So what can REACTIVITY do for you?

[Andy Sabisch]

Here is an example of how the enhanced Reactivity function can open up areas that other detectors either can't handle or run away from in frustration.

On the way to an old home site this afternoon I passed a school and thought I'd stop and do some comparison testing with the V3.0 and a few other detectors I had in the truck.

The area by the front door is usually a good target-rich area and was I ever right at this site . . . . it was literally one continuous carpet of signals . . . pull tabs, screw caps, coins, tin foil and other junk was everywhere. I spent more time that I had intended to here and only searched the area within the borders in the photo below. I started by checking targets with two other detectors but the stock coil on one and a smaller after-market coil on the other still struggled to get a good target from amongst the trash. You can see just how small the area was.

I bumped the Reactivity to "3" and then to "4" and slowed the sweep speed down . . . . and in doing so, individual targets could easily be separated from adjacent targets and with a little on-the-fly adjustment of the audio tones in 5-Tones, good targets were easily pulled from the trash. I tried FULL TONES now and then but in this area, a dig / no-dig option with 5-Tones setup for what I was looking for worked better.

The results . . . . 52 coins including 9 nickels, only one crushed rusted bottle cap, a number of the square pull tabs that hit exactly where the nickels did and a few odd trinkets . . . . and that was about all the trash. Talk about "cherry picking"!

The response was clearly different then what I had been used to with the Reactivity at "4" but targets were isolated with this setting and a little "learning" paid off . . . .

No piles of silver but it showed what a change in setting could do in a specific area and for a specific challenge

Andy,

Great information on the Reactivity settings. Which program were you using and what were the individual settings? Many thanks.

One thing I tend to avoid is focusing on a Program name when I discuss what I use in the field . . . . for example, what I was using yesterday was the COINS 2 programs with some changes that took less than 30 seconds to make once I started hunting and saw what the site held.

No before everyone starts scratching their head wondering where the COINS 2 program is on their Deus, its not one of the predefined programs but rather one of a number of programs I have built to fit specific needs.

I took two guys out the weekend before last who were interested in seeing the Deus and they asked about the named programs that I had in slots 11 - 18 . . . . and I explained they were constructed in short order for sites in the local area.

Once you really know what each function does, creating programs is a snap and you will find that the predefined programs are either ones you use without any changes or use very little since making the Deus a "turn-on-and-go" detector is pretty easy (Hmm....sounds like a chapter in the new book )

As far as the settings I used at the school site which I modified to fit the trashy conditions starting with my COINS 2 program, here is what I was running

([size=large]NOTE[/size]: Stopped by today again and puilled another pouch full and made some changes . . . here are the settings I settled in on)

FREQ: 12 kHz
DISC: 10
IRON VOL: 0 (not interested in the presence of iron)
REACTIVITY: 3 and then increased to 4 in the bad sections
SENSITIVITY: 80 (no point in overloading on the shallow trash and based on pulling a 1944 Mercury dime at 7", it was still getting the depth)
SILENCER: 2
AUDIO R: 3 (decreased from the usual 5) - did not need the amplification based on the depth targets were being recovered from
BREAK POINTS: 10, 48, 56, 72
TONES: Set to make the coin regions (49 to 56 and 73+) produce a DIG signal. I set the tones for the 10-48 and 57 to 72 at a lower value which made the coins a snap to pick out


When I was done with the changes and tweaks in the field yesterday, I saved them as COINS ST and will have it available for another (S)uper (T)rashy site I might come across.

The key I found in the high trash was to slow down and the good signals are much easier to hear - they sort of jump out of the chatter - no way to miss them when you hit them.

So between yesterday (with 52 coins) and today (another 74 coins including 13 nickels and what I will claim is a diamond tie tack in the center of the photo . . . only kidding), the flexibility of the Deus and the ability to pull keepers from areas that others tend to avoid, judicious use of Reactivity and audio discrimination pays off.

