How deep

Uncle Willy said:
That is a loaded question as there are just to many variables regarding depth of any machine and there is no set depth for any machine everywhere. Detectors do not have a universal depth for everywhere in the world. Depth is a fleeting term for bragging sessions and ad hype and means little in the scheme of things.

There is also this wide spread mystique that all old coins are buried halfway to China. They aren't. I have found coins from the 1700's at two inches and clad at eight inches in the same area. Just look for a good quality detector, learn how to use it, and forget about all the depth hype. Doesn't make any difference how deep it is if you can't find it.

Exactly right. :thumbsup:

Ok I'll say it once, for someone new, but that's it, no more not from me. If you wanna know the truth about MDing, no matter what detector you use. If you wanna go deep you have to search in all metal and dig it all. read up about masking for a start. Then also for those who don't know this little tidbit, no detector no matter how much you do or don't spend, is accurate at target ID beyond 4 inches. Therefore allot of older coppers and good finds etc... read as Iron beyond that. Although your detector might get lucky and guess right from time to time for the most part you gotta dig it all to be sure.  8)

That's a spot on statement if I ever heard one.

A metal detector uses phase shift to discriminant out targets.

The deeper the target the weaker the phase shift it will produce and that causes a good target to be discriminated out.

Throw in some fancy software to read the phase shift and you get target ID.

So to go deep you must hunt in all metal and dig it all.

Check out My test I did last week on 3 metal detectors. It really opened my eyes to a few things and it has caused me to start hunting using different methods.

Yep, maybe no one told you but your search area gets smaller the deeper you go. If the deepest your current detector can reach is say 6 inches. Then at six inches the search area may be only about 2 inches wide. so over lapping your swings by as little as a couple of inches will net you more finds and less stuff passed over. :wink:

Unless you are using a DD coil :wink: :wink:
 

That's true I understand the DD coils expand the deepest search area to almost double, so that would be 2inches x 2 = 4 inches. So now you only have to overlap your swing by 4 inches instead of two. :thumbsup:

I just read that,very interesting indeed.So, I figured I would do my own test too on my BH ....
Buried all 4 of the US coins...on dry dirt(no rain for awhile) it read exactly what each was up to 3-5 inches,any deeper it would get crazy beeps and sometimes no beeps at all. Its just not acurate at all.So for me, Ill keep it in deep mode and just keep digging everything like I have been doing until I get my up graded one.
 

What would one use this one for?.......Fisher Gemini-3 Metal Detector
I suppose this isnt good for just going out and looking for rings or clad? Does it pick up one coin, or is this one for the "vets"?
 

It is a 2 box detector mostly used for bigger targets at depth (i.e. pipes) and/or caches at depth..
Pretty much anything big and deep. Won't hit on single coins or rings I think.

Well, the ground has been kind of damp ,so I go to my front yard 'again'......
I went over the usal spots, get a iron sound.Dug andfound a 1967quarter,1969 nickle and a 1970 penny.Basically in the same hole.(within inches of one another) I didnt get a coin beep.So the more I use it the more Im learning it.It might just be getting wore out too.It has some miles on it now...lol
I know dang well I'v been over that same spot befor.They were about 2-3 inches down.

Keep an eye on and be sure to check out that 1970 penny. It would be grrrrrate if it was the $35,000 model ! Which iirc is the "S" mint mark.
 

Here in Utah I dug a medium sized pancake lock at about 15 inches in moist soil. I was using a DFX with the super 12.
 

Soil type, density and moisture conditions play a huge role in depth. I've dug to date a half dime at 10-12 inches deep which gave a descent signal with the whites DFX with the standard coil. Again I think its all relative to soil conditions and users familiarity with his equipment than the equipment itself. I've hunted alongside of Minelabs, Tesoro, Fisher and picked up on signals either they missed or overlooked and I'm sure they have done the same to me. Good luck! Use what you got to get what you want!
