Mr. Rich,
I know that copper / silver gave the same reading on the 180 meter. But when it came to low - mid tones the sov seemed to separate better. (at least it seemed that way to me) however you are right the more I think about your statement< "I think it is the audio of the Sovereign that really was the key. Do the little Sovereign wiggle over a quality target and listen to the audio lock on and start to climb. Take a peek at the Target ID and see where it tops out. Do the same wiggle over junk and the audio would give it away."
The audio on the sovereign series was simply the best to me. For example, with the same TID, pull tabs were more of a rough sounding target and gold seemed to be more mellow. At least this is the nuance that I learned with the sov. I agree, the equinox is a super fast machine and have made some wonderful discoveries with it. - Jim
earthlypotluck,
First question, what is it that you're hoping to separate out from the rest of the target ID scale?
Don't forget about the original 550 scale on the sovereign. I still have a couple 550 units somewhere with some old coils and the like. Typically, with a larger scale, the ID #'s bounce around all over the place, and there has to be some sort of averaging taken into account to give stability to the reading.

How useful is it to have a 550 scale or a 180 scale or a 100 scale, or a -95 to 0 to +95 scale? If you remember the sovereign, all the higher conductive coins were pretty bunched right at the top anyway, so how helpful is that? Tesoro had the same deal with the Toltec series, TID's all bunched at the top with a lot of mid-range separation to help sort through nickels and pull tabs and square tabs and other junk looking for gold rings.

In reality, I am finding the target ID scale of my 800 to be fine. Perhaps I've just become used to it over the last 15 months or so. It has its' own characteristics that are helpful as I hunt. Much faster than my old Explorer, Etrac, XS-2a Pro or GT.
