Iron audio and volume (can report both ferrous and nonferrous)

[squirrel1]

Just a friendly reminder, with iron volume turned on, your deus can report both ferrous and nonferrous through the iron audio channel. It depends on your disc setting used and nonferrous target under your coil.

Hi Squirrel1, can you expound on this a bit? I am new to the Deus and don't quite get what you are saying. I understand Iron Volume and how it works and that you need some discrimination for it to work, but I'm not understanding the "iron audio channel" and how nonferrous signal would be reported through it.

Thanks,

Jeff

Alright, get a nickel, go to basic `1 program, turn your iron volume on, Sweep the nickel. You should see about 53 give or take. Next turn your iron vol off. Adjust your disc to say 56 (higher than the reading you obtained earlier on nickel sweep) . Now sweep nickel. You should hear no tone. Now turn on iron vol level 1 or 2. Sweep nickel, you should hear a tone (a low tone). The reason I mention this is some folks may be thinking while their using their deus machines, that any iron tones per se are infact iron. And depending on your disc setting and what you run your coil over this may not be the case. For example take a small piece of foil, it would read low VDI on your screen, and would not take as high a disc setting to put it in the iron tone category. And when hunting in iron pits, the same thing can happen, you may hear a low tone(iron tone) and depending on the masking going on and your disc setting (say you had it at 5 for example) may be too high to give a high tone say on a small gold ring being masked heavily. Clear as mud??

Squirrel1, thanks! These are the kinds of posts that ups the knowledge base!

Your welcome. I wish detector makers would stop using the terms iron volume/iron tone adjustment and start using the terms disc volume/disc tone adjustment. Because the terms iron tones, iron volume adjustments are misleading to the user.

I do believe I get it now. The affect of the combination of your disc settings and iron masking can make a low conductive non ferrous target sound off as iron.

Thanks.

Yes it can sound off for both but why would you want it to? On a steep sliding scale any Discrimination used above "10" will greatly affect the detection depth of the Deus. If you need Discrimination above "10" you should be using the Notch feature which has no effect on detection depth. It just removes the audio for the selected Range the Notch has been set for from the headphones. So you want to use some discrimination and you set it to "8" lets say and set your Iron Volume to "2" so you can hear when your around an area of activity. Then you could set the notch from "9" to lets say "30" and have quieted up the unit a little more and are still below most good targets in the USA. If you want absolute Quiet in the discrimination setting then set the Iron Volume to "0" and it will act like almost all other detectors out there.
I like a little Iron Volume so that I know whats going on under my feet without it blowing my ears off. Think of it as Threshold on a standard detector.
Using Discrimination on the Deus is to your advantage.

Once I figured this out it made no sense to me to have Disc set at 10, so I tried Disc = 2.0 and even in the bad irony areas, it's a bit more sensitive and sharp on non-ferrous hits. Seemed to push a little deeper while in Reactivity = 3 and had a little bit more sensitivity to targets on the edge of the coil. I think just a touch of Disc will help the horseshoe do its "ferrous/non-ferrous" dance over iffy targets a little more accurately.

Last week while hunting a homesite razed in the 1960s...I had Disc set at 0, and some iron targets sounded "non-ferrous", but at this homesite you "dig it all" since it's pasture. More on that next Monday!

I think some of the information above is faulty. You state notch doesn't affect depth. If your statement is true, then I should be able to do the following. Turn my deus on go to basic one. Sweep clad dime for air test distance. Measure. Note distance. Then notch out from 0 thru 2 points less than what clad dime reads when swept. Then repeat airtest distance and measure, note distance. From what your saying the measurements should be the same, correct. Guess what, on my Deus they are different?? Why??

I think I remember seeing this in the manual as well that notch does not reduce depth.

 

[squirrel1]

So go ahead Southwind and do an airtest and report back using my settings above. And watch the fringe depth differences. My deus with no notch in basic gives good solid tone at 10". I can hear some tone all the way to 12". Now with the notch I noted above, can get tone to 10". But no hints of tone past that. Differently different sounding at fringe air test depths.

 

[Southwind]

I just did. I used a silver dime that VDI's at 93. Taking notch up to 92 did make the sound a little less clear, kind of raspy, but did not affect depth at all. Depth was the same only the tone changed slightly. With notch below 91 there was no difference at all.

Please read the manual and book. It explains exactly what I have stated. There is no magic. These are electrical devices and they do what the manufacturer says they do. No more no less. It's in the manual. I'm out not going to argue.

 

[squirrel1]

I'm hearing slight/whisper tone with no notch at greater distance vs notch as stated above. For deep fringe targets, definitely could make a difference in hearing them.
BTW, I just looked at my Deus manual pg 15 and pg 40, in the notch sections. No mention of no depth lost.
And Andy's book pg 36 and pgs 82/83, again no mention of no lost depth when employing notch.

And concerning disc described in Deus manual pgs 9/10, again no mention of lost depth---we know there is though don't we.

OK hows a video sound?

[squirrel1]

How come you didn't sweep dime with both notch configurations out to fringe depths until tone/tone whisper drops out. This is where I see the differences, besides the overall tone quality (like it's broken some) using heavy notch. I have dug coins coins down to 11" that only give a whisper.
