I was looking through several different coil manufacturers websites and trying to see if any of them offered stacked spiral coils outside of the GPX-6000 coils. There coil descriptions are usually pretty vague and I could not find anything mentioning stacked spiral windings. From what I have been told the stacked spiral or also called semi-spiral coils for the 6000 our stacked 6 wide and 5 high. This windings type gives the 6000 great depth on small bits. Has anyone heard of or used this stacked type of coil windings on any non GPX -6000 coils.

The availability of the NEL Snake for the legend was discussed in this thread In that thread I mentioned I was new to detector prospecting and wondered if the NEL Snake would be a better nugget hunter over the stock 6" Legend coil. Clearly the Snake can get into spots the 6" cannot and that alone MAY be enough reason to buy one. When I looked at NEL's site I noticed the "Sharp" coil. https://nel-coils.com/index.php/en/production My novice take is the Snake covers a bit more ground, gets in tighter spaces and has slightly better separation. The Sharp covers less ground than the Snake or my stock coil, has a bit less separation, but a bit more depth than the Snake, and being only 5", I still get into slightly tighter spaces than my stock coil. The Sharp seems attractive for the smaller size (Compared to stock) and more depth. But if the depth is no better than my stock coil, and there is no other benefit beyond being 1" smaller than my stock coil, I'd just go with the Snake for the size/shape advantage. To those with actual experience, is my thinking sound... anything I'm not considering?

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.

VMI went out today, it was beautiful. Wanted to do a bunch of testing and comparisons on coils and depths between a vlf and pi. ( So i know where the cross over is ). When I got to the stock 11" dd commander for my 4500 it didn't work. I mean I waved it two inches off my pick before it responded! I looked the whole thing over but can't find the reset button. Any words of wisdom? I've included pics top and bottom for reference. And fat fingered the pics, sorry. I think I'm going to ever so carefully take it apart with a two pound hammer and see if I can find the problem. On the other hand I can now fully justify a new aftermarket.🤠

I was just curious to know if the AlgoForce runs bundled or spiral coils optimally? I know it's early days to know definitively but is it safe to assume that the AlgoForce isn't too fussy in coil configuration. I know there is mention of the older Gold Search coils working well as do the Evo line of coils (Spiral). I guess this leads to whether either of these coil formats would be best in hotter ground? Thanks for any feedback. I only own 3 mono coils that I use with my GP3500.......my all time favourites.

I keep reading in a few different post (To Not Turn A PI On Without a coil connected) I have not attempted to do so because of reading what I quoted, but have often been curious as to what would happen if one was to turn a PI on without a coil connected I know with a VLF generally you will get a coil Error pop up and for instance like the Legend the Legend will shut itself down with out a coil attached so can someone explain to me what happens if you power up a PI with out a coil attached (Just Curious) also why do manufactures not put in a fail safe to prevent a PI from powering up with out a coil connected, if it can cause harm to a PI again just curios because of a statement in one of @Steve Herschbach recent post

I have an Axiom and a good old AT-Gold for hunting in water. I've been trying to find out why Garrett favors blunt ends on it's coils. I've found one brief reference in a forum that the design provides more depth on the front and back end of the coil. I've also seen a reference that stated that the rounded corners may be the hottest part of the edge. They seem to use this design for both DD and Mono coils across all of their products. Can anyone talk about the good and bad aspects of the blunt end design? Why is the round coil design better or worse?

Looking into purchasing an aftermarket coil, equivalent to White's DD eclipse for an MXT specifically. I really don't know whats out there from other manuf. Looking for a HOT (sensitivity/depth) coil. Better target separation is a plus too. Or would you recommend I stay with whites coil? Any experience and feedback would help. Thanks, TC-AZ

Anyone know what types of plastics all the manufacturers use? I am looking at printing some skid plates and coil bodies if I'm able to get some time to experiment with making my own coils next season if this Algoforce rolls around and we have use for non-chipped coils again. I can 3d print strong plastics like polycarbonate and nylon, leaning towards one of those. But I'm just curious, is there an industry standard for the types of plastics used for the injection molded coils? I feel like maybe nylon, but I'm unsure. I like the idea of transluscent polycarbonate coils so I might try that first (inspiration from Strick's x ray posts). Seems like the cheaper spools like PLA, PETG, even ABS all might be kinda too weak. I know layer adhesion makes 3d printing non ideal for wear parts, but the ability to quickly print and prototype different geometries seems compelling for experimenting. Anyone know what like NF uses for example with the modern coils like Evos? Anyone printed a coil yet and determined how robust (or weak) it is compared to injection molded of same plastic?

Has anyone ever used both or at least the Detech and have any comments at all? I'm confident enough in the Commander but wonder if the Detech might be a better option. Basically going to use for looking for coins and better yet rings at the beach so don't care about hitting tiny bits, in fact prefer not doing that. Detech has the spec edge at 780 grams versus Commander at 820 grams. Detech is rated waterproof whereas Commander is only rainproof. Commander coils I am pretty sure are Litz wire. Not sure about the Detech.

