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.
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

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
