The Noise... THE NOISE!!

[Introfiant]

So, what do you do aside from digging to tell if the "signal" tone you are getting is a target next to/under iron, or just falsing iron?

They say to wiggle the coil back till its at the edge of the target and you will get some iron noise if its iron. I find that true for deep large iron, but the same happens when the noise is surrounded by iron and you wiggle it back till your over a different piece of iron.

Also seen turning 90 degrees and checking and if the tone is gone its just iron. But I've seen where a target was under nails and when the detector scanned parallel to the nails and target you cant pick up the target.


Seems a lot of the time I will get falsing from iron, and I'll do what I can to trying and see if it is a target next to iron or not but I can't tell yet. Still too new. So I dig and it ends up being Iron, or the target just dissapears all together... Feels like I'm back to using my CZ21 lol.

Just find it hard when youre in a lot of iron looking for targets with in the iron, and you're just getting iron falsing in with the targets. Little counter productive.

I found a small area from 1864 where the troops tossed about a dozen old tin ration cans out with horseshoes, a canteen and other misc. iron. I just sat down in the little 3' x 3' area and pulled all the iron out, along with a pristine eagle button. Only took about 20 minutes and had a blast. Dig the bigger iron.

If it's an older site with little or no modern trash, switch to full tones, move the frequency to 12 or 18, lower the Disc to 3.5 or lower and do not be afraid to raise the reactivity to 4 or 5, I see a lot of people say that's too high (even Andy) but in heavy iron (smaller iron like nails) it helps a ton without much depth loss. You will hear your good signal more "seperated" from the iron, but the signal will be much shorter or come and go faster, if that makes sense. Now if you're in big iron the only thing to do like Smokey mentioned is dig it up and get it out of the way.

yea it just seems with the reactivity higher the targets sound a lot like falsing iron. clips of a beep. Maybe actual targets have a louder tone than the fasling iron does? Just seems the deep targets are so quiet anyways it's hard to tell what the machine is saying. With time I suppose.

 

[Tedyoh]

"Clips of a beep" is what i dig with high reactivity in heavy iron, this is what good targets sound like in iron and high reactivity settings, just shows itself quickly.... Is it big iron or small iron you are getting tricked on? Also detecting in full tones helps with iron falsing, make that switch now of you haven't already....

Loudness of the various tones can be infinitely adjusted through expert settings such as # of tones, iron volume, silencer, and audio response. With some expert input ( e.g., Andy Sabisch's handbook, advice you get here) you can make even the "clipped" good tones in high reactivity setups pop out of the iron low tones. Also, I think a lot of folks forget about iron wraparound at the high vdi numbers (97 - 99) and forget to manually set a permanent notch there to supress false high tones from iron.

I found this secret. It has helped me. It may be helpful to you. Let me know if you like it.

 

[Introfiant]

i've got the 97-99 notched. seems its nails, and long iron that the machine falses on mostly. But it's high trash area so i just dig and see. Usually end up with some small thin piece of iron.

 

[gene the machine]

nice demonstration... thanks... i've know about the X Y screen but haven't used it but i will now...

 

[DeepseekerADS]

Let me know if you like it.

I don't have a Deus, but I'm quite impressed by what you show on your video! Maybe my CTX has something like that hidden in that vast set of options....

 

[Tedyoh]

This is a good video but you should only use the X/Y screen if you are, or think you are on, an isolated single target, a coin or good relic next to iron will give you a jumbled line and you, in theory, will not dig.

 

[vabuckhunter]

Dont notch those higher numbers, I run 12 KHz most of the time and have had deep bullets and a deep large cent come in at 98 99. As for using the XY screen I think its quicker to just dig the target and move on rather than trying to distinguish whether its good or not.

Relic hunting, I agree would not notch and would give myself some iron volume. In fact, in mineralized soil I would probably go with gold field which is the closest that Deus gets to all metal mode with the current software. Coinshooting I would generally go with the notch, that does not keep the vdi from displaying but I would definitely set up a no notch program in advance so that I could switch between the two as I became aware of what type of site I was dealing with and the types of targets that were being retrieved. Yep, would hate to miss that deep large cent just because of a notch, but sometimes, digging all targets is just not practical due to time limits or other considerations.

