The New Coils For The 23 And 7

Recommended Posts

Maybe something to think about. Bearing in mind I am probably going to get these new coils for the 23 and 7 myself, people should at least consider, a lot of people are saying something along the lines of "my detector is out of warranty anyway, so I`m not risking anything fitting these new coils", but, it is Minelabs policy to not repair any modified Minelab detector.    I daresay that if you were to send a out of warrenty 2300 or 7000 back to Minelab for repair and Minelab saw you were running a unsanctioned coil, they wont repair the detector.    You could end up with a 4K or 10K detector that all it`s good for is to fill it with concrete and use it as a anchor.
Like I said, I am probably going to get the coils myself, but I will be doing it with the idea that if either detector fails I will probably have to throw it away, and that`s on me and no one else.
I have no reason to suspect the coils are going to cause any damage and I wish Coiltek and davsgold nothing but success with these new coils.

It's Minelab's policy not to repair any detector under warranty for no cost to the customer if the coils damage the detector, they will however repair any detector when the customer pays for the repair, they're not evil 🙂

All they're saying is if you damage your detector using the coils the warranty will be void, not that they won't fix it at your cost.

Simon I did not at all follow what you just said but IF you have a modified GPX and you send it to minelab for repair, Minelab will not look at it

ahhh ok, yes neither are permanent modifications though, you can set the back to normal in no time and they can't tell it was done 🙂

Sorry for not making sense, busy morning

The main difference I see between fitting an aftermarket coil to either an SDC2300 or GPZ7000 is that the GPZ7000 was designed to have coils swapped, granted it is supposed to be the 14 and 19 ML coils, but the SDC2300 it is clearly stated the machine was not designed to have coils swapped.

 Even the earlier GP and GPX ML detectors, ML always stated that if aftermarket coils were used it "could" void warranty, as ML said they could not guarantee anything but their own coils on their machines.  Not many people ever worried about this. 😉    

That's my understanding anyway, and as always if the internals of any ML detector have been modified then ML have the right to send them back unserviced, if they choose.

cheers dave

How are Minelab too tell if you have a modified coil fitted ?? in the case of the SDC if anything did go wrong then just change the coil back and no one would be non the wiser if you dont tell them,also from what i can see the GPZ after market coil option requires the end plug too be taken off and used because of the chip problem,but as most folks who have bought a GPZ would have 2 factory coil,could they not just send back the decent non modified coil back with the detector or am i reading this wrong ??

Of course Minelab will post a 'warranty warning' its natural as they dont want lost sales of its products,but the Coiltek afrermarket coil option looks a superb product,but Minelab would only have knowledge of you using this aftermarket coil product if you told them about using it.

Over the weekend I saw someone take a new 2300 and place on one of the new coils.  After using that coil for a bit of time he switched back in about 15 minutes.  The new coil found a tiny little nugget.  I don't remember which one of the 3 he used but he ended up buying a second coil by the end of the weekend.

My first detector was a modified Excalibur 1000 from Excalibur Dave and I got really ripped off.  Only one headphone would work and the pods would be staticy when adjusted.  It was a Frankenstein of a machine and was heavily abused.  I was new and bought on a recommendation plus thinking i needed modded gear.  How wrong.  Even though he said he would stand by his work for a year, he didn’t, and left me high and dry.  I called Minelab, told them what i had and they were more than willing to help me.  When it got to the repair center the headphones were garbage and replaced, pods and board, replaced, the case had a crack (no longer waterproof), replaced, and a couple other things.  They basically brought that Excal back from the dead, I had to pay, it wasn’t free but now My Excal is what it should have been from the start, and its still my go to underwater detector for the last 4 years.  That was a huge lesson learned.

As I recall, he was using the 11-inch round when he found his first nugget, and dug 2 more with the 5x10-inch elliptical.

I`ve been told the 10x5 is a killer coil on the small stuff.   It`s probably the one I`ll get.

