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!

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?

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??

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.

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?

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.

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.👍

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

Anybody tested Detech Arrow coil? For Whites?

Will open the box tonight and should be able to go outside tomorrow before the sun sets.

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.

From my friend Atanas at Thrace Metal Detectors. Has them for many of the top models. Euro currency. 4x18 inches free shipping. Nice

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

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.

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?

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?? Detech 13" DD Ultimate coil for V3i, VX3, M6, MX5, and all MXT models

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 RR

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

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

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

Wondering if anyone uses the Detech brand of coils on their Minelabs and how do you think they compare with coiltek and NF.

Their SEF and Ultimate coils are legendary, as are some of their gold coils, but saw that now their making coils for the Makro Racers too: The Ultimate coil might do well on the Racers if you have a need for a large coil. HH, Brian
