Deep on...Deep off.......did testing in my coin garden

[Goes4ever]

ok I just did my test I told you I was going to do. My ground is pretty moist, not sloppy wet, but very moist. I used a modified coin program, auto +3 sensitivity. I did not swing over target again and again then write down a number. I swung left over target and recorded the numbers, then back right over the target and recorded the number. so it was left, right, left, right. I tested it over 3 different coins, all buried at a MEASURED 7.5 inches. Coins were all placed on large plastic plates 2.5 yrs ago to keep coins flat and also to keep them from sinking.

I tested a clad quarter, a silver dime and a 1940's wheat. Here is what I got:

deep off, fast on:
quarter 11-46, 11-46, 12-46, 10-47
silver dime 13-44, 17-43, 14-46, 15-45
wheat 09-44, 13-43, 10-43, 12-43

deep on, fast off
quarter 05-45, 10-46, 11-46, 09-46
silver dime 06-49, 16-48, 11-45, 10-43
wheat 12-45, 13-45, 10-43, 16-41

both deep on AND fast on
quarter 11-47, 05-46, 03-46, 11-47
silver dime 04-45, 12-40, 01-42, 08-46
wheat 13-44, 10-43, 11-44, 12-45

now this is far from scientific testing...lol, but it looks to me like deep off and fast on produced the most stable readings. and having both fast on and deep on proced the worse readings, especially on the silver dime. I thought it was odd the wheat was reading so high, but have noticed when the ground is saturated, wheats register a bit higher.

So there ya go, take it for what its worth, I will continue to use deep OFF and fast ON

Thanks G4E. I came up with the same conclusion. Good to have a confirmation.

My tests results are very similar and I always hunt with fast on and deep off.I think for larger deep relic hunting the deep on might be better....

Did a little testing myself and got pretty much the same results, but! What I also noticed was less depth. So essentially you're getting less depth which means the target has to be closer to the coil which also means a more reliable target ID. All my deeper targets were hardly audible.

Did you notice any differences in the audio response with the 3 different settings that you used?

I have found that the "deep" setting by itself allows for what would best be described as "hints of a high tone" that you do not hear with fast on by itself or with both deep & fast on. Usually these hits turn out to be deep (8"+) wheats or silver. Stable VDI on deep targets is usually wishful thinking but often times these partial high tones are combined with flashes of high VDI numbers (12/45, for example). Just wondering if that has been your experience as well.

I did not notice any difference in tones at all, all produces tones that I would have dug, regardless of the numbers

Good test
Thanks for the time well spent
