3d Dime Rusty Nail Test

[mh9162013]

This is all very intriguing. I have a proposition:

If someone in the USA has a 6" and/or 10x5 coil they can send me, I'll run them (along with my 11" stock coil) on my Modified Monte's Nail Board and report back with results. Then when testing is done, I'll return the coils on my dime (hahaha, punny).

That’s why I have my small coils. I still use the larger ones when ground coverage or depth are my main concern but the 5X10 is on the equinox most of the time. 
Like you said there are just so many different scenarios in the ground it would be impossible to duplicate them and they’re  “in the ground “ verses air tests. I think there’s a lot more to that than we know.

I agree, but maybe we can get a better understanding? Because spending another $100-$250 on a coil for target separation that's only better "most" of the time is a bit unnerving.

I know I'm not the only one with limited funds and if I had $150 or w/e to spend and I'm trying to decide b/w Steve's S-shaft or a 6" coil, I'd like to better understand what sort of benefit I'm getting with the smaller coil.

I would like to talk a little more about the test. The deus1 did hit the target with a two way swing and the equinox would only hit it one way until I stopped and wiggled it over the dime. The good tone and numbers would cause me to try and zero in on the target.
 The equinox gave the better vdi numbers but having said that now knowing what numbers the D1 gives when locating a target in close proximity of iron I’ll be digging those signals.      Before the 01’s and 02’s I always wrote off as big iron and will still do that but the 04’s and higher where I can distinguish two targets I’ll be digging. I guess I don’t care what numbers the machine is giving so long as it’s telling me to dig and both machines told me that.

I have the 10x5 on my 600 all the time. Recently I dug a small silver ring that was 8-10" deep in a hole with a few iron bits, probably old nails. Had to use the Quest pinpointer to find it. It was the 27 in one direction that clued it was there. I did not find this with the 11". I also find I have better "lock on" capability over multiple targets, probably due to learned coordination using it. These are areas I went over with the 11". I have found every silver item with the 10x5 in this place. 3 silver quarters, a Walker Half, two rings. There is a lot of iron and aluminum trash.

Hopefully the D2 and the Legend will get a similar coil. ? Until then the Equinox and the 10x5 will do fine for me!

....I'll put it this way .... during surface or shallow separation in iron "2D" similar to the Monte performance nailboard test ... the smaller coil always wins ... on any detector you use ....

..the smaller coil here always gives better results than more .....

And in practical detection it will also be confirmed ..... smaller coil can separate shallow targets much better in iron shallow..like a large coil..and you will see targets which, for example, the 11 "coil already has a problem detecting ..

Furthermore ... the coil could also detect a deeper coin .. especially if there is less iron on only one side .. from the coin at a certain distance ..
..but here a lot depends on the 3D separation capabilities of the detector .... and the separation well detectors prove the data signal on the deep coin even though it is really close ....

 

However, there are several situations in iron-polluted terrain where only a larger coil ... size 9-11 "can handle the detection of a deeper target.
which, when the detector is set correctly, will allow you to separate really deep targets between the irone ....

...here you can be a 9 "coil optimal in the separation ....

 

...... come to another important feature in iron separation .... and that is ... is the ID of the unmasked target....

So that's 6 silver targets found with your 10x5. Had you been using your 11" stock coil instead, how many of those 6 targets do you think you would have found?

I went over the spot where I found the small ring with the 11" not too long ago, got nothing but aluminum and iron. It wasn't until I came back with the 10x5 that I got the ring, a 1965 dime, and a 1912 wheat. ? The only setting difference was a lower recovery speed. Maybe that helped. I'm still trying to find a much more valuable ring someone lost there.

I find that it is much easier to hone in on anything with the 10x5 overall for sure.

I don't put much stock in contrived tests. I don't mean that negatively or to disparage anyone. The smaller elliptical just feels more accurate. Just my opinion. ? I know there are many other factors!

 ...The problem with the coils of Equinox is that it does not have a 9 "coil ..... and an 11" coil can be a bit big in some cases.

and another good thing is to optimize the recovery speed below the coil size and also the sweeping speed ....
