That’s a really good idea, especially if it became standard much like the Monte nail board test.  Looking at it, you wonder why no one has thought of it sooner.  So, hats off to Nexus for coming up with such an idea and also offering peeps a free PDF download.  Thanks for posting.

I like it.  An aluminum composition disk set would be a nice addition.  Not exactly inexpensive though.  I screenshot from this webpage.

It would be good if it had an X&Y scale printed on it so test coordinates could be documented.

As a good analogy for this test, it would be good to say.. "The dice are thrown".../Julius Gallius Caesar/...

How many 3D  targets do people actually dig?

 

Never really heard of the 3D stuff as it seems to be a relatively new problem.

I question the usefulness and accuracy of such testing unless maybe if you buried the whole assembly.

Once upon a time there were guys doing mostly depth tests using what appeared to be a straight up wash side with holes drilled horizontally into it that targets on the end of wood or plastic rods were inserted into, the holes being at different depths and the targets of various kinds and detected from the ground top. Similar ideas using containers filled with dirt also were used. NOW THAT is more real world, and could be also used for separation tests with appropriate holes.

Now that I’ve thought about it more and actually watched some videos of it being utilised.  I now question the usefulness of such testing myself.  If anything, the 3D design aspect could be made more simplistic making it easier for peeps wanting to carry out such tests by utilising more easily gathered universal materials should they feel the inclination.  For me, once you realise how little iron it actually takes to influence and change a signal, most especially coupled with the ground matrix and the angle of approach.  I think it’s better to just enjoy detecting and learn your machine fully and hope you’ll still find the goodies!

2D separation is a type of separation when the iron and the coin are in the same plane...a very good example is the Monte Performance Nailboard test...And yes, this test can be demanding on many detectors...
This test simulates well the conditions of a ghost town...and similar terrains where civilization has lived for, for example, 200 years,,, and terrains where coins and iron can sink deeper and remain shallow in the terrain...practically almost at the same depth level...

3D separation is a type of separation where coins and iron are stored at different depths....often it can be a depth difference between iron and a deeper stored coin, for example, even 10-20 or more centimeters...because these terrains also have civilizations more than 3000 years old....

For this type of separation, the given detector + coil..must have...the so-called 3D separation predisposition...so that the detector can really separate deep well a coin placed among iron placed higher...

there are detectors that handle 3D testing very well and also prove it in the field...
