Hey Guys,

   Here is what I can tell you, as I have had all the coils now for 3 days.  I'm hoping some of my customers will get some reports out on my forum and here by the end of this weekend.   The conversion is really easy, but once you convert you really can't fold up your detector like you can with the stock 8" coil.  I think for the most part, customers that are buying these new coils are looking for more depth and coverage and a bit more sensitivity and easier pinpointing with the 10x5".  

The 10x5 is very easy to pinpoint with and seems just as much, but probably a tad more sensitivity to small gold vs. stock 8".
The 11" Round is getting more depth overall on at least 1/2 Gram and larger from quick testing in the field.  
The 14x9 Elliptical is also getting more depth for sure, best gains on larger gold (2+ Grams) at depth and more overall coverage per swing. 

From what I have sold, it's about equal on all the coils, not really all larger or smaller coils.  I have been testing the 11" Round for some time and it does get more depth than the stock 8" searchcoil.  The 11" is a bit heavier along with the 14x9 if you arm is conditioned on the 8" stock coil.  

I'm positive if you own a SDC 2300 you will get benefits from one of these new Gold Extreme Coiltek coils.

Anybody have any real field reports (or tests) on the Coiltek 11" ROUND coil?
I am looking to find out how much deeper it is over the stock 8" SDC coil.

So far, I have seen one Youtube video that was inconclusive.
Seems like it increases depth by a slight amount but decreases sensitivity to the super tiny bits...1 grain or less.

Even an extra 1 inch depth on those prickly specimen nuggets, it would be worth buying for me.
(Unless I can get one of those new 10x9" or 12" Round X-Coils for the GPZ.)

Thanks,
Don

Hey Don,

   I have been testing the 11" Round and it gets more depth.  Just from quick testing on 1/2 gram and better, it's getting that inch.   The 3" larger 11" Round over the stock 8" SDC coil does give you more depth, and then even more with the 14x9 (which is about a 11.5 to 12" round equivalent). 

The general rule of thumb on all coils is when you increase the diameter of the coil, you will gain in overall coverage and depth on larger gold.  This means at some point you will loose some sensitivity to tiny gold in hopes of finding something a bit larger at a greater depth.  For the most part, electronic prospectors that go with larger coils are not looking for tiny 1,2,3 grainers anymore, but in hopes of Gram or Pennyweight plus pieces at greater depth. 

Hope this helps a bit,

I went out today for the first time with the 11" round. My area still had too much snow to do much detecting but I was able to do some tests against the stock coil, the new 11" coil and my Gold Bug with the 10" elliptical .  I tested nuggets of .25g, .5g, 1g. 1.5g and some assorted larger specimens with between 4g and 35g of gold content.  The 11" will pick up the .25 at nearly the same depth as the stock 8" but the signal is much more subtle.  On the .5g they the 11" has a bit more depth, maybe about an inch but again the signal is much more subtle. On the 1g and 1.5g the 11" gets easily 1"-2" more depth. With the larger specimens the 11" gets dramatically more depth. On the 35g sample I was able to get a solid repeatable signal at at least 6"-8" deeper than the stock coil.  The only piece where the 11" performed worse was on a specimen with about 7 grams of gold in quartz with a total weight of around 40 grams. There is a lot of gold but it is very fine. The Gold bug hits hard on it up to about 8"-10". The stock sdc will get it at 6"-8" but very faint. The 11" doesn't get a solid signal over 3"-4". A couple of final observations is that the large pieces when at depth give a solid signal on the 11" but it is reversed . As you get closer it changes to a normal signal. Lastly overall all it seems like signals on the 11" are less obvious than the stock coil even at shallow depth. With the stock coil a .5g at 4"-5" screams. The 11" on the same nugget gives a clear signal but nowhere near as obvious.

Thanks for the post! My dealer told me the same thing as in this Minelab statement when the coils first hit the market, it sounded like they encouraged him not to sell them.

This statement from their product notice clearly sets out their point of view

The SDC 2300 is not designed for changing coils nor for use with other coil sizes and specifically any damage which is assessed by Minelab or its Authorised Service Centres (ASCs) as having resulted from such modification will not be covered by the Minelab warranty.

