Was there only one size coil made or are there different sizes for the older units.

Don't think anyone else wanted to touch that one.

Didn't quite understand it.

I can't recall another Coaxial that was popular, and that one was for the much lower frequency VLF detector of about 34 years ago.
A coaxial coil is a bit 'different' from what we usually use and often they were quite frequently misdescribed. For example, if you look back at that old Garrett literature they stated the search coil only responded from the bottom and not from the top. That was an error because those coils DID respond from the top, but they responded in reverse. I know of a case where a fellow crawled under an old porch to look for dropped coins. It was a tight fit and he had to belly crawl and under a portion of this porch he couldn't get a good signal on coins or other metal targets below the search coil because directly above was an old iron stove on the porch.
Afterward he learned about the reality of the coil. I suggested to tune for a proper threshold and then increase it a bit. Use something like a license plate and wave it UNDER the coil and you got a positive 'beep', but wave it OVER the search coil and you would hear the audio drop off and null out. That, plus the fact that they were sort of ugly, thick, and heavy didn't help.
Anyway, I did use an old original Garrett VLF and it handled nasty ground well at the VERY low frequency, but I preferred the latter DeepSeeker offerings, and especially the 15 kHz GroundHog series, as they had coils that worked better.

I have the MH ADS 4 and at one time I thought I saw a co-axial coil that would fit this machine...I have been using the Eliminator Coil until my White's was stolen.
