Can your machine past the iron test

I am looking for the best metal detector to use in iron infested areas. here is the test.
Lay three nails on the ground, approx 1/4" apart.
Discriminate the nails out.
Lay a dime on top of the nails.
Will your machine id the dime.
Put the dime under the nails.
Will your machine id the dime
Try same test with different size coins.
 
It does not matter if you test on the ground, in the ground, or air test. The objective is to test you metal detector for iron masking. I am posting the same question on all forums.
 
You should tone id it easily although it will be easier swinging along the nails than across them and you may have to adjust your swinging speed for best results. Results will depend on the size and type of the nails and I wouldn't rely on the depth meter or crosshairs!

is that the nails and coin are laying on the ground or freshly buried. In actual circumstances when the coin and nails have been buried for a period of time the iron nails will have leached some of their material out into the surrounding soil and created a iron halo. When you find a unit that will consistently id the coin in that case let us all know.
 
I forgot to say that of all the units I've used the Explorer seems to come up with the most good targets with iron next to or near them.
 
Great input everybody, you are bringing up ideas that I did not think about, this is what I am looking for. People with open minds who don't mind sharing their knowldge about the detector of their choice.
 
The rust on this quarter was from a large nail. It gave a good enough signal that I dug it.

Those are some nice coins, the problem that I am having right now is that I did alot of research on locating old sites, but they have alot of small iron scattered all over the place.
I am trying to find a detector that can deal with the iron. I know that there is no perfect detector and one must choose a detector that is appropriate for the task at hand, looks like you are doing something right to find those.
 
Since you didn't say what size nails to use, well, ...............

Great Art
Tell me more, what was your settings on disc. I have been wondering if I set DISC at zero.
 
Kind of got you on that one.....
Used 3/4" 18 guage brad nails......not sufficiently large enough to cause any problems.
Landstar...disc half way up.
QXT ...coin mode
Sov....min disc
Nails this small are not sufficient in size to stop the detector from giving a good ID.
Just one large spike would be enough to wipe out anything.
Your test requires a "standard" size nail if you want to find out anything meaningful. Needs to be something that is niether too easy or totally hopeless if you want any meaningful results.

Well if you actually believe that is the same than enjoy. <img src="/metal/html/smile.gif" border=0 width=15 height=15 alt=":)">
 
It sounds like the explorer can be adjusted to handle most situations, I have been impressed by what I have read on the forums. I think that you make a good point concerning the size of the nail or iron in relation to the size of the coin. It makes since that if the coin is larger than the piece of iron that the coin would be more easley identified.

Sorry if you read this before but it is my best experience detecting with nails.
After carefully searching this site with my other machine (CZ) using both an eight inch and a four inch coil. I took the Explorer in with the big old 10.5 inch loop. This dime was missed by both my other loops but gave a nice high tone on the Explorer. I dug a three sided plug approximately 3 x 5 inches. In the middle of the hole at 4 inches was the small nail. At eight inches in the back of the hole I found the huge nail. And at six inches in the front of the hole was this nice Barber dime, 1902. I was shocked and still marvel at what this machine will do.
Listen to what the thing is telling you. HH - Robin
 
Thanks Robin
You bring up some very good points, the sizi of the search coil, size of nail, amount of time targets have been in the ground, and amount of experience of the metal detector operator. I have received alot of info from Explorer user, each using various methods to find targets.
One thing that I have learned by posting on the explorer forum is that the Explorer provide the user with a ton of information about what is under the search coil. HH TB
 
I have had good response from people using different detectors and what has surprised me is the possibilities of conditions that one might incounter at various sites. The size of the iron object in relation to the size of the coin, depth of target, and size of coil used on the detector.
Metal detectors that past the iron test, performed by people that used their own detectors are as follows.
Minelab Explorer
Garrett GTI 1500
Whites IDX with Mr. Bill's Mod's
Compass 100 Khz
GMT 1650
I am sure that there are other detectors that can pass the iron test, these are just from a small sampling.
My post was intended to address one specific area of metal detecting, not in any way to prove that one brand of metal detector is better or worse than the other brand. TB
 
The Detector you want currently being produced is a Hays Mark 1 and 2.

A straight TR operating at 100 kHz. Will see through most iron nails and hear the non-ferrous, dime etc.
 
I think Art said it best as you are not duplicating a coin or nail in the ground scenario. Dial in swing speed, your ground conditions in your area, type of coil, set up of unit or just plain ability of the user.
Still haven't figured out if your looking for a fast recovery machine or a slow recovery that works in these areas..
Having found nails in holes and coins in the same hole with this Being an Explorer Forum. I do know Minelab handles the situation well. And these are not ball park results but actual in the field hunt situations.
Now if you looking for a fast recovery unit perhaps one of the other forums can help you and must say two oldies but goodies come to mind in the GMT 1650 or King Cobra which haven't been made in years.