I wonder how much damage this has done with the Minelab/Coiltek relationship.  Although I think that died some time ago, they were never allowed to do GPZ coils, or other detectors like the Equinox.  Minelab went to extreme lengths to prevent them making GPZ coils by putting that encrypted protection chip in the upper end of the coil cable.

My point of view on this is if you stop 3rd party manufacturers at least provide your own in house coil solutions, the GPZ being such an expensive detector with only two coil options is just unfair on the customers, especially after the massive range of coils on the GPX series.  No wonder the Russians have come to the party making aftermarket coils for the GPZ bypassing the chip protection by using the chip and a bit of a haircut of the coil cable 🙂

The Equinox being a small fraction of the price of the GPZ already has more coils and hopefully more are coming like a small elliptical.

As a guy that was the service manager in a computer manufacturer and service center, I fully respect Minelabs position on this, we used to put warranty void if removed stickers on everything trying to stop people messing around as it caused us a nightmare, legally they weren't binding but it stops some people screwing up their equipment.

Yeah, ML have been top detector manufacturers but when it comes to coils,,,,,,,,,,,,,,,,,,,, from the SD`s garbage lid through to the insulation coil wiring that couldn`t handle UV etc etc, I believe they should maintain their R & D speciality developing detectors, let the aftermarket fellows who have demonstrated for many years they have the go when it comes to coils, let them do what ML can`t. A marriage of a sort that has and is working to us the users advantage. 

I guess it depends on each users need for warranty, with detectors this means little to me, in my 40 plus years use I`ve sent one detector back with a fault, plus a couple of coils, I know of no other piece of tech or machinery that has given anywhere near the return todays gold detectors give in return for dollar. Then if I take into consideration the joy and satisfaction that comes from this great hobby, I can only say ML keep doing what you no doubt do best and let the aftermarket coil manufactures continue to supply us with coils. 

But I suspect ML are well aware of this and they have no choice but issue their position by distancing themselves because nothing can be made totally idiot proof.

      I would like to start a thread of peoples opinions on what they found between these two machines with various coils.  I love my SDC and have found my biggest and smallest gold with it (8”).  My GPZ has definitely gone deeper for gold (14”).  I am about even on the total count for each, weight a being different story.
      I understand that if you only have one detector then you want coil options, but if you got both I wonder what would be a better bang for your buck?  A 10” Xcoil at $1000 or a 11”Coiltek at $310.  Thats if they compare at depth and sensitivity.
      Norvic I would love for you to state your opinions here, you seem to have the most on thses just based on other posts.

      I’m in the market for a new coil for my GPX 5k since the others have seen better days etc. 
      I’ve seen some good reviews regarding the coiltek elite series and had a couple of questions regarding them. 
      I detect in the sierras with pretty mild ground for the most part. The gold ranges in size but, generally under 5 grams and pretty rough/prickly. I know the 5k doesn’t handle that kind of gold as well as say the Zed, but my buddy has one of those. 
      My big question is whether to go with the 14” mono or the 17-11” elliptical. Any advice here would be appreciated as I hope to make this the go to main coil. 
      And if there is another coil I should be considering as well please share your opinion. 
      Thanks!

      My Order of Coils for the SDC-2300 landed.  I'll be shipping Friday and Saturday.  Let me know which ones you want and be sure to get a Hardware Kit too.
      I look forward to hearing and seeing your Success. 
      Photo is one of my Field Staff and some of the SDC-2300 gold he found with the stock coil.  Just wait until he gets to swing one with the other coils.

      As most of you know, I have these new coils on Order and will be getting them in soon.
      Many of you have asked to see a video on how to Assemble and here it is.
      If you have not contacted me to get your name on the list (not collecting $$ until I have the coils), then please do so.
      A recent 4 gram was found at a reported 12".  I was and still am pretty excited to see more gres gold discoveries as folks get them and start making posts.
      Gerry's Metal Detectors in Boise, Idaho at www.gerrysdetectors to get on the list.  Or just call/email me.
