One old school way to determine square inches is to make a grid on paper of one-inch squares, lay the coil on top of it, draw an outline of the coil and count the squares inside the circle.

I'm going to try the Equinox without a cover and see how it goes. It might be all in my mind but it seems to feel lighter now when I swing it.
I've been using my 8" CZ20 without a cover in the rocks at the beach for a couple of months and I don't see that it's hurting it.

When you measure the actual centerline of the coils, the Ultimate 13" is only 11.5" and the 15" x 12" SEF is 13". Having the outer ring extend beyond that centerline may aid the performance in some way but to me, the centerline is the true useable length of the coil.
Personally, I don't like coils that are wider than the centerline length. That might be why the U

So the length of the coil has stayed the same. Unless the internal windings have been improved in some way, I wouldn't expect it to go any deeper than the original. Increasing the width of a coil usually doesn't affect depth much, but this is not your usual detector. It will be interesting to see the test results.

Definitely looks better. It appears to be the same length as the original coil.
Is there a reason why the rod attachment can't be in the center of the coil where it logically should be?

I never checked the actual weights. I can positively say that the 15" x 12" SEF feels a lot lighter than the similar-sized NELs. I've used them si

What are you putting it on? I got the Ultimate 13" for my T2 SE and it was no better than the stock 11".
If you want depth wouldn't a 15" make more sense?
I know the NEL's are popular but their bigger coils are heavy. I bought the Attack and Thunder for my F-75 LTD and did not like the extra weight. I very much prefer the SEF 12" x 15" for its lightness,

For wet salt/sand hunting, I'll bet they could make a CZ that could equal the Equinox. The technology is there. They just aren't using it.

Apparently, the Booster coils are only for the Golden Mask detectors. It doesn't say anything about what Booster means.
Here is the page on the NEL website.

I've been following the development of this detector from the very beginning and so far, I have seen little or no proof that the discrimination abilities have any advantage over VLF machines.

I use mostly tones on deep targets as well because the depth of the T2 can easily exceed the ability of the detector to numerically ID a target on the screen.
Deep non-ferrous targets will often be mixed with low tones. This can be frustrating because iron targets are often mixed with high tones. With practice, it is possible to identify extremely deep non-ferrous targets by tone most of the t

The 12" x 15" SEF is the coil that I use 90% of the time on my T2 SE. It gets fantastic depth and is a pleasure to swing for its size.
I bought the NEL 15" x 15" Attack and 14.5" x 10'5 Thunder for my F-75 and I don't like them at all. Compared to the SEF, they feel heavy and unbalanced.
The stock coil on the T2's have very poor performance IMO. Switc

I've had good results using the 5" T2 coil at my iron infested sites. If you want something not quite so small, try the 8" x 6" SEF.
For depth and coverage, the 12" x 15" SEF is awesome. It gets a good two inches more depth on a silver dime in my soil compared to the stock 11". Lightweight for its size and easy to swing. I can't say enough good things ab

It depends on the soil conditions in your area. Where I am, in Northern New England, the coins generally stop sinking when they reach the base soil layer about 8 to 12 inches deep. The base layer is usually made up of packed gravel or clay and doesn't move much. Any coins found within the base layer usually get there by means other than sinking, such as animals/humans digging, tree trunks fa

It changes on me every once in a while. Then goes back to normal after a few days. The subject has been brought up on the forum many times. Don't worry, the crisis is only temporary.

Those numbers are only possible in loose topsoil. At most colonial New England sites, the topsoil is usually no deeper than 15 inches. Below that is a dense layer of clay where targets generally stop sinking.
We do occasionally find deeper targets in the clay layer. They arrive at those depths over the centuries for many reasons. Animals digging, humans digging, tree roots being uplifted, eros
