No tones on deep targets

Regarding not hearing deep targets - in the CTX3030 Instruction manual (PDF) it notes that the Ferrous-Coin setting "may not always provide audio" (p41).

This is kind of misleading ( all targets that are masked that produce no audio from the coin that is covered by iron ) This would include all separation molds .
What they or talking about is in ferrous coin you may get 2 or 3 targets at once on your screen the strongest signal will get the audio the other signals will show up as traces on the screen.

Let's take a example a quarter under a nail the nail is placed over the quarter in a east west position .High trash ground coin and low trash will not leave you a trace of the coin on the screen only ferrous coin will but you will have no audio . If there is no trace that means the nail is killing the audio and the trace which will happen when the nail is larger or several nails are there .

The thing about high trash it says that a good target will give audio even if the bad target has a bigger response as long as the bad target is disc out . Now this is misleading to if the bad target is masking the good target so you get no audio from the good target you will not hear it .( This go's for all separation modes ) But at least in ferrous coin you can see it as a trace on the screen all other modes will be blind to it in audio and trace . The only thing you might get is a trace from the iron bin to the 12 line depending how well it is masked the heavier it is masked the shorter the trace to the 12 line but it still will not leave a blob on the 12 line .

Now if you have a coin that has a bigger response than the iron it will be a very good trace on the 12 line and if you look at the trace in the iron bin it will not be there or is very weak so the dime is effectively masking the nail or iron same can be said the other way around where the nail trace in the iron bin is strong and the iron false is strong on the 12 line but the coin trace is weak on the 12 line . sube

This brings up a question about Ferrous-Coin that's bothered me for awhile. I'm sure I've read more than once on this forum that Ferrous-Coin is not good in a nail-infested environment. Yet from what Sube writes above it seems that Ferrous-Coin is better than the other modes if hunting in nails. So... I'm confused Is Ferrous-Coin good for nail-riddled ground or not? If not, what situations should it be used in? Thanks.

Ferrous-Coin – coins in a high density FE trash environment, low mineralization.

Desirable targets they have a x for fe targets Meaning it don't like fe targets
Desirable targets they have a check mark for non-ferrous targets Meaning it likes non-fe targets
Undesirable junk they have a check mark for fe clutter Meaning it likes fe clutter
Undesirable junk they have a x for nonferrous clutter Meaning it don't like nonferrous clutter
Also for low mineralization
The first sentence confuses me then they say it likes fe clutter( what.) What's the difference here high density fe trash compared to fe clutter

This is right out of the manual This is the only mode that dose not like iron or as they would say fe targets confusing to say the least .
Let's look at ferrous coin separation what this means to me is it separates the ferrous target from the coin

Also something to think about low mineralization is where you use it If I run in auto plus 3 my sensitivity #s are 19 to 23 most of the time so I would say my ground is medium now the nail quarter well show in trace in ferrous coin but if I switch to ground coin it drives it to iron only a trace in the iron bin blind to the coin trace seen by ferrous coin . So in this situation it is doing what it says separating the iron from the coin leaving 2 traces on the screen . Looking at the chart they have ferrous coin is the only mode that has a x for fe targets .sube

Thanks, Sube, your explanation makes sense. I agree that the manual's description of Ferrous-Coin is really confusing!

I usually get sensitivity of 19-23 when running Auto+3 too, so my ground probably has about the same mineralization as yours. Good to know that Ferrous-Coin can handle it

If there are no mineralization issues with the grounds you are hunting is Ferrous Coin the best separation to use for deep targets while retaining tones, or should I try a high-trash, or ground coin?

I would use ferrous coin for a search pattern with my user key set to high trash for checking targets .

Ken this is how I see it but I have to say maybe because ferrous coin was to be used in low mineralization is why we are getting more falses on the 12 line but like I said before if I change to high thash or ground coin it will place the quarter nail hit in the iron bin . But the imfo from high trash and ferrous coin make a good combo to use . sube

Yeah... I have noticed more falses with Ferrous-Coin, and think I'll use my High Trash mode as the secondary program to cross-check signals. Thanks again.

You will get a little more falsing with FE-CO because that mode tries to push targets to the FE-12 line. That's why "iffy" coins become solid targets, but it also pulls more iron into the good zone too. Nothing is perfect and everything is a trade-off.

I think at running at manual +25 would be horrendous with the flasing.

about +20 i think is max for me.
