Air testing a 4kHz program...

[CZconnoisseur]

Hello again - Before I get going tonight I air-tested the same coins using a 4 kHz program suggested by DukeOBass. I must say - even with the Reactivity on "2" and Silencer on "0" Deus was ultra-sensitive to the coins, and the EMI was about the same intensity as last night's test.

Settings are: 4 kHz, Sens = 83, Disc = 4.0, Reactivity = 2, Silencer = 0, Iron Vol = 0, Audio Response = 3, Overload = 2, Notch 0-30 and 94-99, GB = 83, Ground Notch = 84=90, TX = 3


Here we go:

15mm aluminum token..................................................8"

18mm 90% silver dime.................................................9.5"

19mm Indian head cent................................................10"

21mm Nickel.................................................................8.5"

24mm 90% silver quarter.............................................12.5"

30mm 90% silver half..................................................13.5"

So - let's give these settings some real-world testing and I will report back in 3-4 hours!!!!

Wow. Really interesting. I've never experienced that in the field. I mostly use 12 kHz with a 4 kHz program adjacent. That 4 kHz program has disc @ 0, reactivity = 1, silencer = 0, and the sensitivity ~92. When the 12 kHz is set up similarly (except disc = 6), the horseshoe showing depth is always shows me that the target is shallower than the 4 kHz program. When I bump the 12 kHz to reactivity = 2, then they show about equal on the depth gauge. So I'll be very interested in seeing your results from tonight. In fact, when trying similar programs at different frequencies, it is always the 18 kHz that shows the greatest relative depth. I still prefer hunting in 12 kHz, but that's been my experience with respect to depth.
Take care,
Rich

Thats almost my silver setting. 4khz gets rid of rusted items and is hot on silver.

OK so I spent a little over 2 hours last night with the new-to-me 4 kHz program and looked for deep targets - first in a relatively clean section of the fairgrounds followed by bottlecap heaven - and the results are very promising. I only dug 5 coins - all pennies; 4 memorials and one toasted Wheat. The deepest coin was a 1963 memorial at 6" down - it sounded like a 3-4" deep coin initially - was surprised to see it deeper in the hole after I cut a plug. The other pennies were less than 3" deep and were BOOMING signals - I will have to get used to the different audio signal while hunting in Reactivity = 2 and 4 Khz - every high-conducting target it seems to slightly overamplify, but this means to me that the deeper goodies will be more easily detected

Separating deep ferrous fron deep non-ferrous targets is MUCH improved with 4 kHz, not once last night did I dig a large chunk of iron at 12" down or more! This program really knocks out the deep iron and I feel that once I get over some silver it will really let me know! I rechecked a couple of iffy targets in 8K and 12K programs, but in those higher frequencies the target "sounded" better, but switching to 4 khz there was nothing good about the signal...saving me from a lot of frustrating deep junk. I did also manage a screwcap at 9" and 2 others at 6-7" deep - all three screwcaps registered 58 to 61 on the VDI and were fairly steady, so in the future those should be easy to call. Too bad they register almost the same as an Indian Cent

The best sounding target was a faint "85" which turned out to be a small brass fitting at 9" down. It sounded so different than the surrounding chatter it was unmistakeably a "dig". Dug a couple piece of solid copper thick wire at 4-6", but wire usually sounds great in one direction, and iffy at 90 degrees but with a lower VDI. Very rarely do coins sound like this, but some do and I dig signals like this anyway...many times it's a Wheat hiding underneath a couple of old nails.

I need more time in the field and more time to get at those deep non-ferrous targets - but my first impression is that this program may be the "goto" for the fairgrounds where bulldozers, race cars, horses, and countless people have roamed for the last 150 plus years! There HAS to be Barbers and older coins just waiting to be found - just need to find that area that got slightly covered by fill dirt and listen for the squeaks - but if this program works this well at squelching deep iron then that is a major obstacle overcome at that site!

4k is nice and deep. It will spare you digging iron. It also does away with a bunch of EMI. You can lower your Disc down to 1 or 2 and notch up to 30. That way you won't miss nickels. I have been digging very deep wheaties at heavily hunted locations. If the deep target is a definite "digger" it will repeat in both directions and be undoubtable.

Just curious, how deep have you been finding those Wheats? I've never retrieved a coin below 9" with the Deus so far, and I know it's capable of much more!!!!

 

[DukeOBass]

I would say 11". I have my Audio Response set at 4 so I get a more faint audio when I have a deep target. With 4k, Reactivity 2 and Silencer 0, the shallow stuff really screams. My first silver coin screamed like I had never heard silver scream before!

Hey CZ, thanks for the update. That's awesome info to hear. I will update my 4 kHz program to something closer to what you are using and see how that works out for me.