I was on a trip, using my Gold Bug Pro device with the standard 11-inch search coil, and suddenly the device continued to buzz with the Overload message appearing. I moved away from the place, but nothing changed. I raised the detector high and nothing changed. I also tried the other 5-inch disk, and it was normal. I expected a nail or Something similar entered through a crack at the base of the search file. I dismantled the damaged file and did not find any indication of the problem... Any help is welcome

So I read all the old reviews on here for the GPX17 coil for the 6000. Is everyone still in love with this coil like the old reviews indicate? The 6000 is my primary gold detector and I dont have a 7000 or 5000, and I also know the 6000 will never match these machines regarding depth on larger gold. Is the GPX17 still a good coil to have for patch hunting in open ground and some extra depth compared to the stock 11 inch or the NF 12x7? I was patiently waiting for the NF 16x10 mono coil to be released but it does not appear like this is going to happen any time soon and maybe never. Please advise if the GPX17 is a worthwhile investment now or should I wait for another year to see if the NF coil will be released. I have not seen any field test results comparing the GPX17 to the NF 16x10 even though it appears that JP and maybe others have tested it. Please advise, Ceril

I bought somebody's GPX 4500. It came with 4 coils. Then I realized that I don't have a clue what are the strengths and weakness of the different coil configurations. What are some general principals to guide folks in matching coils to the situations that they encounter? I don't recall having seen any guidance on this. Thanks

Anyone know of any person or company, worldwide that sells coil shells? Thinking about building a smallish CC coil for the Legacy Minelab PI's. I only know of a Bulgarian and Ukrainian seller but neither has coil covers to accompany their shells. The Ukrainian one (Pictured) is only a 9", so the receive coil will be C.5" at best.....so should be sensitive but not great overall depth for larger targets. Any ideas????

I need some help in Choosing which big Mono Coil to purchase for the Axiom I currently have the 13x11 DD and the 11x7 Mono which were in the package I purchased, I also picked up the 11x7 DD I am wanting to add one of the big Mono's for the Axiom, but can not decide if I want the 13x11 mono or the 16x14 Mono Someone please sway me one way or the other LOL How much depth will I gain with the 16x14 Mono over the 13x11 Mono if any, I know this depends on several things ??? how much sensitivity to smaller gold will I loose with the 16x14 Mono or the 13x11 Mono if any ???, I also know there is to many factors to consider on this one also price is only like $20-$30 more between the two so not an issue in my opinion So there is my dilemma, so again give me some reasons to choose the 13x11 mono or the 16x14 mono for me it keeps coming down to (if I am going to go big go the biggest I can currently purchase) LOL Thanks for reading my RANT

I tried to finalize the purchase of a Troy Shadow X5 coil and it seems that the only way to pay is by making a deposit into a bank account, money order & money gram, which is strange or suspicious for any company that considers itself serious. Note: The same coil is on an auction website for twice the price.

Looks like M15's are hitting retail at the moment, a guy in NZ has secured one, not me unfortunately, I may have been to slow to order by the looks of it but at the early stages I wasn't even sure I was going to bother with my Manticore, now I've decided I'll give it a chance. Hopefully my spots not too far away. I've ordered both coils.

On all my VLF detectors I usually run the coil cable straight up the top of the shaft securing it with Velcro type cable straps, I usually do this all the way up the lower shaft and then wrap the coil cable around the Mid shaft to the control housing, this has always worked for me my question is, is it ok to do the same thing on a PI like the Axiom or should the coil cable be wrapped all the way up the shaft starting with the first wrap over top of the shaft ???, or is straight up the shaft ok ??? in the photo is how I have the coil cable on my Axiom

Just curious if any of you folks still use a concentric coil and if you do, when and why versus a DD. I picked up a Tesoro Sidewinder with the 8" concentric coil a short while back and did some parking hunting with it last week. It did remarkably well. Yes, I did dig more trash than I would with my Legend or Equinox 800, but the Tesoro did reward me with a good pocket full of clad and a shallow wheatie. I had forgotten how easy it was to pinpoint with a concentric coil. And the detector was really fun to use. No updates to install, no menus to trudge through. Don't know if I will use it a lot but it was a nice change of pace. Bill

I bought several coils over the years for my GP Extreme and just now am getting around to trying them. I discovered that some DD coils wouldn’t work - they result in alternating high-low tones without sensitivity to any targets. Is this indicating an issue in the coil or more of an incompatibility. The manual says some coils can act erratically - is this that?

Oh crap. I get out my GPX coils and find 3 with bad cable insulation, the inner plastic insulation may be brittle too. They don’t have a shield so I’m wondering if some thick stranded AC power cord cable may be a sufficient replacement- any thoughts?

Today I had a conversation with a colleague in which we talked about being able to use coils from one brand in detectors from another for which they were not manufactured. I stand aside due to my lack of knowledge, but he argues that it is possible to adapt certain coils that were not designed for a detector for which they were not designed. Is that possible? Making mods is one of my favorite hobbies so the topic caught my attention. Specifically, we were talking about placing Whites coils that are used in the M6, MXT, BHID, DFX and some others that I don't remember, and installing them in the fisher cz21, cz3D, which share similar frequencies, configuring adapters and wiring. Do you think this could work?
