Detech 15" Ultimate DD In Southwest US ?


Recommended Posts

Has anybody tried the Detech 15" DD Ultimate in the SW US like Gold Basin, Quartzite or Nevada?

I recently purchased one because I didn't have a DD coil and wanted to have one in the coil arsenal. I've used it a couple of times in Central Arizona just to give it a test run and I am impressed with it's sensitivity and depth on small targets...that's all there is here...haven't got it over any large/deep targets yet. Neenad Lonic has done a few videos featuring this coil with very positive results (great videos, as usual, from Neenad). I haven't heard anything from anybody, though, using this coil here in the desert southwest. Not many use DDs with their GPXs I realize, but this DD seems to be a leap forward in DD technology. How about it? Anybody used one here in the SW? Thanks!

Talked with a customer yesterday who ordered a Detech 8in DD for Gold Basin, he has been using the 15in Ultimate Spiral DD GPX coil and has been ( killing it ), his words, on nuggets and meteorites. Said he follows after others and picks up missed gold.

The other reason is that Gold Basin and many spots in Quartzsite are among the most mild soils in the US, relatively low EMI, so there aren't a lot of people who pack the DD along to those places these days.

There are some specific spots in Q that the coil might come in handy, and those blowouts you find in the area with all the magnetite bombs. But at Gold Basin I'm not sure I see any reason to run a DD, even that Detech one. DD's get worse results on low iron chondrites from my experience (like the GB one), I'd definitely be testing it out compared to a mono before spending a lot of time in the field there anyways wondering if you missed something. But you can run small monos out there full bore, larger ones like 16" are even better so I don't see a compelling reason to run a DD there.

Just got a nice letter from a client in N Queensland who has been visiting his old patches with the Detech 15in Ultimate DD coil on his GPX 5000. He has pounded these spots with the newest other brands but says that the Detech coil has worked in ground where the others struggled. Some nice gold, 2oz nugget was down 20 inches.

I am to curious about this coil. I use a 14" elite mono and have great luck,punches deep, excellent on small gold...... really happy with it. I do need a big, best depth coil just to check all my spots. I was researching the nugget finder 25" mono and seen a video on the detech 15" coil out punching the 25. kinda thru me a curv ball, I was set on the 25 but if I can do the same with a smaller coil then ill get that. I'm just waiting on more info

I have found gold with this coil and was surprised by it's sensitivity for being a large DD. I couldn't speak to it's depth capabilities though as the ground I have hunted with it isn't that deep. I got it for very mineralised ground. The only draw back is it's weight. I have the 8"  version too and absolutely love it. Super sensitive. Excellent DD coils.

      I have been lobbying for over 6 years - more like a decade - for somebody to produce a replacement for either the White's Bigfoot, or Tesoro Cleansweep coils. These narrow 18" long coils are superb at scanning large areas for relatively shallow targets, making them excellent for jewelry detecting in large fields, and for vacuuming up recent coin drops. They are so efficient at this that some planted coin hunts prohibit them as an unfair advantage. Also great for beach detecting recent drops, relic/coin hunting huge fields, patch hunting for gold nuggets, even meteorites. See my long thread here for details on the subject.
      The short story is that the Bigfoot was a 3" x 18" figure 8 wound coil, specific to some White's models. This design has advantages, but is very hard to make, pretty much a hand made coil. And to really work best, a detector needs to be optimized for it (see additional post below). Barring some process breakthrough, I expected getting this coil back into production to be difficult at best. I therefore also concentrated on the Tesoro Cleansweep design as an option, as it is simply an elongated DD coil, much easier to produce properly in volume at lower cost, and with no oddball operating characteristics.
      I tried to get Nokta/Makro in particular to make these, as they are generally open to new ideas, and I thought, and still think, a detector sold with this coil as stock would be a unique offering that would attract attention. That came to naught, unfortunately. Then, about a year ago Detech contacted me on another subject. I used that opportunity to once again bring up the elongated coils as an ignored market, and they seemed enthusiastic about pursuing it. But then nothing, silence for a long time. I pretty much gave up hope. I was contacted by another old detectorist on the subject recently, and said just that. I had lost the original contact info from Detech, and was resigned to these coils never happening again. And frankly, I have one, so I'm covered. I just wanted so much for others to be able to get their hands on these coils, especially for machines that never had them as an option.
      Well, miracles happen!! I just was notified that Detech is producing a 4" x 18" DD coil that will be available soon (not sure how soon, but they may chime in on this thread hopefully). I do not know the weight or price, but with Detech I am sure that the price will be reasonable. The best part is that it will be for more than one brand of detector. The list I was just provided with:
      - FISHER'S F75
      - WHITES' DFX / MXT / M6
      And so without further ado, let me give you your first look at a genuinely new product for some detectors, the Detech Arrow! One of my favorite all-time coils is the Detech Ultimate series, so I know they make some great coils. This is a niche coil, but one many people crave. I want to give a very personal thanks to Detech for doing this, as it is something I have tried hard for a long time to get somebody to do, and they have granted this old guys wish finally. Thank you!

      Hi. I'm looking for a smaller than the 6x10 DD coil for my White's detectors. Would like to hear how the 7" Ultimate performs depthwise and how target separation is.

      Hey all,
         I was just wondering if anyone else know's anything about these 3 detectors! The flyers where in my new coil boxes! 👍👍

      I am looking at getting an after market coil for the MXT. Has anyone tried one of the Ultimate or SEF coils by Detech on their unit and if so which model and size did you get and how much of an improvement was it compared to the stock coil??

      After a busy week, doing an effort between heavy rain interruptions, I finally finished this work!
      Thanks for all people involved in this project for their knowledge shared...
      Underwater test next week(I hope)

      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
