I fully believe that this machine, AT Pro, is going to be the finest gold jewelry machine that I have ever owned. I'll tell you why: I borrowed all my wifes gold rings, and other rings and chains that I have found over the years, took them to the back yard and did some tests.
I used the pro-zero mode, sensativity at 3 notches from the bottom, with iron discrimination at 35.
All the mens gold wedding bands(14kt.) fell in the range of tid 63-67, depending on size. The womens gold rings that were small to medium regardless of kt. weight fell in the 43-48 range, one larger ladies ring came in at a solid 52(same as nickels). Gold chains would almost always come in at 41-43,regardles of their orientation to the coil. Though several would have a broken tone.
The one thing that I found fascinating was the fact the rings or chains would 'lock' on a number and would not vary more than two numbers , and most times not more than one number period. Several rings would lock on and not vary even one number. I then compared that to various pieces of foil and aluminum that would also fall into those number ranges, and the numbers on those targets would 'bounce' 3,4, or 5 numbers . Now this is what my old DFX would do in 15khz, and I found plenty of gold jewelry with it.
Took these facts to the park today, and though there was no gold today, I dug a lot of targets with these varying numbers, and every one was indeed trash.
My conclusion(though not professional I'll admit) If targets fall into those ranges and have an excellent tone with the numbers holding solid, DIG.
Targets in those ranges with bouncing numbers varying by 3 or more numbers will almost always be trash.
Anybody with anymore input on this gold subject would be greatly appreciated.
Thanks

It's always nice to know about little tips that get discovered that aren't in the manual. That's why it is so important to dig all targets when first using a particular metal detector.
