Going out to my House on the lake later on today.
I think I am going to start making a test garden but first I have to get all the things I need.
any suggestions about nails and where I can get everything I need.
unless you dig it silver coins are getting harder to come up with.

I have a junk container for metal detecting and that’s where I get my “junk” for the test garden , you know , foil, nails , pop tops, just whatever you find in your spots
I had a bunch of silver to be cashed in so just buried coins from that pile.
Rings and jewelry , I would put in a plastic bag if you want to test it, I just air test for that kinda stuff .
Pawn shops are a good place to find stuff if you can buy it right.
Let us know how ya do

All you need is a few clad dimes at different depths, lets say one at 5", one at 7" and maybe one at 9" or 10". Then your garden needs set and season for several years before the coins start to act like lost coins.

If you can get your detector to hit on dimes, there is no need to plant larger coins it will hit them.

I kind of feel that a test garden is a waste of time and you will do better with lots real world hunting.

Good luck,

I won’t to do one too. Just to play with. Probably just use clad for mine. I watched a guy make one and dug the holes then side bored sideways slots for his targets. That way they were under Undisturbed ground. I’m always taking someone new it seems and it would be a good training tool. To hot where I am right now to work on it. Good luck!

If I were to plant another test garden I believe I would try this, I would dig the hole to the depth I wanted and then reach in and force
the coin into the side near the bottom of the hole, maybe make a little tool to push it in with, then fill the hole back in. The idea (still to be proven)
is this leave the ground above the coin (test target) undisturbed.
Both my brother and I have had garden planted coins beyond 6" to test (detect) when first planted and then become undetectable a few days later.

Good Luck

ok I had one before but I went in on an angle fr each depth.
I dug some junk today with the max-that is a small start

I also used the system to wedge the coin in the sidewall on several coins, which also disappeared from detection. My guess is that those wedged coins eventually slipped to an angle into the looser fill dirt. I have a half dollar at 10 inches I can't detect after more than a year, going to 2 years, after burying. Maybe we need to pound the immediate dirt near the side walled inserted coin more sternly.

Coin dealers have junkers that are great for burying. They don’t cost much. Test gardens are great training grounds for new and old settings. Sometimes I get a great idea and go out and test it .It gives you a base to start from. Be patient as it takes a couple of years to settle in

I'm putting in a test garden for a specific reason and that is to test my detectors, and me, on what the sound of deep silver sounds like. I have an AT Pro, an Infinium LS, and an AT Max. Between the three, which I've used in the water, on farm land, and at old house and farm sites, I've dug about 5 silver coins over the last 8 years. I'm convinced that I've missed some. So, my goal is to become an expert on my ability to know when I'm over silver with each of my machines. That's why I'm putting in a test garden.

For planting the garden, I'm removing small sod plugs in my back yard, drilling a 1-1/4" hole with a drill bit to depths of 6" - 12" deep, dropping in the silver targets, tamping the dirt back in, and replacing the sod plugs. I'm not removing all the metal in the test garden area first; I want to know what silver sounds like among whatever is there. The only thing I'm undecided about is how to map out the garden. I'm getting up there in years and if I don't have a good map, I'll forget where they are. I've been thinking of stretching a line between two permanent points and hanging tags of some sort on the line with notes as to the locations and types of silver.

Thanks for the read. I'm looking forward to your comments and suggestions.

Okay, people seem to sometimes take my post in the wrong way, so let me say this first! I'm trying to help in the best way I can even if the wording comes out wrong or is taking wrong :smile:

The sound at depth will only change if the detector has modulated audio (if I remember correctly) that is when an object sounds farther away (fades) as distance is increased between the target
and the coil. Well in that case its distance and not so much what is making up that distance, water, air, or dirt is all distance! In other words you can do air test and get a good idea of the sound of
modulated audio response, the target response should fade as the distance is increased.

Now there is MANY things in the ground that changes the detector's response to good targets, and its possible to recreate some of them while its impossible to recreate all of them.
A coin tilted enough will often time give a double beep beep and do so to a point that it will have you digging two holes to find out that the target is right smack in the middle of both digs.

Next is target masking, but the problem here is every masking item is a little different based on size, alloy, above or below the target, how close it is to the good target. There is just two
many variables to try and include in a test garden and I'm not saying the idea of a test garden is a bad thing, I just don't know that its that great of a thing for much of what your intending to try and do.

To get silver coins the coins has to be there first. In many areas where metal detecting has been VERY popular for more than three or four decades the silver coins have been thinned out a LOT.
Next I look for things when I dig that hint to the age of the area and items lost, like wheat pennies, or at lest pennies dated pre 1958. I look for the old beaver tail beverage tabs. If your digging those then
your doing the right thing to find silver, especially wheat cents.

