CTX Giving the wrong tone-please help!

[IDXMonster]

I ran over a bottle cap last night and was shocked that it sounded off with what is clearly the wrong tone. This video shows the play by play. WHY in the WORLD would it do this?? Do I have something wrong with my machine like corruption in the software? https://youtu.be/e7gv9lEiGF8

Nothing wrong with that bad boy your using ferrous coin will do this with nickels to , where you will get a 12.30 on a nickel but it well give you a high tone from your nickel bin. It's getting it's high tone going back and forth and when it hit's the nickel bin there's your high .

Now since your getting a high tone from all the other modes that caps conductive #s are 13 or 14 and should give you a high tone . Now in ferrous coin it's trying to separate the iron from the conductive metals in the cap I could not see your screen but I bet it was traveling from 12.13 to 12.23 and maybe higher , nickels do this to deep nickels where the iron in the soil and the nickel are as 1 target so they go from 12.13 to 12.30 or there about . So the ferrous coin mode is trying to separate the two that's why it's traveling back and forth on the screen it can't make up it's mine is it nickel or is it iron .

I hope you saved the cap and let someone else run over it but I think they well get the same results . As far as the cap they all are zinc coated copper coated or have aluminum foil in them to keep the fluid from rusting the cap that's why it's sounding off as the cap rust it becomes easier for the machine to tell the difference because the non-ferrous metals have leached away .Or as I say it's a bastard cap just one of those that dose it no different than a bastard nail . sube

Thanks Sube! It wasn't doing ANY traveling and was hitting every time in and out of the ground from 11-18 to 11-24. You can hear how solidly it was hitting! I am going to assume that like you say,it's a bastard cap comprised of a few different metals and it's an anomaly. I don't EVER dig up crown caps with either the CTX or Explorer2,never have. This one was a weird one,and NO..I didn't save it! I didn't want to carry it around and give me any bad luck....

yeah once in a while you will run across a cap like that it all depends on the metals it's made of nothing to get alarmed about

 

[IDXMonster]

Thanks Sarge,I was pretty puzzled there when that happened! At least IF it does it again,I will know what's going on and have a good idea of what it is before I don't dig it...

We get um on the beach......... some are adding copper to them. Like corrona and bud.

Thanks Dew! Good to see experienced guys saying that they've seen the same,that's a BIG relief! The machine has been SO good that I'd hate to question it. Without trust in the machine I have nothing...

I've run across a few like that.---Keep 'em for my tough testing scenarios.---Nasty little buggars they are!----------Del

"There is no such thing as 'the wrong tone!'. A detector looks at [ a piece of metal ] and does a few computations and puts out a sound that 'it' determines the conductivity of said piece.
There will always be that [ piece of metal ] you haven't come across before and the detector will determine how it should sound.
Similarly, there will be hundreds of [ variations ] in Targets that [ are known ] to produce 'said response Tones' but the make-up in the metal / metals (in the case of composites) will determine the Tone.
[ IF ] you are using a detector with a Meter ID screen, always pay full attention to ' new numbers' that haven't come up in the past AND, listen to the Tones and pay attention to 'gut feelings"

That's very well stated Des,especially the part about "gut feelings". If I've seen these "new numbers" a few times and the result is consistently a crown cap,one can make an assumption. Funny thing about gut feelings is they have to be developed over many hours of using the machine,and that's something that can't be taught....one has to find out for themselves!
Thanks for the input as always!
