Over the years I've had several old sd detectors and collected a batch of coils. These 2 + the 18" garbage can lid. The ones in the photo are 8" and 10 1/2". They are not marked mono or dd. How can you tell what they are?

If you talk with a gold prospector, saying about a gold chain as the hardest item to uncover, it is a joke. In my still modest 20+ years experience, I found no more than 12 or so. Every time cause of a pendant still there in the same hole, or at least an eye visible piece. Long story short, I found at some depth (2" more or less) one little pendant with a weight of only 0.32 gram. I know, the shape can do miracles in terms of response to the coil, but hey...With the M9 this opened my eyes and that's the reason for the title. There will be no more progress on a Vlf to avoid salt and listen to chains. I'm sure now. Still today, smaller items barely covered in sand can be reached but forget about decent depth perception of it, not underwater. The low conductors program performs to a limit where I can barely realize if I'm running way hot at 22 or something reacts for real to the coil. Wrong program underwater, wrong approach to the usual work, I know. Using different settings and programs will only get You a blind machine like many others on micro targets. Steve explained long ago the "salt against chains ratio" and now, again I crashed my nose on it. For peace of mind, I'm considering to stay for some time with a pulse machine and forget micro targets for a while... I think that I've been lucky enough to push the Manticore to the limit underwater in salt. Skull

I watched a test on a test-bed where a 2oz lump of lead was detected at its max depth with BOTH the stock 14 DOD and the 19 DOD. Same depth, same settings, same signal strength, the 19 provided absolutely zero benefit. The owners played with it for hours on 2 detectors....then gave it back to the Gold Center in Maryborough. None of the 5 Zed owners present, bought one. Not saying that the coil wouldn't have some benefits on bigger targets or worse/better ground conditions, but that day's 'presentation' didn't sell any....

Let's say I'm getting a gpx 5000 / 4500 and going to use it in the Victorian gold feilds (Australia) What coils would you recommend to have to cover most situations. Thanks in advance Roy

I recently bought a GP3000 which came with a few coils. When winding them around the detector shaft the outer cable started peeling off. I've got some dual-walled heat shrink that I was going to apply, but I'm not sure about the white paper that has also peeled off in some areas. Any suggestions about what that white tape is? Or what I could use in place of it? The coil has barely been used but I assume storage wasn't the best as my 2200d and its coils are older and the cables are still in good nick. There is a possibility that the internals of the coil have dried out and the windings move, causing noise but I'll attempt to fix the cable first and see if it works first.

Is the Coiltek 14" DD waterproof? I know my 6" Coiltek is waterproof as I've used it in 2 feet of water. The other coils in the photo are 8" and 11" Super Goldsearch coils, are they waterproof? They are old so that worries me somewhat. What happens if a coil was to let water in? Would it kill the machine? I have had a coil in the past signal coil overload before when the grass was wet, but fully submerged is something else I presume.

I was wondering what you serious “Water” hunters use to weigh down your coils. Someone once suggested taking a “tube” sock, filling it with sand, tying it in a circle (like an ankle weight) and sliding in over your lower rod having it lay on the coil. I’ve also seen bandanas (to keep you cool) with Silica Gel sewed in to them. They absorb the water and expand making them heavier than they are dry. I wonder if you had enough in there, would that work also? Thanks!

Something I have wondered for some years now and have never asked, especially as there has been close to a 4 years hiatus for me in getting out and detecting- Is there a correct way to store a metal detector coil? Laying Flat maybe? Hung up on the wall on a hook or nail? leaning against a wall, left on a detector etc.,?..... On various forums and in different photos over the years I have seen them stored in all of the above ways, which also makes me think that perhaps it doesn't really matter either way? Also, with the exception of my Detech 32" CC I have simply left the small DD & Mono coils that came with the 5000 sitting flat in a cupboard. The Detech has its own foam-lined hard Pelican case, but do I risk warping/ affecting a large coils operation if I leave say my NF 25"DDX coil leaning up against a wall? There is no other option for leaving larger coils laying flat where we are currently living without risking them getting damaged. Thanks in advance, -Gary

I'm recently short of time to search, but almost sure there's still no trace of a 10x5 for the Manticore. Even if really satisfied by the 8x5, trust me, the exact same 10x5 for the Nox will be my last Coil when this happens! @Coiltek Do the miracle please...