Here is another idea that may help you find some silver coins, when you first start a hunt and your still fresh dig a few more of those questionable targets and try to make a metal note of how it sounded
and what came out of the ground, now I get tired of digging so many extra items to do for the entire hunt, but I can deal with it for awhile, this is one key element to gain experience and a bond between
the operator and his/hers detector.

There is a couple of fair grounds around our area and they are several people that hunt them as soon as the tent stakes are pulled up, well it took me awhile to learn this but I started tuning in to those broken
responses, but ones that sounded more like bunches of close together good beeps and when I did that I started finding pocket spills!!!! then I started finding pockets spills that were 3" and 4" deep that had
been past over for several years. To to many detectorist a broken response from a pocket spill sounds closely the same as a junk target.

Another thing I've found over the years is a repeatable beep to many means totally different things. I've learned that often times a repeatable response in ANY single one direction is the DIG target,
it doesn't have to be a back and forth in the same direction, or a four way pass, if I can get a repeatable response in any even single swing in any direction I'll dig, so many times it'll be a coin.

You can gain the most experience by digging more questionable responses in the field, and making mental notes to what came out of the ground by what it sounded like. I've read post on forums
where the person only digs 4-Way repeatable responses! I love to go behind these people and hunt, they only get the easiest to get targets and leave so many good targets, then you have people that only dig
the 2-Way responses, they are still people I like to go behind and hunt because they still leave a lot of good finds. Don't get me wrong, I'd rather get there first but that just don't happen much these days, somebody
has hunted it before. I learned the single response method while I had my CoinStrike, I was hunting in a heavily hunting park and I was getting a lot of responses that I could only get in one single direction, the
area was old enough that I knew dated back to silver, so I started digging some of them and I was amazed at what I found out, a good bit of them were coins that were in close proximity to a single piece of trash
metal, swing in one direction (will say south) and the response dropped out, swing (north) and I a good response. And in most every case it was either a coin and junk, or at lest good piece of metal next to a piece junk.
Often times while hunting those fairgrounds I've found clad dimes and quarters mixed in with a Zinc penny pocket spill even though I had Zinc's discriminated out, because of a hint.

What I'm trying to convey is a detector in LOTS of cases will hint to a good target more than it LOCKS onto one, and to learn when its a hint and dig is when a person becomes more in tune with their equipment.

Now, back to your test garden. I would never again plant a test garden deeper than say 6" and the only purpose for that is a bit of an aid for getting use to a new detector. Once you past the 6" depth range in the field
they're is just to many variables that can change the target response that would be impossible to recreate in a test garden.

I planted mine in a pattern and mapped and measured it out on paper. I’ve got a clip board with the info I can take out with me if I need help remembering object Nd depth.
It works

I like all the test garden theories above. Waste of time, impossible to recreate, etc, etc...…… A test garden will be the best thing you have ever done for your metal detecting career. If your soil in your garden is remotely close as to what you hunt in the results will be very close. You can bury deep targets , masked targets , coins on edge and cut your learning in half on those type of signals.


Its funny I hunt some of the oldest sites in the country and here all that jazz about how a target has to be buried for a long time etc etc . I find that my detector acts pretty much the same on a 8 inch silver coin that's been buried for a year and one that's been buried for 200 years.


It is true there are varibles but these guys act like a detector acts TOTALLY different in a test garden than it does on a 200 year old site and its just not true. IF you want to know how your detector acts on the targets you desire and learn some of its nuances on such targets build a good test garden!!!!!

Well, these guys for SURE found out that in WV dirt coins planted less less than 6" for the most part are fine, beyond and they're fine for a few days! after that there is a good chance they will somewhat vanish.
I've got three 7" nickels that have been planted for now maybe three years and POOF! My only success planting a coin beyond 7" was a US large cent wrapped tightly in a baggie and planted at 8" I have no idea
why that one seemed to work. According to some information that I ran across several years ago that was put out by the White's company stating that planting coins disturbs the "Ground Matrix" to much to get REAL field results.
I had a silver half dollar planted a couple feet away from the Large Cent @ 7" It worked (detected) as good as the large cent did for three days and then POOF! after a fews weeks I just dug it back up and replanted a regular clad
half at 6".

I know results with test gardens will very from one location to another. Also I never said it was a test garden was a BAD thing, I've just found them more useful in getting the feel of a new detector, and because of problems that I've had with
deeply buried coins I just gave up on planted a coin beyond 6". I do suspect that I might????? be able to get a hit on the lost coins by using All-Metal, but I NEVER hunt in All-Metal!

Good Luck with your 12" deep test garden

Your all OVER THINKING all this.All these assumptions end with,"they may be different in your Case"...Which renders all this meaningless.
