Deus 2 VDI

[Bucktrout]

I‘ve had the D2 for all of about 3 weeks now. I have been running Rattleheads silver slayer program( Rattlehead if you’re reading this thank you for posting that program) I am not bashing the D2 in anyway, because it has brought life back to some very hunted sites.
Can anyone explain why copper Lincoln’s, clad dimes and silver dimes all be coming in at 91-92? I also had a Franklin half come in the same as clad quarters. I love it’s ability to sniff out the coins but good grief I never know what I am going to dig up. Is this normal or am I the only one experiencing this? Thanks for any help.

Higher conductive coins can come in different. Could be driven by orientation, masking, etc.
Btw I have seen copper pennies come in as low as 83.
Remember sites that have been hunted hard. What’s left has high chance of having something wrong with it. Deus 2 can sniff out.
Worn coins too can give lower readings than standard.
Your speed (reactivity) setting can drive too depending.

The same thing you get with the Nox and Legend. D2 is no different.

The Deus 2 definitely has coins in that range bunched closer together than some other machines, like the Manticore for example. Having them close together has some advantages and disadvantages. One of the advantages is that you’ll get a more stable ID, even on deeper targets. This allows you to run more notch without so much worry about missing targets due to the ID constantly bouncing around. The disadvantage is what you already mentioned, certain coins being grouped so close together that it can sometimes be difficult to tell them apart.

I usually just dig TID ranges and don’t worry much about a specific digit being off by a point or two. If running a program like Silver Slayer, I’m already using a lot of notch to eliminate a lot of targets in the junk range… So if I hear it, I’m digging it, regardless of the ID.

Keep in mind, the Silver Slayer program is for cherry picking. You will miss some handicapped targets with it, as nearby maskers will drag down the ID. Worn silver can also read below the notch. It’s a trade off. You’re knowingly giving up some challenged targets in exchange for digging less trash. You increase the odds of more good targets per time spent detecting.

If I’m on a site that’s been pounded, I’ll usually lower that second notch down to around 78. This will unlock a lot of semi-masked coins, as well as worn silvers, and some lower reading coins like IHPs.

I have noticed this tendency for the Legend, Equinox models and Deus 2.

Depending on soil moisture and ground balance number using Deus 2, I have had clad and silver dimes be 89/90/91 one day and 91/92/93 the next. The same goes for copper Memorial pennies. One day I can count on them to be 91/92 and the next 88/89/90.

I don't mind digging modern US coins so its no big deal for me. There is plenty of it where I detect so it's all money and worth something and it all adds up in the long run.

If I was trying to avoid clad dimes and copper pennies and just dig silver US dimes using Deus 2.........good luck with that.

It's no better with the Equinox models and the Legend where I most often detect.

 

[Rattlehead]

One method I like to use to avoid clad is depth. On a new site, I dig everything for the first half hour or so, just to get a good idea of how deep the older stuff is running, then I start cherry picking only signals at that depth range and beyond. It’s not perfect, but it sure helps eliminate digging so much clad.

Very easy to set up adjacent programs on deus 2. One with higher audio response to get over targets, and adjacent program with lower audio response. To check for deeper targets. I like this capability with deus 2 being able to navigate and check targets. I use other methods too. Even different programs.

 

[Bucktrout]

Thank you all for the response. So its the nature of the machine to “clump” all the coin signals together- and it will vary depending on certain soil moisture and such. Makes sense. I just wanted to be sure I was understanding the machine correctly.

Do you use the 11" coil or 9"? I use the 9" and have no problems telling even a copper from a zinc penny much less a dime from a penny.

I think as has been suggested conditions have a big influence on the VDI of the Deus 2. Rumor has it that they plan to fix the VDI normalization and the VDI showing the iron VDI, 06-08, and not the coin VDI when the two are in the same hole.

