I was wondering why I haven't seen this question anywhere. Does a bigger coil use more power?

I came into possession of a Deltech 8x6 SEF Pro coil for a EDS Winner detector. Would this coil work on a MXT Tracker E-Series detector? I believe the frequency for the EDS Winner is somewhere around 28khz. New to the sport so looking to get educated. Thanks.

I was lucky enough to have a guy on here make contact with me offering his Elliptical for sale to me. Right now my money is on the way and by the end of next week it will be in my hands . I’m excited to give it a try on two lots almost down town that has lots of history. I’ll be posting my finds right here.

https://www.minelab.com/usa/community/treasure-talk/a-crash-course-in-everything-coils While there is nothing revelatory written here, does anyone else find it interesting to see them posting this topic at this time? With all of the recent aftermarket coil discussions filling these forums for both the SDC and GPZ, it makes one wonder if they are just trying to be relevant or have a plan to change things up. It’s speculation. But, the timing is interesting. It must be uncomfortable seeing another company modify your product for a profit. There’s also probably a good reason they haven’t released alternative coil options to date. Hopefully, nothing of lower quality gets released in haste.

A piece of information I value and often can't find (or can find, but sometimes unreliably) are coil weights. I'm attaching a list I've assembled. These weights include the cable and the coil cover (unless noted). The uncertainty of the measurements is estimated at about 2 grams. Coils that are made with the same name and nominal dimensions, but for different detectors, will likely have some difference in weight due to the number of windings and possibly other discrete components (e.g. resistors) inside. But you can still get an idea of a weight if you find a coil you're interested in but it's listed for a different detector. An example here is the Detech Ultimate which came in at 532 g for the Fisher F75 and 549 g (as measured by Phrunt) for the Fisher Gold Bug. A more extreme case here is the "Digger" coil for the X-Terra series at 481 g and the same housing, cable, etc. of a prototype Gold Bug coil weight of 437 g. Coil_weights2.pdf

Rules say post to relevant information/items of interest. Fits the bill with me. I hope I'm not violating any rules by posting this it's not mine nor do I know the seller but I was browsing Metal detectors for sale and I came across this: https://orangecounty.craigslist.org/spo/d/los-alamitos-whites-metal-detector-xlt/6916021862.html I am posting this because included in it is a bigfoot coil and when I used to run a couple of Whites machines I remember folks raving about the Bigfoot coil and for what I understand the coil alone is quite pricey nowadays.

More speculation. http://golddetecting.forumotion.net/t26580-new-gpz7000-aussie-made-coil-rumour

A Minelab dealer down Geelong way put up the below post about an Aussie company starting to make GPZ coils. Interesting timing, wonder if the Russian guys have forced Minelabs hand to allow a local 3rd party to make coils. Here is the link to the facebook page https://www.facebook.com/luckystrikegold/ Not looking to start a fight here, just sharing info. I don't care what coils everyone wants to run lol Lucky Strike Gold Brand new GPZ coil coming soon! ? There is a rumour in the wind that an Australian company will soon be making GPZ 7000 coils. At present there are only Russian made after market coils being made, so hold off and bag yourself a genuine Aussie made one. They will be cheaper than the Russian coils and, as always, very well made.

Something I've been wanting to do for a while now..I got another x ray generator couple weeks ago and wanted to try it out on my DR System.. Heres most but not all of the coils I have. 1. CTX 6" 2. TDI Pro 12" double mono 3. CTX 17' 4. XP Deus 9" 5. Miner John 8x12" mono 6. x cal 8" 7. Gold Monster 6" 8. Fisher Gold Bug two 6" 9. Nox 6" 10. Nox 11" 11-14 GPZ 7000 stock coil

Clearly, with the huge amount of interest that is being shown in the after market coils for 7000, it`s obvious that there is a market out there for coils other than 14'' and 19". I don`t take the 19" out much because I have had very little success with it and with my bad wrists it`s just too damn heavy, but Minelab did tell us in the early days of marketing the 7000 that they would be releasing a 11" coil down the track, and now there is another company that nobody has ever heard of making a huge range of coils that are lighter and have so far been very well received by the public. What`s going on Minelab?