Here's a potentially helpful hint if it hasn't already occurred to you: use a 8 or 12 kHz program (whichever one you feel you "know" the IDs better) as a "reverse check". I say reverse check because we've been using the 4 kHz program as a way to check bottlecaps when using the 12 kHz programs. This works pretty well when you know a specific area really well, like you apparently know this fairground.

Let me give you an example. Nickels seem to have the widest range of good signals for me in my ground, even when I'm carefully GB correctly. In 12 kHz, have seen as low as 51 and as high as 55 (maybe 1 56). when I flip to 4 kHz, they are in a narrower range (counterintuitive given that the lower frequency gives you a wider spread on lower IDs, but that's been my experience) of 38-39, and a couple at 40. Partial beavertail pull tabs will give me a 51 - 53. So I flip over to 4 kHz, and they come up above 40, usually 41 or 42. Sometimes I'll still dig it, but if I'm on a short hunt or tired, I feel more confident passing up that signal believing it not to be a nickel. But to learn that took digging up many of those suckers! And soon you come to recognize that pattern.

I suspect that if you keep hunting in 4 kHz, and check some of those signals in 12 kHz you'll begin to see similar patterns that might make you feel more comfortable about not digging them, depending on the situation.

Continued good luck, and please keep updating us. Thanks!
Rich

Thank you for the tips Rich! I do in fact have my goto 8 kHz and 12 kHz programs one and two spaces, respectively, away from my new 4 kHz program. So on an iffy target a quick jump into either program should raise the VDI for a target, opposite the bottlecap checking method. On deep targets the signal should go away, or become very blippy if it's out of VDI range in 4 kHz. If it's an iron target I would think that the audio quality would get better if it's a mere squeak in 4 kHz since the higher frequencies have more of an affinity for deep iron.

Tonight if I can hack it - I will be hitting the roller coaster area - an area with tons of deep iron contamination and see what crops up. This is also where I've found the two barber dimes - the only two in my life - as well as a handful of Mercs and Rosies from 1-6" deep. Kinda makes me wonder what's deeper...

I went out yesterday using very similar 4KHz program to yours (CZ) and used the XY and a 12KHz (adjacent) to check for caps. I was fooled a couple of times by rusty caps using the 2 different programs. The XY worked nicely though I dug everything to test the method. I dug some clad, 3 wheaties and an another 1908 IH. All 4 older coins were about 4" but sounded like they where on the surface. I did notice that after checking one of the wheaties (before it was dug) that it was a bit scrambled on the XY, perhaps there was something else there but I never found it.

If you found barbers than there are more of the older coins for your finding. Good luck!

Aha! jspeedy you just reminded me why I hardly ever use the XY program anymore! For a while I was checking targets with the XY visualization, and I almost didn't dig one of my buffalo (or V) nickels because of that scrambled view. I dug it anyhow, luckily. But that was when I realized that iron co-located with a target could result in a mixed message. I don't recall their being a dominant line AND some scrambling. Maybe there was and that's why I dug, or maybe because it just sounded good. I will use it some over the weekend to see if I can notice any patterns that might help me in interpreting some targets for the future.
Thanks,
Rich

Hey Speedy or CZ, I am going out in the morning (sunrise) here in Arizona and want to try the 4Khz can one or both you post your settings so I can load it tonight? I usually use 12 but now you guys got me curious about using 4.........

I am going to 2 heavily hunted, heavily junky places. I have done very well with the 12 in these 2 places and figure to give the 4 a try and see if anything left.....

I really need to take notes in the field, I always think I will remember the signals and VDI after but I NEVER do......Maybe a notebook and pen this time so I can report back.....


Thanks in advance!

Jim

PS let me say thanks also for the EXCELLENT posts you 2 do, always good info and that sure saves me a ton of trial and error, appreciate it guys.

Thanks CZ, will try it in the morning.......

[parkgt]

CZ,

Why do you feel the need for the ground notch? Is it that you have "hot" rocks in your area or is it a function you use all the time?

 

[jspeedy]

4KHZ, sen=90, disc=10, react=2, silencer=0, iron vol=2, audio=3, overload=1, 11-61 low tone, 62-92 high tone, 93-99 notched

 

[DukeOBass]

If you're coin hunting, notch out 0 to 30 and drop your Disc way down to around 1 or 2. You'll gain depth and speed.

 

[Sleepyjim]

Thanks speedy!

Well it is after midnight and in 5 hours I am to get up but the weather is sucking now, and calling for rain and 45mph winds....LOL never rains the desert my butt!!!

So now I am most likely shut out for detecting.......

Friggin rain.......

Thanks Duke I'll give it a go.

 

[jspeedy]

I made the changes to my 4KHz program and air tested a silver Washington at 14" and a silver rosie at 12". It's raining but I'm going out hunting anyhow to try the program.
