How can I tell the difference?????

[gbortnick]

Went out today and got really confused with the 250. Everytime I go out I can get a handful of coins with the Ace. Today I went to a fair grounds with the stock coil on and the sensativity turned way down. there were a lot of cans and bottle caps. I was getting a lot of silver readings and all I found was 3 pennys and a lot of cans. Why can't I tell the difference between coins and large pop cans. I really got skunked today and I can't figure out why?
Got any Ideas?

Because what happened to you is normal. The ACE 250 can't distinguish the size of a target, so it gives you a reading of what it "thinks" it is seeing. Most detectors see a pop can a coin type object. Your job (through experience) is to learn how to distinguish a pop can from a coin. How?........by raising the coil another 12 inches above above the target too see what the audio sounds like. A coin will probably not give an audio signal anymore, whereas a pop can or similar sized object will. And all machines will at times read a coin as a silver one. The ground conditions, oxidation on the coin, mineralization in the matrix around the coin make it difficult for any machine to be 100% accurate. The machine is only giving you a probability. Your job is to learn how to increase that probability, to the point where you can tell the machine what's under the coil, not the other way around. Then you can say you have "mastered" that machine.

Enjoy the thrill of "not" knowing what's underneath the coil, and the anticipation of what comes up. Sure, you will dig a lot of junk (like everyone else) but that's how the surprises come.

To add to what John described - try detuning. You can detune the signal pattern from a coin down to virtually the size of the coin. The same applies to a can which will wind up with a bigger signal pattern. Also use a probe with a round tip so you don't scratch an old coin. If you hit a can you can tell because it is soft and gives and if you push hard enough you can punch a hole in it - whereas a coin will be solid. What mode do you hunt in?

I do not use the ACE, but I would think it is the same as other garrets. Correct me if I am wrong.


In pinpont mode, you can tell size differences. You will notice a much smaller target size with a coin than you will with a can.

I recommend digging what seems like a can anyway. Many times I have dug silver items like spoons that seem more like cans than coins.

I dug this circa 1850 spoon in an area that was hunted and even had an archeological dig in the 1970's. Had I not dug, I wouldn't be posting a picture.

I agree with that,
there ain't no coin 6inch long on pinpoint.
It's more likely to be a piece of wire or a coke tin.
Uncle Willy is always telling the newbies to try raisin' the coil 6inches to a foot and if it's still strong it's a coke tin.
Mind you I can still get caught from time to time, but that's the fun part.

Yeah when in doubt - dig.

Don't we all bud. That's why it's fun, the mystery of it all. I don't dig up as many cans as I used to but I should. I dug up a flattened out beer can years ago that was full of probe holes, but nobody had bothered to dig it up and find the roll of quarters buried under it. I think about that every time I leave a buried can behind.

I would rather dig 50 soda cans than miss one silver quarter. Therefore I dig any and everything that sounds like a coin; after all, it takes only a minute or two to dig up a can.

If you watch the depth meter,when you go over a can it will jump from like 2 inches to 6 inches will quick.Unless it is a can that is stomp flat.But most of the time a big jump in depth means it is probably not a coin.Hope this helps.

Hey thanks for the tip ohio fred,

I don't think you found that with your MDer.

I am holding back from my "probe" comment.
