Could Not Make Eqx To See The Target

Recommended Posts

Hi All,

First post, please do not judge... Question to more experienced EQ 800 users. I have been detecting for over half a year now, got piles of questions I can't seem to find a definitive answers, so decided to register and ask instead. I also want to highlight I'm interested in all relics, not just coins. Thanks in advance.

Long story short, I have 2 things to ask about, these are sitting for quite a while in my head and can't seem to figure it out. First and probably most asked is the firmware version. I have tried all 3 versions (with proper resets before and after) and my suspicions are that the oldest is the most neutral to the other newer ones - most suited to "all" detecting. Newer ones' frequency response is not as flat, but equalized if I can express this way. The newer it gets, more biased towards coins and larger objects it seems to appear. For example, with stock 11" coil, on fw 1.5 I could detect items as small as pistol round lead bullets (16-17 century), around 4-5mm in D, while with the V2 it simply does not see them at all. In fact, with V2 I pull mostly larger coins and not much of anything else. I also own 15" coil and in regards to small objects of say, I see the following unmasking pattern:

Small copper button (10mm D) in top of mineralized soil, same program, sensitivity, GB 0, IF 0, FE 0, recovery 4:
v1.5 - 11" performs better than 15" - can ID easier with with 11 with iron grunt
v1.7.5 - 15" performs better than 11" - can ID easier with 15 with iron grunt
v2.1.12 - neither of coils can see the button (FE 0 and F2 0), not even a chirp, completely blind, just iron grunt

It takes an awful lot of time to test things, I often hunt same fields, therefore my question, what fw do you use for digging everything?

 

Situation no 2. My friend owns XP Deus lite and we went hunting on 200 year small old field full of coke (VDI 1-2). Soil was excellent, GB was 1! He was pulling various buckles, coins and buttons from a significant depth, while I found only few coins and one other copper thing, he only made 3rd of field when I finished. We frequently tried to scan questionable targets with both detectors to confirm if they are worth digging. What happened next was a bitter surprise. He pulled a button from about 10" hole beside the coke. I asked him to drop this button into the hole to try to ID it again, but Equinox was completely blinded by the coke, all I could see is VDI 1 and no matter what program or setting I tried, and notching it out, different angle and speed, no chance, nothing. The only thing I did not try is to switch to single frequency. Deus had absolutely no problem seeing it. I feel I missed so much in that field. I was running fw V2 and I really want to go back there once more with the old version. Is there anything you think I could try to get past the coke? I'm going to that field again this weekend.

Just to add another oddity. I have done a FP reset on the equinox at some point and that made coke to sound very faint for a half a minute before it returned to full blinding strength.

Sorry for rather long post. Thank you

what number are you using:

  1. sensitivity
  2. recovery speed
  3. iron bias or new f2

Hi there and thanks.

The ground and area were very quiet, I ran it at sensitivity 22-24.
Over the difficult target with coke, I tried all recovery speeds from 2 to 8, but normally I use 3-4, mostly 4.
I like having iron bias set to 0 in either FE or F2, that day it was in FE=0, but I tried F2=0 too over that target, did not make any difference. All it could see is coke vdi 1, loud and clear.

nordic .. you get the G-B value in your terrain ...?, because GB = 1 for equinox is balancing for ferrite .., have you tried to apply discrimination on to 0,1,2 ...? in your tests ..?

 Equinox... the use of discrimination in difficult conditions is desirable ...,.... it is not necessary to rely on Allmetall ..   it reminds me of the iron volume setting which is in some detectors - but in this case also affects the ID...

The GB of 1 isn't right. You will get in the 30-40 range on mild soil.

That field has an unusual soil, very dark and porous, looks very fertile. Anyway, the GB grab was 1, which is also unusual. Typically soils here GB in 50-70 range. Though they say it is not necessary to GB in multi freq? I usually use field 2 mode, which has metal range extended from -9 to 2 by default, I had it set to -9 to 0 manually, but returned to 2 when testing on that difficult target. All it did is silenced the coke, but button did not show up. I have rolled back to v1.5 now and will test that field again. Can’t wait. Thanks a lot

Indeed. Did it few times on various patches, it was 0-1. Even after switching to tracking and then checking it later it was 0 or 1.

Friend’s Deus GB’ed close to 90, which is default I believe

With coke in the hole your recovery speed is too low to differentiate the target.  Note also with dirt out of the hole the target is essentially in air and that adversely affects depth.  Was the Deus angle to pick that target up under those more artificial circumstances?

After he removed it, we threw it back into the hole, I wanted to see if I could ID it so deep, I could not. Tried all recovery speeds. Deus was picking it up but not on every swing, he then switched it to Deep program and it was ID’ing it with every swing with ease. Not sure what program he used initially...

