32" Detech Concentric Coil

Recommended Posts

Hey Guys,

   I have been carrying Detech searchcoils for years and they have really came a long way.  There has been a lot of demand for this new, giant 32" coil here in the US.  I have about a half dozen pre-orders on them already for Minelab Pulse Induction owners, mostly GPX users. 

If anyone is looking for one here in the US, I can get you one for sure.  

https://www.robsdetectors.com/detech-32-concentric-search-coil-for-minelab-gpx-gp-sd-series-gold-detectors/

$1,299.00 US with FREE Shipping/Insurance

P.S.  A friend of mine is excited to run one in Florida on some beaches he found some very nice Spanish gold coins.  There hasn't been anything this large out yet, so many beach and cache hunters will love this one beyond all the gold nugget hunters.

Yes Keith, Iron reject works with these coils. 

More good news on the ($AUD) pricing from Detech Australia:

"Great news! After many refinements in the manufacturing process which has reduced manufacturing costs, Detech are pleased to pass the cost savings directly on to their customers with a greatly reduced retail customer price for the new 18” concentric coil, to suit Minelab SD GP GPX machines

This 18” coil will pleasantly surprise you with its weight of 950 grams (approx) with open Skid*

The first lot of stock coils sold and these customers will all be given a refund to coincide with the new pricing

The coil will now sell for $540

Great opportunity for prospectors to experience the benefits of the concentric

Next shipment should be here next week

*A closed skid will also be available for this coil and it fits very snugly"

 

 

I should add that I still haven't been able to put much time in with the 18" Detech CC, but impressed so far -

Wonder if these coils would work on a TDI Pro ?? most GPX designed mono coils work on a TDI but has anyone tested that theory with this coil,not sure if the TDI sl would have the power to run this coil but the Pro version could well do,i use a Detech 18'' mono coil on my TDI and it works a treat and also a 20'' mono from Jimmy Sierra so it can run coils uptp 20''.

Any thoughts about this one ??

Concentric coils work like a Double D coil, one RX and one TX winding, and not like a Mono that has only one winding, If your TDI can run a GPX DD then it may work.

Just got mine last week, but have not had a chance to test in the field yet. Air tests were impressive to say the least on GPX, but not good at all on QED. Will take the coil to Howard to see if he can work out why this is so, as the DD coils work well on QED since his last upgrade.

I'm pleased to see this has been resolved already.  It seems it was only a problem on some older model QED's and a simple fix in the end.  I look forward to hearing how your CC coil goes on the QED.

Interesting report PT. Pretty much in line with what I've noticed with CC coils as well, particularly the ground penetrating ability and minimal EMI.

I still haven't had time to get away and have a proper play either, but this adaptable coil holds intriguing possibilities.

      Hello to all 2 weeks a go i took the plunge and bought the most suitable coil for my needs......its heavier than my other coil but the aim was :
      How deep can i really dig
      And how much ground can i cover
      So i mounted the beast on my carbon shaft after a few rubber washer adjustment i was all set.Tide was good weather was clear but it s dark after 5pm and the beach has mudflats and alone with limited network i won't take risk of getting stranded.Anyway it heavier and after a few adjustment with the SAT ,the gain  and the delay i was all set.
      This coil is blasting targets really hard i pick up the knife at 50cm and dug a real crater ,not many targets except the silver earing and the find of the day a Silver Long cross penny circa ad 1272-1303 nothing really amazing but i could not  find anything old about this area...........
      Next day went back to try the CTX on the right side on the spot and i pick up lots of fishing weights.
      Can wait to try the coil again maybe next Monday

      Been reading a lot about the new Coiltek, Nugget Finder & now Detech coils of late. I haven't had much to do with any of these but have detected a small area immediately after 2 x GPX4500 with the Coiltek Elite 14" mono attached. Although not an exhaustive or scientific test the end result was I got 8 x subgram nuggets from the area with the SDC & the 4500's nothing. 2 of the subgrammers came from adjacent to their scrapings so they knew something was there but was still iffy enough to walk away from. I keep hearing or reading how these coils are transforming GPX's into SDC's or even GPZ's but this short "test", for want of a better word, put some doubts in my mind.
      I've got no doubt that there is improvement in the new coils in how they enhance the target information or audio response of the detector through better windings etc. but I'm not entirely convinced it's as substantial as some make out. My thoughts are it may be about 10% performance improvement  (every bit does help regardless) & 90% of a placebo effect i.e. you buy a new coil excited by the possibilities of it's performance, you regain some enthusiasm & become more positive in approach even detecting more carefully + with more purpose - then when you find gold of course it's the new coil that done it right? 
      Another thing that has me scratching my head is how excited people are about them finding very small gold. My smallest bit with a GPX5000, fine gold & standard 11" Minelab Commander mono coil was 0.03 of gram (I think about 0.46 of a grain) so they have always been capable of doing it even with an unfashionable coil (but still a good one).
      Like I said I'm not doubting that there are definite performance improvements, much like the introduction of litz wire, but I do believe a lot can also be attributed to a refreshed or reinvigorated enthusiasm too. 
      New detectors could also have a very similar affect on us. What do the experts reckon?

      Hi all,
      I've done up a video comparing some of the new coils.
      I'm an agent for Detech coils, but tried to be as unbiased as possible.
      Be interesting to hear your thoughts on the results.

      Detech has introduced two new coils for the Minelab GPX, GP, SD series of Gold Detectors. They are listing them as "New Technology".
      They are currently being tested in the Australian Outback.  I will have pricing, availability and more information as I get it from Detech.
       
      Please pm me if interested.
       
      Thanks,

      Is $67 USD a good price for a Detech 15x8" GPX Coil brand new, still in box from a reputable seller?  I thought it was so I bought it.  It had the feature I love about my 12x6" X-coil. good ground coverage with sensitivity to small gold.  It's why my X-coil has barely left my GPX since getting it but I'd prefer to have a coil I can leave on each detector, saves me time and effort in changing coils too often
      I believe this is an old style bundle wound coil....
      Has anyone had experience with this coil?
      I ended up buying it today as the price just seemed too good to refuse and hope to use it on my QED.
      I can't find out much about it, only one person I know has had one and wasn't overly impressed but I do know coils behave differently in different environments. The manufacturers promo text makes it sound good.

       
      15 x 8" Monoloop Closed Design Elliptical  800g
      For Minelab GPX, GP and SD series detectors
      This closed design coil has been designed to go deeper than standard coils.  You can search a large area quite fast, due to the easy size and weight, without losing any depth!
      Made to locate Gold!  Very stable, no false signals, able to work in heavy mineralisation.  Add this coil to your detector and go over ground you previously searched and you will be pleased with the added GOLD you will find. 
      Every GOLD prospector's wishlist item.
      15 x 8" MONO coil is sensitive to smaller gold and still very stable over the ground locating gold nuggets not only in new undetected ground, but gold has been found in many areas that have been searched with detectors and said to have no more gold to find.  MONO type search coils and larger size SEF coils have become the coils of choice for most professional and serious gold hunters throughout the world.  Better sensitivity, more accurate, able to locate both large and small gold nuggets that other coils miss.  Closed or solid design makes searching rubble strewn ground a breeze without snagging.

      Detech dd coils say they can give good discrimination with Minelab PI machines,
      can anyone give a forum or reference discussing this
