Andy Sabisch is a better detectorist than I, for sure. I've only been at this for about 6 years. But I have found a buttload of gold rings, with Garrett, Whites, Fisher, and Minelab machines. And I will state for the record that IN MY OPINION, there is no machine that can tell a gold ring from a pull tab with any certainty. And I believe that many will back me up on this. The fact is, if you want the GOLD you have to dig the ALUMINUM...plain and simple.
That said, as somebody who has found many gold rings, I can tell you that there were many times I THOUGHT I had something good based on the sound and it turned out to be a pull tab. But MANY of the times that I found a gold ring I KNEW I had something good (and gold) based on the sound and distinct tonal quality. Which I believe is what Andy is talking about. It's not something that can be easily described, other than to say it's a "quality thing". There will be pull tabs that read 15 to 20 and there will be gold rings that read in the same exact range...forget the meter readings for gold. But when you hear REAL gold and that "round sound" (don't ask, can't do it) your eyebrows go up slightly and you have a keeper. It's all about swing time and knowing the machine. I use an Explorer II now but I found a few gold rings with my Quattro when I had it and I think the ferrous tones are best for me. When I'm detecting the beach with my Excalibur or my Explorer and I hear a gold tone I feel like I have a pretty good degree of confidence in knowing when I need to try extra hard to get that target before a wave takes it. I can still get fooled though, like anybody with any machine.
When I hunt with my Fisher CZ-70 it has the ability and depth to hunt the beach with the best of them but it only has 2 of it's 4 possible tones that are likely to be a gold ring. One is the tone for "Relic" and one is the tone for "Nickel". The tone for Hi-coin and Iron are not likely to be a gold ring, though possible. But all the aluminum and all the gold is going to be one or another tone on that machine and that's what you get. No possible way to tell a gold ring from a pull tab on that machine...dig and hope. So what you get with the Minelabs, aside from superior ground filtering and depth from 17 or 28 frequency technology, is a significant amount more information and criteria by which to make your decision "To DIG or NOT to dig..." which of course IS the question.

It takes time to learn to harness that information. Some give up and go back to the simpler machines. Others hang in there and the "light bulb comes on" one day and that's all she wrote. Minelab builds a lot into their machines and it's up to us how much we use and how we use it. If you run the Quattro over a pull tab it WILL find it. If you run it over a gold ring, it WILL find it. I'm definitely NOT one who proposes digging everything...not in my land hunting anyway. But at the beach that is the best policy if you want gold. And it's the best policy for a new user until they learn the nuances of the Quattro or any machine. Hope that helps some...probably not what you were looking for though.