Hope this makes sense

Very interesting. A couple of questions before I try this in my trashy park...
* What tone/sound do you apply to 97+? Do you make it the same as your <10? or 11-50?
* Why the 50 - 57 range? For nickels? And some gold?
* If really focused on coins, why start the next section @ 70? Pennies typically are 75+ @ 12Khz (in my limited experience!). So is this to capture small silver jewelry? Or is this one of those cases of interactions that makes that lower break point more important?
* Last thing -- surprised at silencer @ 2. Do you hear the buzz well enough at that level to separate out the crown caps?

As you said, obviously this is a starting point, and in field adjustments may be necessary (or personal preference). But was really interested in those setting per my questions.
Thanks!
Rich

* What tone/sound do you apply to 97+? Do you make it the same as your <10? or 11-50?

I assign it the IRON tone which is the <10 value - nothing good that I have been looking for has hit at this point or higher in 12 kHz - it is rusted iron 99.9% of the time.

* Why the 50 - 57 range? For nickels? And some gold?

Nickels . . . . and of course I will take the gold if it shows up

* If really focused on coins, why start the next section @ 70? Pennies typically are 75+ @ 12Khz (in my limited experience!). So is this to capture small silver jewelry? Or is this one of those cases of interactions that makes that lower break point more important?

What you will find is that in high trash areas, TID's tend to be pulled down slightly and this is especially true for deeper targets, The school I was hunting was built in the 40's and I have found some wheats and silver there before so I was hedging my odds and used the TID along with the depth indicatio to determine if a signal was worth recovering . . . . and not that they are really worth recovering but those zinc half or 3/4 pennies tend to read in the lower 70s :blush:

---

* Last thing -- surprised at silencer @ 2. Do you hear the buzz well enough at that level to separate out the crown caps?

Yes, a combination of the sound and another trick . . . . . . but depending on the type of cap, a Silencer of "4" works as well - I have found that it works on some but not all in terms of rejecting them audibly . . . . have not figured out why two that look alike act so differently - may pack some up and send them to France for XP to review

Tones on your settings to produce digable signals, did you use program 10 as it says tone function is available only in the Gold Field program or are you talking about something else for tones?

Sorry . . . what I mean is the audio response for each of the segments defined under the EXPERT menu after you select 5 TONES.

I revised the post to reflect the way each window was set to respond

Let me know if this cleared it up or made it muddier

See if this clarifies things . . . . . with the addtion of a NOTCH window

I tried out this "ST" program yesterday for a short hunt. I liked it very much. It helped me to bump up the silencer to 3. Even then I wasn't sure about a couple of targets, but then I'd switch to a program with the freq at 4k where bottle caps register in the 90s. So that was a nice quick and easy check. I still dug a few as a check. I think I only dug 1 unintentionally, which was a huge improvement. Was also able to slowly go over tightly grouped objects and hear them clearly, or figure out the 2 different signals I was getting.

I walked away with $2.95 in clad. No silver but 3 wheaties. Gotta say that I'm starting to feel that I'm "getting" what the Deus is trying to tell me.

It was fun and exciting, and I'm looking forward to more with the Deus. Andy, thanks for posting this and explaining the settings in detail. That was very helpful.

Concerning "break points/Notches" ......are the numbers up to and including or up to not including or is one digit significant?

Never mind, I think I found the answer......Pg. 37.........:

Hi Andy,
you're graph is so amazing for a french guy because it illustrate your comment, each spot has its specific "programs", for example, today I focused on one type of coin that we are fond of in south of france (oboles, very small coins, so I made my own graph here:

The funny thing is that you're notching all good items here in france, there's such a difference between our countries, its amazing, but everybody needs to know that each place is specific and we have to adjust our programs everytime according to : what we want to find, soil's nature, ferrous or not, etc. It's the same problem all around the world for the MD people.

Thx for sharing your experience Andy!

 

[slow'ndown]

Question for Andy or anyone else that could help. If you can bear with me, this is a 3 part question.

1) First, a general question regarding discrimination and notch. Do these have the same effect on the machine? In other words, when you set a notch, is that essentially the same as a discrimination setting? Just curious.

2) In your coins program, since the goal is primarily to dig only coins, why not also set a notch for the 10 to 48 window (or just extend the discrimination range)?