I have a Vaquero with the stock 8"x9" concentric coil. I'm wondering if I should get a DD. There are quite a few out there, for example the Tesoro 5"x10" (stock on the Lobo SuperTraq) and similar size (open structure, though) by Mars and also Cors/Nel. I'm only interested in coin hunting with this detector. Anyone out there with experience care to comment whether or not I'll see (hear!) much difference if I get one of the DD's?

I have had a Garrett ACE 250 for several years and just bought a very slightly used Garrett AT Pro a week ago. A couple of times I did not get any sound when first turned on but after wiggling the coil cable it started giving tones again. On occasion it has suddenly started chattering with almost no movement and I have done a reset and it corrected the problem. My main issue right now is that if I bump the coil cable close to the connector I get a tone every time. I have removed and re-inserted the connector twice making sure it is fully inserted but still get the tones. I have made sure its not the connector itself. I don't have another coil for the AT Pro to swap out. I texted the previous owner to find out when he purchased it hoping it was less than the 24 month warranty that Garrett has. Wondering how strict Garrett is on fixing issues like this or replacing a coil with a bad cable if I was not the original purchaser. Any suggestions are appreciated.

There are a couple lots on Ebay where the seller includes a Tesoro Widescan (DD) 5 3/4 inch coil with plug modified/replaced to operate on a Fisher Gold Bug (the new generation Gold Bug, not the 1990's versions). I'm wondering if anyone here has heard about the possibility of going the other direction -- putting a Fisher Gold Bug / F19 / Tek G2,G2+, Tek Greek series coil on a Tesoro?

Good morning, just looking for some feedback on the CoilTek 18X12 Goldstalker Mono Elliptical coil. Anyone had any experience with it? If so, what are your opinions on its abilities please. On a different note, how about the Minelab Commander 15X12 semi-ellipitical mono? I realize there are newer, probably much better coils for the GPX, but I'd really like some information on either of these coils by anyone that's used them. Any feedback on either coil is much appreciated, including which one you think might be better than the other . . . (I've never used either one, but have a chance to buy, but can't find any reviews so far except by the manufacturers.) Thanks for your time, and all the best, Lanny

Hi all, I am looking to buy an additional coil for my MK 14kHz to get some extra depth while in the field. I cannot decide between AF35 and KR40. Could you please advise which coil shall I purchase to add some depth for coin, jewellery and relic hunting and why? I would really appreciate your answer! Thank you in advance!

As introduced on the White's pulse induction detectors beginning in 2008. https://patents.google.com/patent/US7994789 Abstract A new dual field search coil for pulse induction metal detectors has multiple coplanar wire coils of different diameters connected in series with the output of a pulse source, overcoming the loss of target size resolution associated with a single coil search loop. Small objects are sensed by an internal small coil and larger objects are sensed by the larger outside coil, and the overall depth of target sensing remains similar to that of a single coil construction. The smaller coil is isolated from the pulse source by the inductance of the larger coil and will ring at a frequency determined by its own parameters. To prevent the smaller coil from ringing, a second damping resistor is connected across the terminals of the smaller coil at the junction of the large and small coils making up the modified search loop.

Has there been any talk of an eight or nine inch coil for the nox in the future?

