Discriminator Or Detector?

When I say discrimination I mean accurate ID of a target.  This would mean that gold would not be masked or confused with iron stones.  It would mean that you could 'see' through can slaw that others could not.  With the new and improved multi-frequency it would be hard to fool this detector.  


Hi Mitchel ,

Give them time, this is the first generation of Equinox.

Maybe the next generation might get a little closer to the CTX's target ID info.

Maybe with that it will be closer to CTX's price too ? 😁

Either way the future of Minelab multi-frequency looks bright.

Happy swinging... I am off to the beach and its over 100 degrees farenheight today.

Let's do a little bit of thread combining here.  Over on the main forum it was said on Page 3:

Trashy mining sites hiding good gold have been waiting for a new effective multi frequency detector that excels at discrimination......

Hello NOX 800

Tonight I went back out to the beach one more time with the 11 inch and results were dismal because I've hit it and not much has changed.  I went to the SAME beach to understand that beach.  I've never done that 3 days in a row.

While working it tonight I remembered when I used my new 5000 on the beach back in 2011 and 2012.  Now that is a pure detector but I was staying out of the water.  (I'm thinking about using it again with the beach program and a Coiltek that I have.)

I know a couple of guys that use beach PIs.  I think they find a lot more than I do but they have to dig a lot but ... am I trading off too much to use a CTX or Equinox?

What more would I find if I used a beach PI?

What would I not find if I used a beach PI?

Let's just limit this to Beach only and specifically tide beaches that have been under water at high tide.

The way I think is a PI is pure detector.  (I know you can hear shapes but it basically detects metals and you dig them.)

The CTX, Explorer and Equinox is a detector with discrimination. 

The Equinox is very fast and can distinguish (discriminate if you will) between different types of metal nearby or sometimes within the same target (a sandwich coin).  I need to understand the standard sounds and screens or program the detector better to get the most out of it. 

Clive's books are going to help.

Use the CTX/Equinox first on an area that is not too polluted with iron, then use the 5000. I have great success with the GPX 5000/ Equinox combination. The Equinox finds most targets decently up to 10" on my types of beaches and the 5000 cleans up the lower depths well. When the wind or waves remove more sand, I do that same combination over again. So far, I have not seen a better combination out there. Maybe there is one, but they are not talking about it :laugh:

I have been out every night on pretty much the same beaches because I want to learn about this wave pattern.  The pattern is not the point of my posting here so I'm going to make a point about a couple of things I've found.

A couple of nights ago I got a solid 10 and that usually indicates something different.  As it turns out it was.  It is a stainless steel man's ring.  I've found gold rings at 10 also.  Of course I'm going to dig it just like I do the 13s which are just about always nickels.

Fringe detection on the 800 is probably what I had been referring to when I spoke of 'lack of discrimination' in my first post.  When I get a deep detection on the 11 or the 15 often times it doesn't have a good ID.  I've found that multiple targets can be unidentified at depth but also chains and other jewelry.  Corroded pennies can be from 12 to 22 in my most recent experience.

I'm not swinging anything else right now so when it doubt, dig it out.

Hi Mitchel, I agree with dig (almost), everything especially when the signal is unusual. I have found many interesting things by digging a signal that was out-of-normal. Continued good luck, let's see what the storm(s), brings.

Heres my thoughts.   Most VLFs will find about the same thing IN the salt water.........but the Nox does seem to find smaller gold.   Its a little iffy on gold on edge compared to the CTX..... and frankly you cant beat the info the CTX smartscreen gives.   But man its like swinging a dead horse over the Nox with any water movement.     Now for the PI......ALL the disc targets are still going to be there along with everything beyond the VLF depth.   Yes you can clean it out some with the VLF ......but same targets are going to be dug in the long run the way you want hunt it.    No matter how you slice that pie..... the same amount of time would be spend if you just used the PI.   Having a PI at least gives you an option many dont have..... and its possible to turn up the delay to cut back on the trash to treasure.  Hunting in AM with say the CTX would give you some indication as to the trash there.

      Unboxed it, assembled it and went to power it up...and nothing.  Hooked it up to the charger and the charging light stays solid and doesn't blink.  Able to power it up while on charge and the battery indicator reads full...but as soon as I unplug the charger, it dies.  
      Need some help please.

      Hey everyone...
      I've had my Nox for approx 10 months now and have approx 200 hours on it. 
      I'm getting more comfortable with its various modes and have fallen into a good groove with the machine. I've done well with it in great finds. 
      The area that I'm weak on is single frequencies because I have not given them a chance to prove whether it is even worth it to hunt in those modes.
      My questions are... When do you use 5kz or 10kz? Trashy or moderate trash sites? Do you use single just to cross reference a signal against multi frequency?
      Has anyone dug anything significantly better in single vs multi? Has anyone been impressed at what single frequency can do vs multi? 
      Note: For the most part I hunt trashy sites with relic/jewelry/coin mix. At the parks I simply put it on Park 1 or 2 and do not think about single frequency. But when in lot sites, and I'm running into lots of trash, I wonder how the single frequencies will work for me. Or better yet... what should it be doing for me that's better than multi?
      Any feedback is appreciated.

      Here are my best finds from my last two trips with my new Equinox 800.  The site is an old plantation that has been under continual cultivation since the 1830's.   All detecting took place in plowed fields with over 180 years of accumulated nails, iron farm implements, and assorted trash.  Running the 800 with no discrimination sounds like machine gun fire due to the massive amounts of nails and other iron (I wasn't searching this way though!).  I was running the 800 mostly in Field 1 and occasionally in Field 2.  Field 1 was a touch quieter. 
      I found 6 Tax Tokens, a V nickel, a buff, and one Jefferson nickel; 5 pennies including one IH;  one merc and one 1876 Carson City seated liberty dime.  I was very excited about the CC dime since this is a Mississippi site and I have never found one before.  Unfortunately both dimes have plow marks.  This is not uncommon considering the amount of cultivation.
      Additional finds included a nice flat button, bridle boss, several brass rivets, heel plate, and other whatzits.  The smaller rivet was fairly deep.
      Considering the amount of trash I was very impressed with the 800.

      I read this in another forum and thought it was interesting. I asked the poster for permission and he said yes.
      Mark Carter Iron bias just alters a threshold that determines if a signal will be classified as iron or not. It’s not a filter per se and doesn’t affect depth.
      The benefit of a low iron bias has been correctly explained. But that is not the whole situation. In ground that is trashy and/or heavily mineralised, especially then the nox can be chattery even when noise cancelled and ground balanced. Raising the iron bias will then cause the chatter to be classified as iron and reduce the false alerts accordingly. 
      That should be part of your routine if you want to quieten you machine. This effect happens in all metal and discrimination modes. But in all metal mode, the false will
      become an iron grunt and in disc it will be silent (assuming you have the audio set up that way). Yes, a high iron bias may lose you some masked objects. But the advantage is you won’t go crazy and you can perhaps cover more ground because you’re not having to double check false signals to see if they reoccur. 1 Manage

      If the Equinox will obsolete all single frequency detectors why does it have the option to run as a single frequency machine?
      Surely this means in this mode the Equinox will obsolete itself!!

      Dear Friends ....  Have purchased the Equinox 800 and Would like to know if anyone has had or used this coil and would like to share your thoughts on/of this coil. I realize that it has not been around all that long but perhaps some of Our Forum has had some hands on experiences with it? Any an all remarks would be appreciated.  Considering on purchasing! Thank you very much! Co
