In my recent testing i was air testing in all metal at 7.5"on a gold ring and a quarter at 7.5" i could not hear the quarter but the gold ring was just punding thru in fact i could get it at 8" easy i could get the quarter at 6" with a diggable but soft sound , and it really goes to point out if you are looking for silver coins this is not the machine not to say it could not find them but a machine like the F-4 with a lower khz would do the job better and go deeper i also did a hot rock test badd hot rock stops every madhine in disq from seeing the dime under it yes even the gold bug , But hear is the good news i ground balanced over the rock and in all metal got the dime with a clear resounding signal and even better with a gold ring . this will be the machine for finding gold rings and it is a great machine i like the ability it has to I.D in all metal on the graph this machine has a great all metal mode and it loves gold ,

Gold Bug is a gold machine ,

Gunnar -- you have a problem with your machine. You should easily, easily hear that quarter at 7.5"...
I would send your machine in to Fisher...I think you ended up with one of the older machines that had an issue with deeper high conductors. There is a fix for that...a VERY GOOD fix. I can air test a quarter to 10-11" in disc mode, with mine (and 11" coil).
The machines, as you say, LOVE gold, but they do a great job on coins as well -- but you have one of the older ones, apparently, that needs to have the "fix" applied. Once fixed, it will surprise you on clad and silver coins...

In two and a half years with the bug Ive found enough gold to pay for it 4 times and Ive only found 6 silver coins. The bug and g2 have a bad wrap around problem on large silver. Hits small silver very hard and with good id. My G2 Reads a 100 ounce silver bar as iron and barely hits it. IIl have to do a video of this with 10 oz bars and see where it starts, see what you all think about it and if its wraparound effect.

Guess it depends on what you mean by "large silver," godigit...while I can believe very easily that the machine might have problem with 100 oz. bars of silver, I hit silver quarters at 8" to 10" in my test garden, no problem...
I just want to make things clear to new users -- some of the OLD GB Pro machines had a problem with silver coins (limited depth-of-detection), but later the software was "tweaked" or "fixed" to eliminate this issue. I hit high conductor/silver coins very well, at very respectable depth. Some folks insist that their GB will NOT hit coins well, and I think much of that is often due to it being an older version of the unit, as my results are very, very different.
Not trying to be argumentative, but just trying to be clear for everyone.
Gunnar --
Yes, the 5" coil will not be as deep; 6" on a quarter with a "diggable" but "soft" tone, and no report on the 7.5" quarter, might not be TOO far off, in disc. mode, with the 5" coil. Try the 5" coil on that 7.5" deep quarter in all-metals mode, and it should hit clearly. If so, then you are probably not far off, with the 5" coil. I haven't used my 5" coil much yet, so I'm not sure. I find the 11" coil to be plenty deep on coins...and all-metals mode is a good 2" deeper still...

steve no problem , i welcome advice, and truth I was not aware of that isue, and dont get me wrong i really like this machine , the fisher designers did a great job its going to find some gold for me , i just have not got out to hunt with it i have been hunting on the farm and its sparse hear today in the gravle road i found a pull tab 6" deep with a resounding clear signal thru the gravle , and then i found a 11" deep old zinc jar lid but when i get this baby out to the schools and parks it will bring home gold thats my favorite thing about this machine is how hard it hits on gold ,
Hey Steve!
I'm not trying to make any one mad Just stating what I know for fact with two software versions both a 2 (which never had a silver issue it was the 2.9SE) that had issues and a new g2 version 1.
I never said it doesn't hit silver coins My bug and g2 both test out very close to your stated deapths. I should have clarified, they hit large iron better than large silver. (Large is bigger than coins) I find allot of silver jewelry and not so many coins but I do not specifically go to target coins I target Jewelry and I find It.
Also I'm not bagging the bug or G2 I love mine.
This is indeed the purpose of a brand specific forum to compare notes and debate the good and bad of any machine in a constructive manner!
Be Well
Jim

Jim --
I'm not mad! Not at all...
If you got that from my tone, I apologize.
I absolutely agree that the purpose of a brand-specific forum is to debate the good and bad, constructively; that's all I was trying to do. I was just trying to offer a counter-point to anyone who is "on the fence" about buying a Gold Bug Pro or G2, and hoping to use it at times as a coin shooter, that it WILL hit deeper silver coins with no problem. There is sort of a "reputation" in some circles regarding the Gold Bug Pro/G2 that it does not hit coins very deep. I strongly disagree with that, and I just wanted to offer a counter-point in this thread that while some, older Bugs DID struggle, new ones will hit silver coins at very respectable depths.
In any case, I mis-understood, I think, what you were getting at. I thought you were saying the reason you have only found 6 silver coins might be related to them "struggling with large silver." When I hear "large silver," I think quarters and halves, and that's how I interpreted it. That's why I posted the 8" to 10" depth on a silver quarter thing. But apparently you weren't even talking about coins, so I simply mis-understood.
Anyway, it's all good -- didn't mean to come across as mad or confrontational at all, Jim. Sorry!

The gold bug will surprise you.I mainly use it to prospect and have been doing very well with it. But recently Ive used it in nailbeds with the 5 inch coil and pulled stuff out. Also been using it in the grass strips and pulled a barber dime from 5 inches. Gotta use the right tool for the job.
