AT Pro tones

[D&P-OR]

Does the zinc penny come in as "high tone" on the AT PRO?---According to Garretts chart, it looks like it does to me.----Or will the zincs & I.H.'s sound different in the Pro mode?----Will you be able to distinquish them (audio wise) from the coppers & silvers?

It looks to me that the zinc is medium tone. The high tone starts at #80. That is the dime/copper cent range. You can see the 1 cent icon is in the 70's. As far an an Indian sounding different than a zinc? I doubt it. But the numeric ID "might" give you a clue. Either way it should be dug especially if hunting an older site.

medium-tone audio in both the STanDard Audio function and PROportional Audio function, based upon the numeric break. Good Copper 1

No detector can discriminate that tightly because there are difference in the way some cents read versus a "standard" one. This is especially true of older copper cents because as the corroded and get that green stuff on them, their conductivity drops lower and lower. In fact I would say it was normal for most Indian Head Cents to read below zincs due to the corrosion factor. I dug a 1868 Indian Head Cent that came in at a 42 (using another brand of detector) which is the same reading that pull tabs generally come in at. In fact I had dug 5 or 6 pull tabs from that same field that all had come in at 41 to 43 or 44. When I came across this target I could hear it was different from the other targets and I just knew the second I heard it that I should dig it. That is the advantage of what Garrett is calling Pro audio.

A few weeks ago I came across a target that read a 65 to 67 (down in the zinc range) and it was a 1831 large cent. I have dug colonial coppers (mostly British) that have come in all over the TID scale too. The more discrimination you use, the more good targets as well as trash you leave behind for others.
