Hello again
It occurred to me the other night as I was going through Andy

Warriorwon, I really like your posts and ideas!!! The other thing that you mentioned hit the nail on the head, It takes time to learn the tones any detector has. I had an old, old, Whites analog detector a long time ago and if I remember correctly, it only had one tone on it. You ran the threshold and any slight change could be a target. Well, I could tell if it was a nail, bottle cap, or silver dime just by the slight changes to the sound. I spent a lot of time learning that detector and found many great finds with it! So time spent learning the tones will pay off later. Anyway, I will update ideas as I figure them out. Good hunting to all!!!

Yes, I wholehearted agree! The sounds I listen to are very important. I was at the beach a week or so ago, and it was getting pretty dark. My husband (Garry) who owns an Explorer 11 and I (using my Quattro), well, he had a back light to help him. I don't have one. It's 10:00pm and I'm relying solely on sounds because I can't see for peanuts. And I'm pulling out coins, and by the sound, I have a good idea what the coin is, then I feel the coin in my fingers, rubbing the sand off it. You are definitely at an advantage if you learn to read what your detector is telling you. And it often, it is a matter of whether to dig or not to dig. You explained it all very well warriorwon!
Cheers Angela

I am glad you noticed it. This method can help with to dig or not to dig. As I read, you have used the cross-saving. That is where this really helps. These are some of the things to remember:

Short Explanation:
Conductive Tone (coins,coin & jewelry): Reads 0 Lowest Tone, 40 Highest Tone(low 0 to high 40)

Ferrous Tone (relic, all metal) Reads -10 Lowest Tone , 40 Highest Tone(low -10 to high 40)


OK, Now with that out of the way. This is how it can be used in the field.

Here are some targets to think about(numbers vary a little):We will work with it as 3 tones even though it is a building tone. High, Mid, Low.

Quarter: 38 Con. High Fer. High
Rusted Nail: -10 Con. High Fer. Low
Nickel: 14 Con. Low Fer. Mid
Dime: 37 Con. High Fer. High

Try 2 targets silver dime, & clad dime. Before the test, answer this question. Do you think you can tell the difference? Then let us know your results.

So, easy to remember High High Dig, High Low let it go.

I think that you will be able to tell the difference in the clad 10c and the silver 10c. I think that the silver will give a higher tone in both the Con and Fer audio responses.
I didn't get a chance to get out today,better half kept me busy all day! Tomorrow I will run the test. I'm going from memory from my sound garden but I think that was the response I remember. My test garden hasn't been in the ground very long so I hope its not altering the response any.I tried to pack them in as best I could but there is no substitute for time no matter how hard you try.

I'll get back to you later.

Final answer:

Testing a 2004 10c and a 1947 Roosevelt 90% silver 10c from my garden.

In the conductive audio there is no difference in the tones between the two coins.

Because I knew before hand what was under the coil I think that there was a discernable brief BOUNCE when the coil went over the 10c silver. In the field this might not be noticeable. Once the coil honed in on the coins the tones were the same.

However in the Ferrous the tone change was defiantly discernable. The 10c clad gave a lower tone than did the 1947 silver 10c, which gave the higher tone.

Very useful in the field I only wonder now how many other discernable target can be separated by the use of the Conductive/ Ferrous audio cross saving?

Anyone want to give me some more comparisons?