Another trick vs. X-Y to distinguish between a true and false (e.g., rusted bottlecap target) high vdi number target is to just switch to a lower frequency. If the target is legit, the vdi number will generally go down with the lower frequency (vdi numbers for the same object go up with the higher frequencies). If the vdi number goes up with lower frequency, good chance it is junk like a rusted bottlecap. But like buckhunter says, the only way you can be 100% sure is to dig all targets. Detecting involves weighing the risk of a missed find vs. the time you have to scan a the ground you are on. The tradeoff is perhaps recovering several good targets and missing that one great find on the other hand, you can dig all targets, get a pouch full of junk, but that one find of a lifetime. Its those tradeoffs and knowing you made the right choice for the situation at hand that makes the hobby a blast for me.

If there is one thing I have learned from detecting, there are relatively few "absolutes" and a lot of "it depends". I agree that setting the high vdi notch is not suitable for all situations just as I think giving advice to NEVER use the notch would also not necessarily be the best way to go. The best thing people can do is put the info out there and let people decide based on trial and error and experience what works best for them. You can always find real life examples that counter any specific advice given on forums or in books, the key is deciding yourself what works best for you. 10 minutes in the field or experimenting with settings on a test garden probably beats 1 hour of reading forum advice because the key to detecting is developing the muscle memory or developing the ear to hear that faint, clipped tone that is your dream find.

Thanks for the advice guys. I've been using the deus like a mad man and am coming along pretty good with it. One issue i'm having with it is I can't get the machine stable in any of the frequencies but the 18kh. It runs nice and if I lift the coil up I don't get a crap ton of noise. But if I use it in any of the other frequencies it drives me nuts. I am in the woods, not near power lines or buildings, sensitivity is at 90. I've tried offsetting the frequencies as well with no luck. It's rather frustrating and I'm about to send the coil in to have it checked out. Ground balance is on tracking, i've tried manual as well. TX power at 2. I can't figure it out.

Anyone near you with another coil you can try? Do you have the same problem when air-testing in a sterile environment? Does this occur using the stock programs? I'd call Moe at XP and see what he says....some EMI is expected, but not all the time everywhere you go.

When the coil is in the air its just as bad if not worse. It sounds like EMI and in 18kh its quiet. When the coil is to the ground or in the air its just chatty cathy. I'll try it out this evening in the stock programs and see if I still get the noise. No one around here I know of that has one. And I like it that way lol

My first coil started acting like that last year; had to send in; Moe sent me a new one.

I'd hate to deal with that but I just bought the thing a few weeks ago. It's always been a bit of a pain in all the freqs but 18. Who is Moe and what should I do to talk to them? Or should I contact the people I bought the machine from?

I've found that a lot of dealers (not all) will simply refer you to:

The complete XP DEUS metal detector is covered by a five year parts and labor warranty for detectors purchased on or after January 1, 2013. Units purchased prior to this date are covered by a 2 Year Parts and Labor Warranty.

Ask for Moe....a very good technician in the service department. He should be able to help you over the phone, but if he suspects there's a problem, he'll have you send your coil, remote and headphone puck to him. It won't take very long at all...better to do it now if necessary than wait for the weather to really get nice :-)

While sending the coil in is an option, before you do that I would still try a lot of other things. if you haven't already, read my post http://www.treasurenet.com/forums/deus/487970-how-deal-emi.html#post4853408 in the emi thread. You are doing all the right things but be sure you initialize the deus with the coil in the air. Try knocking down sensitivity a few points. You are not going to lose signficant depth unless you really need to dial it down closer to 80 or below. That might signal a hardware problem. Check that silencer is not at -1 and keep reactivity around 2 or 3 but dial it down to 1 if necessary (still faster than any machine out there at that setting). Be aware, however of the silencer "gotcha", where it changes back to its default when you change reactivity (its in my post referenced above). If you are still not getting relief from the noise after trying out all these things, then you should consider service. Good luck.