We recieved the 15's from Crawfords in the UK . Who kindly sent mine with Randy's together for Saturday delivery .Thank you the Crawfords crew you made this hunt possible . Kev my son with his sooty and sweep went out with Randy Dee on a permission that has been well detected in the last few years . And producing Roman coins and artifacts . Randy and my self where armed with the new 15 inch coil . I was in field1, AM ,5T,BIAS 4,RECOVERY 2 . I usually set at 20 but due to the nature of the field iron infested . I settled with 17 with the 15 . It worked great . As we progressed I meet up with Randy mid morning (fund out ) Bloody hell the whyly fox had 8 romans .His comment was THIS A CRACKING COIL. Coming from Randy that a great complement as he has 40 ++ years detecting and has had the machines . I had 2 ???? I was detecting back to the car for lunch . BANG 31 hhhuuumm . Dug over the full length of my JR Stainless spade . Tried it still in the hole reading 29/30 .By this time Randy and Kev had appeared . Randy gave it a swing hhhuumm summet there DEEP . So I dug 4/5 inch out with my digging tool place it on the side looked .Could see a silver glinting in the muck . I pick it up gave it to Randy .he said its a bloody Denarius and an early won .'Turned out to be a Vespiasian . 69/79 AD . My first Roman Silver and a cracker . I ended up with 8 roman bronzes and the Denarius . nice roman brooch . Randy really cut it up 22 romans and other bita and pieces .Kev had 8 and a very nice snake item (*brooch) ??? Se if I can put some pics on . Well done Minelab on producing a fantastic coil WHICH will stay on the Noxie .

Matt cheers

G'day, I have been a very lucky guy to have been using the new Equinox 15x12" coil . I decided not to tease anyone with threads about it until it was out there and becoming available to the public. As they are starting to trickle through now I will now say what a awesome coil this coil this thing is. Light for size, very sensitive for a big coil, good pinpointing and really great depth ( depth at the beach amazes me and gives me a workout to dig targets ), Its Spring here and I am just getting back into the water with the warmer temperatures so hopefully some gold jewellery will fall in my scoop . Even though Winter at the beach here is a bit slow, I have done some wet sand + some shallow saltwater hunting when some very low tides occurred. This 15" coil is stable (as good as the 11") in the saltwater and IMHO it is not difficult to swing underwater in light - medium wave action. Most of my hunting has been for modern coins in parklands and a few beach hunts. I have found stacks of $1 and $2 coins and almost least one ring every time that I have had it out...most have been silver - one gold ring to date. The 11" coil has not been back on my Eq800 since I have had the 15" , the bigger coverage it provides suits my style of hunting very well. So if you are thinking of a good Christmas present for yourself this is one that I highly recommend and is one that will probably pay for itself in no time. cheers from Downunder and happy hunting ?

Hello Has anybody tested I am not sure MX Six Shooter vs Detech 7" shooter coil, at colonial iron filled sites and which performs the best? are they still making MX Six Shooter? as I see unavailable on whites site? thank you

I don't go near water, which headphones should I buy? is there a way to set up headphones as wire less? Also best coil at colonial iron filled cellar holes?? Thanks

I just got my 6” coil, and a dedicated lower rod is on the way. To make on-site coil changes fast and easy I came up with the following system. Each lower rod and coil have the cord fastened near the bottom with just enough slack to flip the coil flat for my carry bag. Then I made the straps shown with adhesive backed Velcro from the $ store. The soft part goes around the middle rod by it’s adhesive backing. But then it extends 2” and the hard part of the Velcro goes on the sticky side of it so one side is hook Velcro and the other side is loop Velcro and then it is trimmed narrower with scissors. I have one of these on either side of the folding mechanism I installed on my box shaft. What saves time in the field is that these straps stay on during coil change and securely fasten the coil wire. Also, in my case with the folding shaft I used zip ties to make a loop in each coils cord to go where the folding mechanism is where the cord never interferes with the folding or unfolding of the shaft. I will keep the other coil in my detector bag so I can change the coil during a detecting outing it the situation warrants it. No big deal but easy enough that others may consider doing this method of strapping. A

My Technetics G2 with a NEL 9.5 x 5.5 Sharpshooter coil has turned into a new machine. I'm getting 2.5 - 3" more via air test. Very stable. I'm near a TV transmission tower and the EMI is terrible. With this coil I get set the sensitivity up 3 more notches. Out in the field away from EMI I can crank the sensitivity up to 8-9 out of 10. in mineralized rocky soil. I'm liking this coil !

Just saw a Facebook post on a Kruzer group. Says NEL coils will be available soon. Anybody hear anything about this??!