What I have found interesting is even though the VDI doesn't show the correct numbers for a deep coin sometimes, the Deus 2 still will hit them but just show a low VDI. I use a program in our city park that is just for silver. I have the discrimination at 87. The VDI won't show a number of 87 or higher, but it will sound off good and clear. That tells me the coin was being masked.

Copper pennies and silver dimes are just too close in conductivity and size for a detector to distinguish between the two. Throw in all the other variables, and good luck trying to do that.

If there was detector that would only sound off on silver coins, I would buy it today. Too bad such a detector doesn't exist. I could notch out the copper and zinc pennies, but I would cry about all those missed silver dimes.

Truth. Depending on the orientation of the coin, moisture of the ground and depth all the major detectors will show higher or lower VDI's. Both my Nox and Legend go deeper than I want to dig, sometimes show a zinc penny or dime as a quarter but will let me know somethings there. Saying one machine is better with these conditions is pure hogwash.

I bave the 9 inch coil. I went to another park, and I could distinguish between a clad dime-91 and a barber dime- 92. I agree that it certainly is capable of sniffing out masked coins that my ctx and nox missed. If it rings up high enough I dig it, I guess I am just used to being able to know what coin I am digging like with the ctx. D2 is a bit more mystery on what is going to come out of the ground. Could be it was just the conditions at the one park.

 

[rreahard]

I can usually tell the difference between a copper penny and a clad dime, sometimes I cant. As they say - when in doubt, dig it out!

 

[Rattlehead]

If it rings up high enough I dig it,

That's the idea.

At most locations, non-worn coins with no contamination usually read something like this for me:

Wheats: 86-90 (depending on year)
Copper Memorials: 89-99 (these tend to up-average like crazy for some reason).
Zincs: All over the place. But, well below the 87 notch.
Clad Dime: 90-91
Silver Rosie: 91-93
Merc: 92-93
Barber Dime: 90-92
Seated Dime: 89-91
Clad Quarter: 94-95
Silver Quarter: 95-97

Of course, those numbers can change considerably depending on the ground conditions, coin condition and nearby contamination effecting the signal. Best bet is to do like you said and dig everything above the notch without worrying too much about the numbers being off by a digit or two one way or the other. Even though some dimes may read lower depending on conditions, you can still get excited when you see that 92 or 93 pop up in the window, as there's a good chance that's a silver!

Great posts Rattlehead and others.

Even out here in Colorado where the dirt can be absolutely insane, the numbers you posted are fairly consistent with what I am seeing. However, those numbers are only dependable using Deus 2's simultaneous multi frequency modes on targets from surface to the edge of detection out here.

I mostly use the Standard display screen and really depend on the non-ferrous signal strength meter to help with shallow versus deep targets. Some places where I detect the surface to near surface aluminum and steel alloy trash levels are so bad that I don't use that meter much......I'm just lucky to pick any decent non-ferrous target out of that trash. Other places here where the soil is finer and more sandy, 2010 and later Shield zinc pennies and the most recent oval pull tabs are often 6 to 8" deep so just concentrating on deep coin sized target signals doesn't always pay off. Other places here, bedrock or hard clay layers are fairly close to the surface and coins that penetrate those layers are usually on edge so using the meter makes them seem a lot deeper.....crazy. Add in lots of magnetite and volcanic material which isn't evenly distributed but instead collected or blew wherever and things can get even more interesting.

The really good news is Deus 2 can handle all of those situations even with its 9" coil. I am really grateful that XP worked so hard to really improve their Deus line of detectors so that Deus 2 could happen.

I really appreciate topics like this where everybody can contribute without a ruckus. Thanks to the original poster for starting it.

You can imagine how excited I was when I was digging what I thought was a clad quarter coming in at 95 and found a silver half at the bottom of my plug.

It’s a probability Number. The numbers can vary a little. Like nickels come in at a range of 58- 64 . Part of not knowing exactly what is under the coil makes it part of the fun. Try to go with audio first then add the number to the mix .

 

[Bucktrout]

Thanks Tony. Thats what I’m working on, really learning the audio.