3) Now for the tough one (at least for my over 60 mind)! I wanted to try this program and successfully applied all the settings as indicated, and set notch windows for 57-70, and 97-99. The problem occurs when I try to set all of the tones. In your diagram, you don't include a tone setting for the notch window of 57-70. However, in the 5 tone option, the notch doesn't "show up" and thus I can't find a way to avoid setting a tone for this window also. I also thus can't differentiate the 97-99 notch with a separate tone. There is probably a simple explanation for this but right now I'm really confused. Any help to set me on the right path would be appreciated.

Yes, but higher levels of discrimination will cost you detection depth while Notch windows will not impact your detection depth . . . . run as low as possible with the Deus in terms of Disc - for US hunters, "10" works with other settings

---

2) In your coins program, since the goal is primarily to dig only coins, why not also set a notch for the 10 to 48 window (or just extend the discrimination range)?

Extending the DIsc to 48 costs detection depth. Depending on the targets present, I may opt to dig some in that lower range and with the tones set where they are I can decide if I want to dig them or not

The Notch will reject or ignore targets in that range to tones are irrelevant. YOu need to go back out of the DISC Expert menu to the NOTCH menu and then go to Expert there and set the window you want

If this is still not clear, let me know and I will try to get in touch with you (PM --> phone) to clarify the setting of this program

[rks1040]

Are you using NORM ID---YES? in this program?

 

[Andy Sabisch]

Are you using NORM ID---YES? in this program?

No, for most of the hunting I do, I do not use ID NORM . . . . I see more benefits to having the TID values shift at different frequencies and the shift differs based on the target so that helps eliminate digging some trash that woudl otherwise be recovered

Andy

 

[rks1040]

Thanks,Andy! I tried the program this morning and dug 3.71 in clad in 1 1/2 hours. I did dig a lot of trash also showing up in the high 80's on the TID! When you make small changes to a custom program,can you just save the program again,to keep the settings? I'm getting used to V3.1,I didn't like the tones compared to V3.0,but I can't seem to be able to reinstall V3.0 again,as the only two options on the download site's drop down box ar V2,and V3.1! Both have the same tones. I liked the "clipped" sounds in V3.0

 

[AIRFORCEMIKE]

I just love that program!! just made the tweak Andy updated and still runs like a champ and I am still getting targets at 6 - 7 inches. I run this program in all my tearouts and it just simply purrs...not chatter nothing. I also duplicated it in another slot in 18 for quick switch to verify BC's

 

[Henrikras]

Hey in the US.
Maybee there is something in this I posted i UK, there could help a little.

Hey Guys.
Made this video to hear and see the different 3.1 / 2.0 - You can do some fast forward and rewind in the video, first; not to wait while I'm Downgrade til 2,0 - and second to compair the 3.1 / 2.0 the best way ( find the spot GMP 3.1 start and the GMP 2.0 and swich ).
I dosn't feel the 3.1 gave me advance in the field, now after the Video I really can see that in Deus fast, the old 2.0 is much better, is more difficult to deside in GMPower. Is the Sound more smooth in 2.0 ? And isn't the ID more stabile in 2.0 ??? And the miniralization level ! In 2.0 its seem to reset faster???

Henrik.

[Sweepstakes]

Thanks, Henrik, that was an interesting comparison. I have been trying to decipher the differences since I downloaded V3.1 and in my last outing , in very wet ground conditions, gave me my best coin day yet, in a school yard setting. I wouldn't give up on the V3 changes too soon, as the TId is often not as important as the sound signals. What I do see from your experiment is not to give up too soon on TIds that jump around, but tend to indicate a good find.

 

[Terry(Mi)]

Good vid and basically mirrors what mine does. I don't care for the clipped sounding deeper targets on v3.1. I feel the tonal hints favor 2.0 for the deeper keepers, and that's with the 9" coil.

3.1 does seem to run better in iron with a lower (1) reactivity. I also like the speed 3.1 has flipping through the programs, but overall I'm sticking with 2.0 for the season
