected.

The nail I used looks like about a 8 and rusty.
I believe,, when these 2 items are in the ground, the signal gets better for us ,b4 it gets worse. Halo effect and all that makes the dime bigger and the nail smaller,or maybe both together gives a better reading than the air test. I say this because I have dug allot of coins wt things in the hole wt them, and got a decent enough reading to dig. But there is no way to tell how far apart they were b4 digging. (seemed they were on top of each other)

Thanks for the refresher, I will keep this in mind next time I am cleaning out an area wt good coins.

I am now interested what machines will pick up the a dime with this test. If any????

A digital type detector (one without a true DISC Knob) will probably not do this, but a detector such as the BH Land Star just might...When I get mine back, I will test it out and post here...
Detector must also have a decent recovery speed I would think...

I will try it out tonight if I get the time. I'll let you know as soon as I can.

My Land Star should be on my porch Tomorow, from First Texas (they retuned it at the least) by 4pm EST...I will try it in my back yard if I can find a clean spot...

HH,

We just tried this test,same nail and dime I used, wt a garret 2500 in jewelry mode(i think) it would not pick up the dime until seperated by at least 2".

I didnt realize how much effect a nail like this causes. Makes me want to go back to a few places I cleaned out. Where I found some very nice coins and start digging in all metal. lol NOT gona do it.

Good Luck

I hust got the Land Star back from the factory, and it is once again functioning...I tried this with a older large ion nail that was not so rusty, and when I DISCed out the nail, it just barely gives a low chirp, before it rings high on a dime...kinda a double sound, but the dime signal is very obviously the winner...I could not video it...sorry...

HH,

i want you to say that again. lol wt more detail

 

[drummerman]

Sorry guys. I haven't gotten around to try it yet. Got wrapped up in the Farve deal with the Vikings Tuesday, and yesterday we had some severe storms in The Twin Cities.
A small tornado touched down in south Minneapolis, and another in Cottage Grove. Cottage Grove is about 5 miles from my house. I was at work about 15 miles away. Didn't see anything.
No major damage in my area. Had a bunch of trees uprooted and and a few building were damage in south Minneapolis. No life's lost. Thank God!

We are still getting rain today. Maybe tonight it clears.

The Fisher F75 will. I know that from personal experience. With the right settings you will see enough of the dime to dig that.

As far as Bounty Hunter machines I've only used the QDII and I never tested that, but my gut feeling tells me it would probably not see the dime. Only one way to know for sure though.

 

[flash5153]

I have dug several things in the past wt the 2200 that had some rusty nails or other junk in the hole wt a coin.It gave a decent enough reading to dig them.

So when I did this test I was a little suprized to see the dime pretty much disappear when centered over the nail..

Not sure if there a difference between a new nail or rusty nail wt this test ,,,,but from post on here I am not a believer, yet ,that anyone has a machine that will pass this test.

Not saying that there is not one out there.

Theres not much we can do about this unless go to all metal and dig everything. And thats not gona happen wt me.So I guess that the coins that are sitting in the dirt ,dead center of some rusty object,,,,,,,stay in the ground.

Sometimes rusty nails give me a sharp "ping." So whey in real life you find a coin with a rusty nail, maybe the nail was talking to you and not the coin.

I know that some of the higher frequency machines will. I have done it myself with a Vaquero and Cibola using a silver dime, about clad I am not sure.
