The Nokta FOES CoRe and FORS Relic are still my #1 detector choices for the really tough, iron contaminated places I like to hunt.

Will an AT Pro or AT MAX or White's MXT Pro or MX Sport or MXT or Minelab Equinox or probably Vanquish find good targets in those 'test Site' towns? Sure they can, but none of them would be my primary detector choice. I know the CoRe and Relic can do well if taken for a hunt in a typical urban Coin & Jewelry Hunting locations, and I have done that in the past, but I also feel some other models just might make a better choice, and there an Equinox might have an 'edge'.

I get a kick out of how many people spout the wonders of the magic 'Multi IQ' and 'Simultaneous Frequency' performance, so I suggested a simple 'Test' on Friendly MD Forum. Similar to my Silver Coin Stack, I asked EQ users, or others, to stack 2-Silver Halves on top of 2-Silver Dollars, all bare and touching. Then test it with Multi IQ to witness the 'magic'.

Here's a link to Jeff's response: [metaldetectingforum.com]

And here's a cut-and-paste of his results:

'jmaclen': I used an Equinox 600, 11" DD coil in Park 1 with all target ID segments accepted -9 to +40 with GB at 4, sensitivity at 15 of 25, 5 tones, recovery speed 3, iron bias 1, multi frequency.

Used a 1892 and a 1921 silver dollar and a 1940 and a 1942 silver half dollar.

Two silver dollars stacked: numerical target ID +39 to +40 with high tones
Two silver half dollars stacked: numerical target ID +39 to +40 with high tones
Two half dollars stacked on two silver dollars: numerical target ID -9 to -6 iron grunt low tones with the center of the DD coil directly over the coins....... +30 to +40 at the edges of the DD coil

I broke your rules and stacked the silver dollars on the half dollars: numerical target ID +39 to +40 with high tones.

Used your original scenario with the same settings except single frequencies

5kHz Two silver dollars or half dollars separately: numerical target ID +39 to +40 with high tones
5kHz Two half dollars stacked on two silver dollars: numerical target ID +39 to +40 high tones

10kHz Two silver dollars or two half dollars separately: numerical target ID +39 to +40 high tones
10kHz Two half dollars stacked on two silver dollars: numerical target ID all over the place along with multiple tones.

15kHz Two silver dollars or two half dollars separately: numerical target ID +26 to +40
15kHz Two half dollars stacked on two silver dollars: numerical target ID -9 to -6 directly over the coins with iron grunt low tones, +20 to +40 at the edge of the DD coil with medium to high tones.

Just for fun I tried my loaner a Teknetics Minuteman 7.8kHz with 8" concentric coil. Aside from overloading it had no problem with any scenario and correctly detected with 95 to 99 numerical target IDs and high tones with no iron grunts (I had iron volume on).

So, along with the limitations of DD coils for this test, did I just experience silver wrap around with the Equinox?
thanks,
Jeff

I knew what to expect the results to be, but thought a little eye-opener might be fun. All the EQ users out there but with Jeff's reply, all of a sudden that topic andreplies came to a halt. Just kind of a fun experience to try different things.

I'm sure the EQ series can do fairly well, but I would expect the 6" DD to be the better coil to mount for an edge in performance results.