Wonder if we had a massive void under our feet that GB did not register correctly 😳

      Recently I was beach hunting with a friend (EQX 600) who detected almost exclusively in pinpoint mode and did very well.  After watching him pull several silver coins out of the black sand and cobble, I asked him to let me try to hit his next target.  Sure enough, my 800, beach 2, recovery 4, F2=0, full horseshoe, did not hit a silver dime.
      A few days later, I spent 3 hours trying his method.  Using the same settings, beach 2 hit about 90% of the targets.  The targets it missed were silver dime, wheat penny and copper bracelet.
      Does anyone know what frequency is used in pinpoint or what is different than regular modes?   I tried targets in all metal with no success.
      Thanks

      Detect-ED have released an alloy Arm Cuff for the Nox.  I very much disliked my plastic arm cuff for my Nox so I ordered a metal one from Ukraine.  It's been great and a big improvement over the plastic one, it's probably not ideal for salt water use as it will eventually rust.  Detect-ED being very much focused on water hunting as he's a water hunter himself has made an alloy version.  It's looking very solid and good quality and they have a free worldwide shipping promo going at the moment for it that ends on the 2nd of February.
      https://www.detect-ed.com/collections/detecting-accessories/products/detect-ed-alloy-arm-cuff


      You can tell it will be nice and solid on the shaft.

       
      The Detect-Ed Alloy Arm Cuff is a high-quality CNC cut aluminium part, with smooth edges all round. It is designed primarily to replace the fragile plastic arm cuffs found on many metal detectors! 
      The cuff is designed to be ergonomic as it hugs the arm rather than the sloppier fit of most modern machines. The placement is not dictated by the holes on your shaft, allowing you to bolt it in your preferred position.
      We designed the arm cuff without padding so that it's compatible with submerged and wet environments. However, the low profile button heads are essentially unnoticeable on your forearm and product testers have confirmed this. It also has rounded edges for comfort

      The arm strap points are lower than some standard cuffs meaning your arm is strapped down snugly in place rather than bouncing off the walls of the cuff.
      This product comes with everything included to easily install it on your detector!

      Fits Most Metal Detectors:
      - Fits on 7/8" or 22mm diameter shaft.
      - Fits Minelab Equinox 600 & 800, Excalibur & Gold Monster
      - Fits most Whites Detectors
      - Fits most Garrett Detectors (AT Pro, Gold, Max and Ace Series)


      What's In The Box?
      - Anodized Aluminium Arm Cup and Stand
      - 2 x Aluminium Tube Clamp sets
      - 4 x 316 Marine Grade Low-Profile Stainless Bolts
      - 4 x 316 Marine Grade Nyloc Nuts
      - 1 x Webbed Velcro Arm Strap
      - 1 x Hex Key Tool
      - 1 x Spanner Tool

      A decent video comparing targets on the Vanquish Vs the Equinox.
      The Vanquish really looks like the perfect first detector for someone, easy to use, built based on the Equinox so performance is pretty damn impressive.

      I figured I should post this here as I posted the information elsewhere on the forum that's less relevant than here.
      Our extremely innovative Russian friends have managed to make a range of aftermarket coils for the Equinox, they remove the security chip out of your coil, reseal your coil and give you an adapter which then allows you to run aftermarket coils.  They make a range of sizes too.   My pick of the bunch would be the 9.5x5.5!

      That's the range of sizes and pricing in Russian currency.
      You can find out more about it here on these Russian forums, you'll have to use Google translate or something similar to read it.

      And videos from them about the coils
      and lucky last 🙂
      When nobody can do it, the Russians do and they do it well.

      Hi everyone,
      I want make me sure if my program on my Detector is properly set or..
      I own Equinox for 4 weeks and walked lot of km with it (90% of time on field). But I am still little confused about my settings to forest. I tryied with settings: field 1, 5 tone, disc -9 to 0, Rs 4 and iron bias 2. Our woods is pretty clear, so I can get more depth. (I am coin hunter)
      What I read or what I heard is that park 2 is more to depth than field 1..
      But park 2 is more for dirty locations..
      I'm from central Europe and local old silver coins are differently conductive because of their age and and size.
      what would you recommend? Park or field settings?
      I'm still trying to understand it and I'm still learning. I will be glad for your advice, I have not read anything about the forest anywhere in the topic.
      PS: sorry for my english I'm not native speaker 
       
      Thank you

      Which do you think will hit deeper on wet sand?  I'd prefer a TDIBH over a DF but I'm budget limited.