I recently purchased the excellent LG 24 coil for the Legend for under $130. Why are similar sized coils by Coiltek (Equinox)and Minelab (Manticore) coils twice that price? Are they twice as good? lol

Anyone know for certain what the MX stamp on the coil ears means for the 6" DD Shooter. I know the V stamp stands for V rated and will work on a variety of higher end detectors, but what models can accept the MX stamp? I was always under the impression the 6" DD Shooter was originally designed for MXT but then White's started making different versions of MXT (will this coil work on all of the different MXT series) and to make things even more complicated, they then made a detector series called the MX. Could this coil stamped MX, only be used for those MX models? I don't think so, since the decal is exactly the same as the one for the MXT. Thanks folks your help.

The other day I ventured into a not so hunted area of my permission. It is a steep hill on the backside of a cut stone foundation... No doubt an embankment where the inhabitants tossed their discards long ago. The incline is tough as is the ground. The ground there is like cement as large Locust trees help shield rain. The finds were not deep, possibly the deepest being 6", but the entire hill side is blanketed with small square lathe and framing nails. I generally don't use discrimination on my Apex and I hunt with wide open sensitivity. I listen for pitch level and watch display readings. My iron volume is set lower to "2" allowing me to hear the nail concentrations, but keep my sanity. I have always liked Garrett's elliptical searchcoils starting back with the AT-PRO for their shape, quality of construction, and the ability to hunt closer to objects like rocks and trees. Today I was hunting with the elliptical stock coil "Viper", 6 x 11". When I first purchased the Apex, I did some air tests to see the extent of the coil's unfettered electromagnetic reach and I was surprised to get a small clear signal on my custom 14K gold wedding ring at a measured 14". Hunting the embankment was difficult. You lay the detector down, it wants to slide down the hill along with yourself and your digging tools, but the chances of finding targets here was fairly good. In one hour I found the targets in the first photo below. The targets were tough to discern mixed with the nails given the Apex has only one processing speed... But that speed affords good depth amongst target concentration. Two days later I would saddle up Garrett's smaller elliptical "Ripper" coil (5 x 8") and head back to the embankment. It was a calculated purchase awhile ago, but I had yet to really give it a workout. As a side note, before I left I did the same same air test with my wedding band and was again surprised to find it had nearly the same reach as the Viper coil. But how would it do given the smaller footprint? As a test, I carefully hunted the exact same areas to see if I could define more targets amongst the chatter. As you can see in the photo below, I found twice what I found before! Signals were easier to confine and all were found at the same depths as the stock coil. The spoon was actually buried vertically with the bowl deepest in the ground. As I brushed the leaves away I could just see the handle's back edge at the surface. Even though the Viper coil weighs about 1.0 lb., it is still nice to swing in high grass, but the little Ripper (0.8 lbs.) is an absolute crowd pleaser! Less resistance to grass and weeds and the depth is not too far from the Viper. What I came away with from those two days is the Ripper forced me to hunt with a slower swing speed given less ground coverage. Slower works well to give the Apex more processing time between crowded targets... Also, not as much depth loss as detectors with higher processing speeds. I would not want to hunt farm land with smaller coils because the matrix is not as crowded and you might miss those targets on the fringe of detection depth. Cellar hole grounds is where the little "Ripper" rips it up!

Woody's done a decent video on the chip in the 6000's coils. It's there for absolutely no reason other than being an authenticator to prevent unsanctioned aftermarket coils. You can read about the security chip here at the manufacturer's website. Video is of the newer model. This video shows how they program the chips, all very interesting stuff. There were rumours flying around Nugget Finder did this wrong when the Xceed coil was delayed, no idea if that was true, probably not. It's really not all that hard to do a dongle using the chip, the only thing different to the GPZ is you have to cut open the coil to make it a donor coil rather than just chopping the cord like the GPZ, the coil can work on the dongle without a chip in it so can still be used but I think many aftermarket coils are more likely to appear once GPX's are out of warranty and the stock coils are prone to failure so once people have a heap of dead genuine coils what other use do they have other than dongle coils 🙂 It's a shame Minelab are so against aftermarket non-sanctioned coils, they're holding back their detectors doing this, I suppose it makes life easier to bring out future models by doing so with self-imposed performance restrictions though. The funny thing is another common use of that chip is printer cartridge authentication to prevent people using aftermarket printer cartridges. We all know the agony of buying printer ink. There is big money in printer ink, Minelab gold detectors feel like they're worth their weight in gold, printer ink actually is worth more than its own weight in gold :)

