The difference in performance, or lack of performance, is only in the circuitry design and not the search coil size or type.
Thus I agree with the first part of your statement, but disagree with the latter part being that it is a Double-D design.

Sorry, Monte, I must disagree with that all encompassing statement. I was talking about target separation performance.

Specifically I'm talking about the parallel nail test with a target in between. I have yet to see a DD coil pass that test in the vertical (N-S) direction on any detector! To prove it has nothing to do with electronics, I can demonstrate this with the Nokta Impact. Using the 7" concentric coil, it passes easily. With the 5" DD coil, it cannot! The 5" is smaller - one would expect better physical separation of targets, but it is not the case. And as I theorized it is the broader shape of the DD field, front to back, encompassing more iron than the CC coil, masking the coin. BTW, the lowly old MXT Pro with 5.3" Eclipse (concentric) does a decent job on that test as well.

I used an Indian Head penny, which is a slightly more severe test than the nickel. The half-dime, I'm sure is tougher (I'm getting one Monday).

So I stick by my statement that the coil design has everything to do with performance of a detector re: target separation. You've preached for years, the merits of smaller coils for better separation. I say the coil design is also a consideration.

This month's Western and Eastern Treasures has a review of the Anfibio Multi. (10 pages long, BTW!) The author states (about the 7" concentric) "There are several top hunters who have stated that this coil will pick out targets in iron that no other detector they've used can see". I've seen others make similar comments.

One other piece of data, the AT Gold with 5" concentric passes this nail test. Of course, like all other detectors, with its larger DD, it does not.

Let's take a quick look at a test sample on the extreme opposite of some Iron Nail tests and use my 'short-stack' of US Silver coins. 5 Walking Liberty Halves on top of a Silver Dollar. And let's just use a 5" DD size on a top-dollar Fisher F75 and Teknetics T2, and a similar size and shape 5" DD on the lower-priced Fisher F44 or Teknetics Omega 8000 like I enjoyed Coin Hunting with. Which of thee four models from the same manufacturer, FTP, will produce a really solid audio response and a decent visual TID display on the stack of Silver Coins? The F44 and Omega 8000. What's the main factor providing the difference in performance? The circuitry design, and not the size, shape and type of coil.

As to this test, the results would be detector design dependent. I doubt the coil design has anything to do with this - assuming you haven't overloaded the detector.

Thanks For All The Great Info!

"Flagship?" ... How about 'Most Satisfying?'
