I have been detecting an old home site. I started out with my ORX and the x35 9" coil it found alot of targets, and then kinda went quite, so i grabbed the Tarsacci, with its 12" coal and the ground let up again , and in the one spot the east yard it to went silent, but what gagged me was i was digging down 14 inchesand doing what i call a frontabout 3ft wide and just detecting the dirt i was throwing out of the hole and using a magnet to pull out the iron and going over the dirt again but now i was using the Mackro racer with the 5" coil to do this and it was pulling out lots of non iron targets this way but what caught me off gard was when i went out side of the hole and just for the heck of it started scanning the surface the other two detectors had gone over , i started getting hits, pulling up more shotgun shells and other non iron targets , so the 5" Racer coil was doing somthing the other two could not do . it was getting in between the metal and at a good 6 " , this took me back because i figured no way it would do so well but it did and is ,

I’m looking for an after market COIL SUPPORT for a COILTEK 10X5 EQUINOX coil…. I just finally bit the bullet and found one…. I’d like to put a coil support on this coil to hopefully not break the tabs too soon on it…. Does anyone know where a coil support for this coil can be obtained ? ? ?………thanks …..Al
as I already put in another post, I just bought a second-hand gpx 5000. It comes with the comander 11 DD and 11Mono coils. I would like if it is possible for a colleague to recommend a coil to complement the ones it brings. Its use would be to search for coins. I've been looking at the detech 15 inch DD ultra sensing. If anyone has used it, what can you tell me about it?
I am 80 and having problems trying to figure out the difference between COR'S coils and Nel coils.Looking at a 9.5" x 5" d.d. coil for my F-70,seems the Nel coils are harder to find ,but the Cor's are easy to find.Rumor says two brothers own both coils companies is this right?🙂
After reading all items available I am confused. It's probably just me so I apologize if this is a dumb question. In soil that has low mineralization which coil will go deeper and is more suitable, a DD coil or a mono coil of equal size? Or in low mineralization does it not matter if you use a DD or a mono coil?

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!
