Escape, the only thing that I might offer, IF the EQ in Multi-Tone (50) is like the Minelab Safari, then I found that on the Safari a standard size gold band, such as my own, will show a say 14-15, as well as a bottle cap, difference is in the tone, high pitch tone, most always, bottle cap. Mid tone to a upper mid tone, pull tabs, sinker, nickel, gold ring. Generally speaking. I would only guess that with 3 or 5 tones?, many would be lumped together. Someone with a better sense of hearing might separate even better. In a park setting there is of course many signals at times, and VDI #'s will bounce around and cannot always be counted on at all. As of yet, I have not bought a EQ, but will be, I believe it will outclass the Safari, I am only guessing that both being a Minelab, both having Multi-Tones, (like a flute), they may read the same.
