Video update how to know non-ferrous in iron

https://youtu.be/sy6EFkNjfZg I have been working on this for a while went on 3 hunts with good results 8 coins and 12 junk non-ferrous objects no iron dug yet. This works because of the Fe line and combine now I wonder if other machines will do this those machines with a tone break ?.

You can have your Fe line set anywhere as long as you can hear the nails they can't be disc out . But as I showed targets with audio well not give you a high tone if Fe line is set to low .Big iron will mask the silent hit and only give you a iron grunt it won't go silent because the ferrous item is stronger than the return of the non-ferrous target when there even or close to even the machine goes silent .

I had my sensitivity set on 4 that's why trace would not build on all targets it was set on 4 because I was doing other things and forgot to change it . Now you can id non-ferrous targets at disc depth and maybe deeper .

The way to run it in a pile of nails is to go to pinpoint sizing with target trace locate target then sweep with disc mode in several directions and see if it goes silent if it grunts both ways leave it if it goes silent or goes more quite than in pinpoint mode check it out . This also works with targets that have bad audio iron grunt with coin signal see if you can sweep it different ways to make it go silent at least you know it's non-ferrous instead of digging iron . But if you only get audio then that's how to check the target .

You can use this to hunt deep by digging by your depth meter but to get a true depth on the nail you must sweep the long way if you sweep the short way you will be 2 inches deeper than actual more to come . sube

Does that work with any size coil?

yes just using the 6 because my sand box is small. sube

Nice surface testing. I would like to see this testing in a aged test garden. Real curious how it would respond with halo's, different grounds and so on.

Sube-Would this also be accomplished by using an open screen and Smooth audio?

Yes as long as you can hear the nails in your disc pattern pitch hold and normal will work smooth and long will not I think it's because pitch hold and normal reset between targets and smooth and long do not , you can set your fe line where ever you want and will still work . sube

Ok thanks for the video,it’s interesting to see how things CAN react! The CTX is a magical machine for sure. I’m hoping that next year I can start getting into the real nuanced operation of it. It does so well with just basic operation that it’s easy to get complacent and just use what I use. It has SO much to offer. People who grouch about the price probably haven’t even made use of 10% of its capabilities. I think I might be up to 20%....:smile:
Thanks again for taking the time to make us think!

Sube, Thanks for posting the video. I was able to follow it until you started talking about not hearing the target when you changed to disc. I watched and did not see you hit the detect button to change to a discrimination pattern. Obviously I am missing something in the use of "disc". I am interested in trying this in our trashed filled local park. Thanks.

sube --

I watched the video; trying to understand a few things.

First off, are you saying that for this to work I have to HUNT in pinpoint mode, and when I find a target, then switch pinpoint mode OFF, and use my "disc" mode?

Then, I WAS hearing the "null" when you had the nail on top of the coin, and I see that without the coin, you'd get an iron grunt, but with the coin and nail, you got a "blank" or "null" in the audio. But, I have always had the idea that the only way to get a "null" is if you run the machine over a target that is discriminated out. So -- for me to understand this, I would have to know what disc. pattern you were running. You weren't running "open screen" were you -- i.e. combined, with NO discrimination? Because if you WERE, then that means that the machine is capable of "blanking the audio," or "nulling" NOT ONLY over a target that is being discriminated, but ALSO over a combined ferrous/non-ferrous target where NO DISCRIMINATION IS BEING USED. That fries my brain, if that's the case, so again -- what kind of "disc pattern" were you running there, when getting the "null" over the coin/nail?

IF you were running open screen, then I have some thinking to do...because "nulling" in an open-screen pattern is a new thought, for me.

And again, I'm still confused about whether you are saying that for this to work, you HUNT in PINPOINT mode, until you locate a target...

I took it as though he was running a pattern that allows you to hear iron instead of nulling. But when you have iron and a good signal ontop of each other even though you are running a open pattern you get it to null. Confuses the machine into nulling.

Jackalope -- that's kind of what I thought, too, but then he was talking a lot about sizing pinpoint...

I am running open screen 32 Fe line I explained why I run at 32 , ferrous coin sound (normal or pitch hold ) fast on you can run your Fe line anywhere okay , as long as you do not have the nails disc out . You have to hear the grunts from the nail other wise they will always be silent and there would be no difference from pinpoint sizing to your pattern your running . Now this is what I do set your machine up like normal what you hunt with but instead of hunting in your pattern just push the pinpoint button and locate a target now release the button and your back in your pattern to see if it go's silent then push the pinpoint button and locate the next target okay .

Steve what I think is happening is if you have a large iron object and a dime with it the machine well only see the iron object not confused same can be said if you have a dime and a small iron object close to the dime it well give audio for the dime but not the small iron with it there to close together but it well still display iron in the bottom corner and even if there's no iron with the dime it still displays iron in the bottom corner .This iron that is displayed in the bottom corner that's not with the dime is just ground minerals I think if you air test a dime then there well be nothing in the bottom corner okay.

Now a dime under a nail facing north and south to you will give the dimes audio but it's blended in all separation modes putting the cursor at 29.45 to 27.45 except ferrous coin which separates the iron from the nail and puts it on the 12 line .

Now let's look at combine there's 2 cursors one for iron and the other for non-ferrous these will be displayed on the screen okay . But you can't have audio for the two of them only one . So if you get a signal where the machine sees both targets stacked on top of each other or a dime under a nail running east west the machine can't give audio for either one so I think it just nulls ? your running combine but when the targets get to close and have the same return signal or close to the same it will not give audio another words it just goes silent . Then again if the iron signal is stronger than the dime to a point it will make the grunt grunt not as loud as if it was just a nail the dime has pulled the grunt grunt down same as a nail north south with a dime under it which displays at 29.45 instead of 12.45 . Unless your in ferrous coin which will put it on the 12 line but it well degrade the signal to 12.41 to 12.43 okay . sube

Steve,

I'm going to suggest that you may want to wait until you have some time under your belt on the 3030 and then revisit this one. LOL
