El Nino....... good post/video.
Chris....... yes..... multi-freq has superior advantages if engineered properly. These tests displayed exactly that. (Unit sounds like a Minelab)! Those two different coil configurations AND different coil sizes can really skew the data (and invalidate the test); yet, comparable coil size/configuration may not always be available........ and ........ you have to test...what you have!
"UNDER THE IRON CARPET"
Re: "UNDER THE IRON CARPET"
Mr. Dankowski-Tom ....you are right,,, work Concentric coil and *DD coil can work differently on the same iron objects...
I did a slightly different type of test where a detector is tested for discrimination of 12 different pieces of iron... and at the same time a test for unmasking a nickel coin under an "iron carpet"...
VERSA..23DD coil

In this test, Tesoro Mojave had a problem with the discrimination of flat iron.. 2 pieces of iron gave a non-iron signal... but when separating a nickel coin under an iron carpet, it was able to give a partial signal or rather a hint of a signal on the coin.. I note with a really slow sweep with the coil ..
VERSA.. on the "multi-frequency" surprised me a little during this test, because even at the zero setting of the filters../Iron filter/ and /bottlecap filter/ ..it gave a non-ferrous signal only on 1 piece of iron,,and on the other piece of iron it was 50% iron signal/50% non-iron signal from a total of 12 pieces of iron... and at the same time it unmasked the coin quite well under the iron carpet from three sides of the coil sweep..
I did these tests in the spring of this year...and I included a few more...detectors...in the tests.

From this test, you can see how effective you can be in detecting good targets vs. unsolicited targets in practical detection...

Re: "UNDER THE IRON CARPET"
Very good tests. Especially..... all of the individual DIFFERENT types of ferrous/iron targets......,,,,,,....... to include flat iron. Flat iron is a achilles-heal to ALL detectors. Very few detectors give you any tool(s) to adjust/compensate/alter responses to flat iron.
Sometimes..... Single Frequency units "appear" to do better with certain iron; yet, at the compromise of unmasking.
Sometimes..... Multi Frequency units can 'false' on certain iron targets at a higher rate; yet, with a little bit of practice/skillset..... the operator can (fairly) easily discern between the 'falses'....... and ferrous/non-ferrous (co-locate) scenarios..... for enhanced unmasking capabilities.
If you dig deep into Manticore's tools/featureset....... you can easily unmask at a higher plateau.........next-Generation technological advancement/capability.