It's great to see Nel still around, they've survived the odds so far and now they've released their range of coils for the Legend. Legend owners now have an additional 10 coil choices for the detector, and this will mean it's fiercely competitive with the best of the best from any brand. That 17x15" Nel Big would have to add some depth, then the absolute tiny gold nugget (flake) sensitivity of the Nel Snake at 6.5 x 3.5. The Nel Superfly and Tornado are also coils to take note of. It was always my condition that I wouldn't buy a Legend unless it had Nel coils, as I have too many detectors and adding another similar one would be a pointless exercise for my needs. However, now with Nel having their range of Legend coils available it is a must have detector for me, the Legend paired with a Nel Snake coil would be a beast for prospecting. He's a link to the Legend's Snake coil. https://nel-coils.com/index.php/en/production/nel-snake-9-5x3-5?id=2376 I'm sure they're going to be hard to come by at the start, and no doubt expensive as shipping from Ukraine at the moment is sky high, a price I am willing to pay though, this has to be a giant kick in the marbles to Noktas competitors.

Hi, I’ve been looking for a used 11 inch equinox coil and saw a significantly less expensive one on sale that is in almost new condition except that the cable was accidentally cut in half. I considered getting it as I can repair it properly because I used to repair underwater velocity meter and transducer cables at work. My question is do Equinox coils also contain an internal chip? If so, should I be concerned about it if the detector and coil were not energized when the cable was cut? Or any other possible issues doing this type of repair? I’m pretty competent about doing the cable repair itself, including properly replacing the shielding and making it waterproof. My main concern is what could’ve happened inside the coil. Thanks!

Does anyone have any experience with these Fisher/Tek coils? FirstTexas has them listed on eBay for most of their machines. I remember seeing them in the past for F75 but never heard much reporting on their performance.

Although I will not have a chance to test this coil on the seabed until next Monday, an initial test in the air has me very curious... A few days ago, a user on YouTube complained of considerable noise, very similar to the M11 at the beach with even lower sensitivity, so much so that it could not exceed 20 points. To my surprise, what I noticed instead is that the footprint of this coil does not seem to respond as strongly as on the 8x5". Let me explain, apparently, the lateral response is much less pronounced and sensitive, compared to the obvious center part between the two rx and tx parts. It would appear to be something like a concentric plate, rather than a double-D technically speaking. With fully open pattern and lower separation speed, the differences are practically zero. Talking about sensitivity, 22 as last option before falsing yet in the air. The question certainly arises at this point about effective in depth coverage, rather than mere surface coverage. It is very likely that the difference in depth is almost zero and that the greater amplitude beyond the elliptical perimeter of the M8 is marginal. We shall see...

Actually not much to report for this week, if anything the M9 had a fairly quick break even with three rings under its belt. Two of the three, were recovered last week and thus not new, but the third turned up Tuesday morning after sunrise buried well over 10 inches...No wonder, considering the 7.77 grams of 14K. Bad surprise was the acid test, where just the heaviest one turned out to be 9K complete with a 585 mark typed inside. A real scam into which the owner also fell, because inside it bore the bride's name and thus a fake wedding band or at least passed off as 14K but with much less real value. (This ring appears next to the M9 logo). About the M9, there is little to be done, once in the dive, exceeding 20 points of sensitivity with beach LC, is out of question.With the M8, one can dare a few more points and given the non-appearance of broken bracelets or necklaces, I will return to use it soon. Definitely the M9 is more akin to rings, but not to links in bracelets and necklaces. Have a great weekend to all of you!

Coil Compatiblility Across Minelab Line? Help!
Vance in AK posted a topic in Minelab Metal Detectors
I currently have an SD 2100v2. There may be an upgrade to a new machine in the future, but thats not the question. I would like to know what series coils will work with the 2100v2. Will coils labled GP Extreme work? I know one of the coils I currently have is marked GP series. As I said, I may upgrade someday so also asking so I know what machines my current coils might fit I is lost!!! -
I've got a lot of clad coins I was going to cash in. Coinstar has no fee if you put the coins into a gift card. Anyone know of a seller that sells coils on Amazon? I've looked but only see full machines.

A MD dealer/distributor from Canada has some rare Tesoro coils listed on ebay. There is an elliptical for the waterproof PIs (sandshark/piranha) and the 7” for the waterproof vlfs (tigershark/stingray). They have a couple others for the land machines as well. I finally managed to get a 4” concentric and a 7” widescan! https://www.ebay.com/usr/cts300551
