What is the best aftermarket coil for the Bounty Hunter Time Ranger Pro, Teknetics G2+, Fisher F-19 and Fisher Goldbug Pro (they are all more or less the same detector)? NEL, CORS, MARS or Detech are the choices.

Does anyone know whether Miner John has been successful in rebuilding his manufacturing facility after it burned in the fire? I am entertaining the idea of buying one of his coils if and when they once again become available, and am just curious. I certainly wish him the best.

Wow I can't believe I got out yesterday to dig. It seems like work and the stress of things in 2020 took a toll on my detecting experiences for quite a while. I wanted a new coil for the MK and saw a post Kac made about the Nel Superfly, So I said what the heck I'll give it a try. This coil is 6 grams lighter than my 9 inch. I must say this coil is amazing!!! great depth and way better separation. So I went to give it a spin on a site I hunt that has some modern and 18th century history to it. (ball fields and farm fields). I swung for about 5 hours in the 35 degree weather, and found a bunch of coins,(1941 penny, 46 nickle) shot shells, suspender clip, fishing reel, and a fragmented old bell. I wish the bell was whole, because it was about 2'' in dia. The reel perplexes me because of the lack of water in the middle of a 20 acre field. Overall I had a really nice trip out, I was starting to forget how detecting can clear your mind. PS Joe D can you please send some of the Florida warmth up here to PA.

Hi i have one question . Its possible change coil conector ? ( fits AKA coil to Garrett? )

I've always wrapped the coil wire around the shaft a few inches up from the coil. But then I saw in a some people mentioning they run the wire straight up the lower shaft then start coiling the wire above that. Someone mentioned the reason he does this is because of the magnetic field and possible interference wrapping it shortly above the coil. I have only been detecting about 7 years and always trying to learn more. Any advise/suggestions ect. on this would be great and thanks in advance.

I’ve been dithering on the 15 inch coil for my Noxy 600.... I mostly do beaches here in So Calif..... I’ve been doing ok with the 11 inch that came with, but am not sure if the 15 in her would be an advantage..... what are your thoughts? ? ?

Hi Folks, I'm developing a new VLF analog prototype detector and am using a concentric coil I've seen in the book "Inside the Metal Detector", it has the TX coil in the center with upper and lower RX coils that are balanced. So I have some questions for you experienced folks: Does anyone know if this style of coil is still used? If not, does anyone know why it fell out of favor? Any pro's and con's? Thanks for your help, I'm considering showing some of the pic's as I progress, I have the next revision pcb on order, we'll see how it goes.

I did some testing in my back yard to compare relative depths achievable in my soils with various coils on the Fisher F75. Caution: these are relative measurements specific to my soil conditions (including ferromagnetic mineral content and current moisture content). The purpose is merely to compare coil sensitivity for particular settings which push the detection depth limit under these conditions but otherwise should not be used as an absolute indication of how this detector with these coils mounted will perform under different conditions by other detectorists. My ground is of moderate mineralization, measuring 2-3 bars on the F75 depending upon exact location in my backyard and coil choice (higher reading for largest coils). Detector setup: Fisher F75 Limited (black) operating in motion 'all metal' (USA nomenclature, not Minelab's!), DST on, gain=99 (max), ground balanced, noise cancelled, threshold=0. I plugged Garrett GS2 headphones directly into the socket, i.e. 'wired' headphones. Test targets: 5" deep 95% copper Memorial USA 1 cent, 6" deep 25% nickel, 75% copper USA 5 cent ('nickel'). (These have been in the ground ~ 2 years.) Measurement meaning: because the coins are at fixed depth, in each measurement I raise the coil until I lose the signal in either left or right swing directions. That is, I require the target to sound off clearly as the coil moves from left to right and from right to left. I use wood blocks as shims with a least significant thickness increment of 1/2" (~1.3 cm). I estimate half that or 1/4" as the measurement's systematic uncertainty. Note that these measurements are intermediate ('hybrid') between full ground and an (full) air test. Coils tested: Fisher stock 7"x11" DD and 5" round DD (both included in the Limited/black model package), Coiltek 6" round DD prototype (built for Fisher F5 and operated successfully on my Fisher Gold Bug Pro), Mars 6"x10" DD Sniper, and Detech 13" round DD Ultimate. (I forgot to test the only concentric I have for this detector -- Fisher 5.5"x10" which is the stock coil on their F70. I'll do that later this week and add it to the table below.) Results: Summary/Conclusions: With the exception of the yellow-highlighted Coiltek prototype (which was not designed for the F75), the order of depth does reflect coil size. The Mars 6"x10" DD performs almost as well as the stock Fisher 7"x11" DD. The largest coil, the Detech Ultimate, is only a bit better than those two which likely reflects the considerable increase in ground it 'sees'.

