Testing The 18" Detech Mono Coil


Recommended Posts

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

Thats a fair old hunk of copper and plastic to lug around,never weighed my 20'' Sierra Grande Mono but it must be the same weight or possibly heavier,so can only lug it around with a full harness.

Thats a nice Long Cross penny,well done !!

That is a pretty heavy coil but I guess with the size of it, it's huge 🙂   I wonder what the closed design version weighs.

Good find on that coin, the coins older than the first settlers in my country 🙂

Was that the Thames you were hunting?  Fishing lures..... people eat fish out of that River??? :blink:

Nope you can't hunt the Thames with a PI or you won't move 1 cm too many nails and iron bits.I was on the Kent coast.

At the moment i am training myself machine ,digging big holes etc............then i will start to investigate other beaches

Well i may need to build another carbon shaft ,i ordered few bits to make another bungee system

Just ordered another full harness and will be using it with my Hipstick that will take the weight of almost any detector/coil combination how ever heavy they are.

That is a heavy coil, did you try running the shaft shorter so the coil is closer to your feet? I did that with my 3lb nel and found it easier to swing rather than a harness. Harness I got was awkward and hurt my neck.

Beaches here are difficult to dig more than 14" or so because they fill in so fast, really need a monster scoop to get the find in one or 2 shots. I recently snagged a 10x14 and find it does better than I thought in nail infested river bank. Taking me some getting used to for pin pointing. I have been using the nose of the coil to find the edge of the target then approach at an angle then dig from there. Is there a better way to pinpoint with a mono?

Lastly I stuffed a couple rare earth magnets from some old hard drives in the bottom of the scoop I have and seem to snag those nails pretty easy.

Hi Kac i am still experimenting,needless to.say i got to put more hours.in that coil.I bought a longer shaft last night (carbon fiber) and will diy shortly.I had same neck issue on Tuesday so.i thought i.need to work on something ,or get the coil closer or get a longer sgaft and more bungees.

Now on the sand scoop side of things after talking with Le Jag and digging myself 100s.of holes i believe 99% of the scoops arent designed for deep digging.Either you are stuck ,as the scoop doesnt have enough holes ,or you are digging too far in diagonal from the target creating huge craters .The solution may be changing the angle of the scoops and making them stronger so u can jump on it to help it to sink pull on the beast and retrieve the target.

I have an RTG scoop with the wire basket that is on the short side. Wasn't a big deal when I used a VLF as I wasn't going that deep but the PI is a different story. I could be going at too much of an angle which doesn't help as the angle of the scoop is almost 90° to the shaft.

      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!

      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??

      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)

      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?
