  1. Good New Year Morning, Reading the “Miracles do Happen” thread about the new Detech Arrow coil (and every other mention of the coil now too) opens the mind to the possibilities of such a thing. It could be a lovely addition to scan large areas quickly to narrow focus for more intensive work, a nice back up, or perhaps a rewarding niche detector in it’s own right. Sounds fun, and a good mental exercise while waiting for spring. Having never chosen a coil before the detector that runs it, some questions come to mind. Like, which one? There is a fairly good range of detectors that it could be put on, with corresponding strengths and weaknesses of each, but very few of which I have any personal experience with. A good many of the choices are no longer made, but remain in the used market at very attractive prices. Some of those choices were once considered excellent top tier detectors that are still as good as they ever were. From what the Arrow could go on, the choices I narrowed it down to are the venerable E-Trac, the G2, the T2, Gold Bug Pro, and the Simplex. Pluses and Minuses to each of course, but my primary interest is recent drops which will be in or on the upper soil profile. Any of these would work certainly, but what I am looking for is the best TID for that top 3” of ground. Depth does not matter, but good consistent ID and being able to shut off iron audio is important. The idea is to be able to do a quick surface scan to see what is there and locate small hot spots in large sites. From the choices listed, the E-Trac and Gold Bug Pro probably have the best target ID as far as I can tell, but at such shallow depth any might work. I have no experience with any of these detectors, your thoughts would be most appreciated.
  2. I am happy to report for Garrett Axiom users and potential buyers you will have a range of aftermarket coils available for it from Detech Detech Ltd have said they are very interested in making coils for the Axiom and are currently preparing to make a range of coils for it. The excellent news is also they are planning on making DD coils, Anti Interference Coils, Spiral coils, and very likely Concentric coils. They will offer open and closed designs. Their aim with their range of coils is to make them very deep, sensitive and at the same time keeping them very light in weight. They are going to follow this thread, so if anyone has any suggestions for the size or type coil they want or think should be produced by all means report here so they can see which would be the most popular types of coils for it. I personally would like something like a 6" or 8" Mono, an 11" Anti Interference coil, a 11x6" Mono (spiral if possible) and a 11x6" DD, a 15" spiral mono, a 15" Concentric, I could go on forever as once there are options there are so many good coils you could have. This is outstanding news for Axiom owners, and is really going to push the Axiom to the next level. For those of us that have used Detech coils before you'll know how good their coils can be. A little background on Detech Ltd the company. Detech design and manufacturing advanced hobby metal detectors, treasure detectors, and deep seeking search coils. In 2001 the company designs the first PI detector in the world with microprocessor control, touchpads, and graphical image of the signal. The SSP series find wide markets and huge sales, and the funds received to allow the opening of a new branch of the company – the production of accessory coils for the leading brands of metal detectors. Detech Ltd is the first company in the world, applying search coil with built-in magnetic sensors in the middle sector. This allows perfect discrimination of the ferrous objects by the PI detectors. Trying to escape the stereotype of the round coils in 2006 the company releases a new, revolutionary type of coil on the market – S.E.F. (Symmetrical Electromagnetic Field) coils, known also as Butterfly coils. These search coils combine the advantages of both DD and Concentric coils: All Detech coils are made using high-quality materials. The housings are made of UV protected material. Their inner side is covered with chopped-strand material for better shock resistance. We use resins, which are “transparent” for the electromagnetic waves, and perfect shielding. The coils are water-resistant and operate in a wide temperature range. The search coils come standard equipped with an excellently fitting cover and have two years full warranty.
  3. I was just notified of a new coil for Simplex - 15" Ultimate from Detech. The Ultimates are great coils, high performance to weight ratio, so good news in my opinion.
  4. Really like this coil on the Simplex. Been keeping me away from my Equinox. Great coverage and sensitivity to near surface finds where the Target ID is reliable on this detector.
  5. 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: - MINELAB'S EXPLORER / E-TRAC / SAFARI - FISHER'S F75 - TEKNETICS T2, G2, GAMMA / OMEGA - GARRETT'S ACE AND AT PRO - 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!
  6. I am thinking of buying the detech 18 concentric coil for myself 5000 especially for relic hunting but I would like to know if this coil would also go for nugget hunting. If there is someone who is using it for that purpose, I would appreciate it if you could inform me how it performs?
  7. If so, what are your thoughts? Is it sensitive? How does it handle EMI? Does it punch deeper than the gp 18 inches, as their ad claims??
  8. I used my Detech 15 inch ultimate coil to with a gain of 8. moderate mineralization. Started getting a lot of chirping.Had to go down to gain 2. Is this normal?
  9. I would like to know if anyone has used the 18" detech spool and if it is worth the depth gained by buying it with the detech Dd spiral 15. Since I have that same spool. I leave the image of the coil.
  10. Today the weather wasn't that cold and when the rain took a break I ran "The Arrow" and the Ultimate 7" DD on the VX3. That really is a nice coil so to speak. Pinpoint is very good, the three targets in the vid are 3", 4" & 5" deep and no problem at all. Wohoo 😁😎, that will be fun to use on the beach and in the field. Very well done, Detech.👍
  11. I know somebody is making a new 18" BigFoot style coil for multiple detectors but I'm having trouble find out who. I'd like to see some reports of performance, etc. A little help please. Thanks Tom
  12. Anybody tested Detech Arrow coil? For Whites?
  13. Will open the box tonight and should be able to go outside tomorrow before the sun sets.
  14. 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.
  15. From my friend Atanas at Thrace Metal Detectors. Has them for many of the top models. Euro currency. 4x18 inches free shipping. Nice
  16. Today I was watching the web (again) to buy the Arrow for my White's. The only shop I came up with was one in Bulgaria so far. So I tried amazon but had no luck to find the Arrow for the DFX, but came up with this video... and thought it might be of some interest to some of you. https://images-na.ssl-images-amazon.com/images/I/H1VzUbJq2QS.mp4 Good Luck & Happy Hunting
  17. 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?
  18. Hey all, I was just wondering if anyone else know's anything about these 3 detectors! The flyers where in my new coil boxes! 👍👍
  19. 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?? Detech 13" DD Ultimate coil for V3i, VX3, M6, MX5, and all MXT models
  20. 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)
  21. 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 RR
  22. Detech dd coils say they can give good discrimination with Minelab PI machines, can anyone give a forum or reference discussing this fred
  23. I From morocco i have paper of treasure like this photo and i have other Place more than 30 with treasure in land i don't have detector for 1,5m to know the place treasure and make sure i have a EDS gold catcher but not working well always i find only ferrous target with Disc I need someone from morocco can work with me or someone help me for good Detector for 1,5m for Detect Gold
  24. 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! Dean