I haven't used my Treasure Pro in about a year and it has been packed up and hauled around a bit. I turned it on and I get random readings all over of the scale. I followed the directions to reset it with no change. If the coil is not connected it is quiet. Could I have a broken coil? Dan

I was thinking the other day about some of the best metal detectors of the analog age and early digital age. My memory shows concentric searchcoils, the Fisher CZ series being an example. What is the earliest commercial detector that had the commercial option of a DD coil? (As opposed to prototypes, experiements, garage builds, etc., although if you know of any of those it would also be interesting to read about.) Were there analog detectors (and if so, which ones) that worked with DD coils or did those not come around until digital circuitry took over?

What is wrong with the Gold Kruzer? Why doesn't NEL or CORS or Magic or Detech make any coils for the Gold Kruzer? They make full lineups of coils of for the Gold Racer, but not a one for the Gold Kruzer. You can't say its because of the water proof connector, as they make coils for the Kruzer and Anfibio. You can't say its because of the frequency as they make coils for the Gold Racer and the Gold Kruzer is basically a waterproof Gold Racer. So what gives? Why do the aftermarket coil mfg's treat the Gold Kruzer like an ugly step-child? Mike

I leave you a video in case someone wants to do it. Having two dishes to choose from, I don't know if it's worth it. Although it must be recognized that the plate is much cheaper and larger. The video is in Spanish but the procedure to do it looks pretty good.

Finally got a Superfly for my Multi Kruzer. It weighs just .01 lbs more than the stock 7x11. Overall it is less chattery and I can kick the gain up much more. Depth wise on a silver dime it at same gain settings it will go between 2"-3" deeper with steadier numbers. Target separation seems to be about the same and in the field I gave it a go for about an hour or so and it was really nice to swing. Though I only found a bit of clad I plan on giving this one some serious hours. Not sure if it is a worthy upgrade for anyone with an Amphibio but if you have one of the Kruzers I highly recommend it.

I was listening the other day to C-Scope talking about the new Evo-6000. They said they opted for single frequency operation with the coil set for one frequency as it is better as it resonates at it's design frequency, in this case 17khz. They did say there will be option coils to change the frequency higher or lower but this will mean purchasing a new coil to change frequency. Is this truly the best way to achieve the best sensitivity at a given frequency or are they just holding on to old tech. There are other makes of detector that you can change frequency with the same coil (Deus, ORX, Kruzer, Anfibio, Nox etc) do these machines have a set resonate frequency matched to the coil which offers best performance and do they lose sensitivity if you change frequency? Or is there a way of making the coil sensitive to a range of frequencies. Just wondering why they chose to go a different route to others on the frequency selection?

The coil cable has developed what I think is a discontinuity on one or more wires at or in the molded plug. Plug says: "Amphenol". There are 8 conductors. Does anyone here know the part number for a replacement plug to fit the jack on the rear of the MX Sport control box? 50 years ago I soldered a shortwave radio kit together; I'm quite rusty, but perhaps I could solder a new plug on (doesn't NEED to be waterproof). TIA!

This is a Garrett forum for people who like Garrett detectors, so they can learn about how to get the best out of them. If you want to compare brands, or just state your negative opinion of Garrett or it's products, please use the appropriate forums, like the Advice & Comparisons Forum. Thanks.

Just got bitten by the broken coil ear bug. Have had the Nox for 2 years and thought I was special because mine hadn't broken yet. It is on it's way to PA. Wanted to get one of the stiffener devices to put on the new coil for insurance. I've read a couple of horror stories of both ears breaking off after using one. I was leary of just buying from eaby or amazon. If you use one who did you buy it from and how has it worked?