      So just spoke to the guy I get my minelab threw and aparently the new russian could that people are getting great results with on the gpz ane bow in process of testing some for the gpx so will be interesting to see how they go

      I have had a Garrett ACE 250 for several years and just bought a very slightly used Garrett AT Pro a week ago.  A couple of times I did not get any sound when first turned on but after wiggling the coil cable it started giving tones again.  On occasion it has suddenly started chattering with almost no movement and I have done a reset and it corrected the problem.  My main issue right now is that if I bump the coil cable close to the connector I get a tone every time.  I have removed and re-inserted the connector twice making sure it is fully inserted but still get the tones.  I have made sure its not the connector itself.  I don't have another coil for the AT Pro to swap out.  I texted the previous owner to find out when he purchased it hoping it was less than the 24 month warranty that Garrett has.  Wondering how strict Garrett is on fixing issues like this or replacing a coil with a bad cable if I was not the original purchaser.  Any suggestions are appreciated.

      This is not about detector versus detector. It is just a video questioning if small coils are always better in trash, and whether concentrics are always better than DD coils at handling ferrous targets. Too bad about the wind noise. Good stuff though illustrating there are no magic answers.
       
      For detailed information see this article VLF Concentric Vs DD Coils
    • By Steve Herschbach
      VLF detectors can come with DD or concentric coils. This is similar to but not quite the same thing as DD versus mono on a pulse induction detector. There are three basic coil types in wide use, Concentric, Double D (DD) and Mono. A VLY detector transmits and receives simultaneously and so there must be both a transmit coil and a receive coil. A pulse induction (PI) detector can alternate between transmit and receive and so one coil can be employed as both transmit and receive in an alternating fashion. There is confusion on this but simply put VLF (induction balance or continuous wave) detectors do not employ mono coils. A VLF can only employ the concentric or DD options. A pulse induction coil can  work with all three types.

      Metal detector coil types illustrated - concentric vs DD vs mono
      VLF detectors are more alike than different these days. One thing that can make a real difference is what coil the detector comes with. Two very similar models will be quite different if one comes with a 12" round concentric, and another an 11" x 7" DD.
      In this case the very same detector can be turned into two different detectors by changing coils. Here are a couple rarely seen on the F75 - the 10" x 5" DD and 10" elliptical concentric. A big difference between the Teknetics T2 and Fisher F75 was that the F75 came later and the ability to use concentric coils was added. The T2 can only use DD coils.
      Why DD or concentric? DD coils are all the rage these days. However, concentrics have more consistent detection patterns with less dead spots up close. Every notice how that DD coil goes wacky on shallow targets? And concentric coils are much better at identifying flat ferrous targets like bottle caps. Here it is from the guy that should know best, Dave Johnson, lead designer on the F75.
      About Search Coils by Dave Johnson
      Search Coil Field Shape by Dave Johnson
      Coil Basics by Carl Moreland
      I like the 10" DD for the solid design, better for working in stubble or other locations where an open coil might hang up. The concentric just for being better behaved. The DD is the better prospecting coil for bad ground. Concentrics do well on milder ground.
      A note on coils. The blade like knife edged detecting pattern depicted in DD marketing ads is largely myth. Electromagnetic fields radiate and simple coils cannot focus them into beams. A round concentric coil has a search field shaped like a soccer ball cut in half. A similar size DD coil will have a search field more like a football cut in half lengthwise. If you ever doubt this, just fire up your detector with a DD coil, flip it over, and run a coin under the coil noting where the signal fades at different locations under the coil.
      Finally, depth is more related to coil width than coil length. Think of a 5" x 10" coil as a stretched out 5" coil, not as a skinny 10" coil. That is why when listing elliptical coil sizes you will often see me putting the small number first. Marketers do it the other way around so you tend to think you are getting more than you are.

      Dilek has mentioned this on some of the forums that a new coil offering for Impact much like what is given on Anfibio package.  Looks like the coil is indeed loaded to Nokta’s site now.

      There are a couple lots on Ebay where the seller includes a Tesoro Widescan (DD) 5 3/4 inch coil with plug modified/replaced to operate on a Fisher Gold Bug (the new generation Gold Bug, not the 1990's versions).  I'm wondering if anyone here has heard about the possibility of going the other direction -- putting a Fisher Gold Bug / F19 / Tek G2,G2+, Tek Greek series coil on a Tesoro?