⁉️ Which one is better? Has anyone done a comparison test between the two coils for a jewelry hunt in the water? (freshwater or land) Both are able to use the same frequency. 28 kHz is very good for detecting gold. When I hunt in the water it is a very useful feature of target ID normalization. On the of LF coil, this was a big advantage. I set the gold range, so I only dug out the signals that belong to it. The HF 9" coil is great, but when I increase the frequency the VDI changes, getting higher and higher. The upper range will become narrower. This makes it difficult to decide whether to dig or not. Let's look at an example. A 1.5 g 14K wedding ring is the test object. HF 9 "coil at 14 kHz = ID 50, 28 kHz = ID 65, 56 kHz = ID 79. X35 11 "coil 11.3 kHz = ID 54, 16.4 kHz = ID 54, 25.4 kHz = ID 54! If I use frequency offset these numbers will change a bit. The general opinion of many people is that the HF coil is the best. I'm not so sure about that. I looked at this idea in terms of the gold jewelry hunt.

I finally got my old 11'' replaced. This new coil is working great and I couldn't be more happy. Thanks to Dilek all my problems have been resolved. Yesterday and today were the first times I have given it a good run. I decided to hunt a farm house yesterday. I usually think the finds are getting low. Well low and behold I was wrong. Yesterday was good and bad as posted on the coin and relic forum. Today was even better!! same farm plus a kids camp. In two hours at the farm I scored a 2 oz. sinker, a bunch of odd lead, 2 wheat pennies, a girl scout pin from the 60's and two fabulous 1952 and 1957 roosevelt dimes. Around 1:30pm I decided to hit the camp. In another two hours I scored $1.05 in clad (not much) and a very awesome 1810 to 1830's button. inscribed on the back is Treble gilt Standard colour. seems to be a british button. Most of the clad from the 60's and 70's were at 6 to 7 inches deep. this button was around 3''. I did dig a bunch of deep trash always looking for the gold rings. The only thing is the id numbers are a little off, they are a couple of points off, but that was an easy learn. I'm thinking the old coil was bad from day one and today just proved it. I can't wait to hit some more of my sites and see what I missed with the old coil. The MK has yet to let me down and has been a great machine in the short time that I have owned it.

I just got word today that the new lightweight 15” coils are in production. I have a prototype for the T2 - it weighs 750 grams (26 oz.). MSRP is $149. If anyone wants one, I can get it shipped direct from FTP to you. It looks identical to the previous 15” coil - just made with different epoxy and much lighter.

Hey guys, I've been doing some reading on Mars Lion 7" coils to see how they might compare to NEL or others but coming up a bit dry. Saw something about the MARS coils maybe being more sensitive but noisy. I really like the way the NEL are built, as least externally. Would be great to see the construction too, can only hope.. Looking at the Mars Lion, NEL Sharpshooter / CORS Fortune, and maybe the 7 or 9" Nokta Makro concentric for kind of a smaller coil to user in dense areas with an Anfibio. The primary now is a NEL Hunter 12.5x8.5. Really "digging" that one, so much so that I got one for my E-Trac and Anfibio both. Doesn't have to be for the Anfibio but if anyone has experience with these makes with other units it could be helpful in hearing how they run and any pros/cons. Thanks and HH! Mike

Does anyone know how to make coils for GPZ detectors? Or is anyone aware of companies that make coils for minelab detectors???

Been keeping my eyes out for the Nel Super Fly or CORS Butterfly 12w X 11 long coil. Weighs 420g. Seen some for Garrett AT Series and ML Soverign. https://corscoils.com/product/butterfly/ Hopefully more will come over to the states. Looking for a bigger coil for my MK.

I have a Sovereign XS2-a Pro and was looking at aftermarket coils. Any of you fellas use one? Does it go deeper than stock 10 inch coil? How's the stability? Any other coils you guys use/recommend?

After a busy week, doing an effort between heavy rain interruptions, I finally finished this work! Thanks for all people involved in this project for their knowledge shared... Underwater test next week(I hope)
