I recently broke my stock dd and replaced it with the 9x12 concentric. For the life of me I could not ground balance the machine in snow, just an inch or 2 it would false out like crazy. I did repair my dd but it is slightly out. Sent the 2 coils to Garrett along with the AT Pro and they repaired the machine, put in new firmware and confirmed the dd was out of wack. Went to use the machine over the weekend and still can't gb it with the concentric. Does anyone have a 9x12 concentric on an AT Pro and can confirm the issue? Not sure if it is the snow or the machine is marginal and sensitive to the cold or not. Thanks

Anyone have any idea why my coil is overloading??? I checked up and down the cable to see if it was shorted to no avail.... It works fine with another coild. Trying to upload or link a video.... Standby---- https://photos.app.goo.gl/W1Nwk2kCRQixPE5H9 BTW Hey all you crazy Aussies-- Im still kicking---hope all is well with you all there...

I was reading about coils. They said a round DD coil has a lot of advantages over football shape coils. It has been a long time ago. Can't remember why ? Any one can help with this?😕

Dose anyone where I can get a coil end that's goes on the black control box. I have a 9.5" coil that someone changed the end for another detector. I can't find where to order on Whites forum. Thanks Dean

When I bought my tdi sl it came with the 12 and 7.5 coil. Recently I have sold the detector but I still have the 7.5 dual coil and I will sell it. Seeing photos to see the price I could ask for it turns out that my plate has something on the cable that I can't see in the images of other dishes I've seen. I would like if a partner could tell me what it is ?. Thank you

I had snagged my dd coil on a log and didn't realize I had put a hairline crack in it until I had noticed it was falsing on me and every time I tapped a small branch or brush it would sound off. I had made a small vacuum degassing chamber/pressure chamber for casting resins out of a paint sprayer and luckily my coil just fit inside. First thing I did was use the vacuum chamber to draw out any moisture. Next I built a small barrier out of some tape, filled it with epoxy then used the pressure chamber at 60 psi to force the epoxy into the crack. Not perfect but the coil does gb now. I think there are internal cracks that would be impossible to fill but at least I have it as a backup until my new coil comes in. My next project I think is to give some lexan sheets a go for coil scuffs that cover the bottoms so branches don't get caught up. Friend of mine wants one for his Nox 800 so will see how that goes.

Guys, I wonder, does anyone know or have a diagram of the coil connector pinout? Many thanks! Apologies, didn't mean to start new topic, but it was moved separate. It may come handy for others perhaps. I'm going to tap into those wires to find out what they are once I have an inline connector made.

These are used in MRI machines. The weight ,cost and flex might work with Metal Detectors For a state-of-the-art 3 Tesla MRI machine, the price tag to buy one new can reach $3 million. I remember a few years ago on another forum suggested a spiral coil using a printed circuit board.

I have a new sharpshooter, but now I want to replace the factory coil on my F44. The one that came with the machine is the teardrop,not a big fan of it. Looking for one roughly the same size or a bit bigger that would out perform it.Thoughts?? HH to all!

Hey all, I just found my coil connection sheared off at the control housing. (oops, and bad timing as I was just headed out!) Luckily no damage to the control housing connection but the other end was bent and broken right off... I sent some photos to minelab to asses if they will fix it or not but still waiting. I was wondering if anyone knows if its possible to buy this connector anywhere? If minelab wont fix it then I will end up splicing one on myself and hope for the best (minus the water tightness of course) . Any help would be so appreciated!

what is the best Coil use gpx4500 for Small nuggets weighing 0.2 g or 0.4 g Elite or N Finder Nuggets And circular or elliptical shape

This is the best video I have seen yet explaining the basics of search coils and why some may be better at some uses than others. By Garrett May 2019.

I just got back from Rye Patch, Nevada; found 14 small nuggets; 6.2 grams total. I found nuggets with all three of my X-Coils; 10” round bunch wound; 17” round spiral wound; and 17”x 12” elliptical spiral wound. I have attached a chart that is compiled from testing of the 10” round and the 17” round coils as compared to the Minelab GPZ 14 coil. The testing was accomplished in a Rye Patch gully by placing a two foot PVC pipe into a freshly dug hole. Gold nuggets of various sizes were lowered in a medicine bottle by a cloth measuring tape. This test was for my own relative comparisons; so those that want to critique the methodology feel free to do it another way. Two obvious depth improvements would be gained by increasing the Threshold setting and using headphones to listen for barely perceived target responses. After discussions with Lucky Lundy and Gerry McMullen I now have found a middle ground that works for me with the following settings; High Yield, Normal Freq. Auto, Sens 20, Volume 12 Threshold 1 to 27 depending on EMI noise level Tone 53, Vol Limit 12 Auto Smoothing Off, Ground Balance Auto, GS Off The 10” is very sensitive but noisy. When roaming across the desert it has me swinging back over false targets much of the time. But it works quite well to slow down and get into small openings between the sage brush and close to bedrock in narrow gullies. Some quick checks make me think that the 17”x 12” will have similar depth performance to the GPZ 14. But will cover three inches more ground on each swing. I will chart some depth comparisons when I get time to do some more testing. I use the 17” Spiral Wound Round coil when I want to cover a lot of desert. The extra inches in circumference with a little extra depth penetration over the GPZ 14 coil is an advantage. At this time I am retiring the Minelab GPZ 14 and the GPZ 19 coils. I have no connection to X coil, or to Davsgold except as a customer. X Coil and Davsgold have both been very responsive to my emails. Have a good day, Chet

Has anyone found a lower shaft for White's TDI to adapt to Minelab coils or coils made for Minelab correctly without extra rubber washers? Tecknetic's lower shaft comes close but is too short.

Does anyone know any information on the new coil for the TDI SL and if the coil will be available separately? TDI SL is now ... TDI Hi-Q A new high performance coil design for added depth - in two options TAN Part Number: 800-0334-Hi-Q CAMO 800-0334-Camo MSRP: $1199.95 MAP: $1099.00

I have had my 800 since the end of April. I have to admit I was a little skeptical of all the hype but after using it a lot I the last 3 months or so , I am very impressed. This past Friday I was at a new site and when I picked up the detector to take it out of the truck the coil fell off. Both the mounting tabs were broken. I am pretty particular with my equipment so I really don’t think it was anything I did. I emailed the repair center and has been my experience in the past, they were prompt in their response and had shipping instructions to me that same day. They said the coil would be replaced under warranty but would take a few days because the service center had run out of coils and they were currently on backorder. This leads me to believe their must be a lot of people who have had the same issue. It will be interesting to see if this new batch of coils has beefed up the mounting tabs. They really are kind of flimsy when compared to the Explorer series of coils. I don’t mind the wait, it gives me a chance to get to know my 6 in. coil.

I swapped out my Nel Big coil on my AT Pro and put the stock coil on and just for kicks I did a quick air test to see if there was any difference and I found that the targets now hit 15-20% further away ie dime at 10 inch instead of 8. For those that don't have Garrett machines and a 3rd party coil, the procedure when changing coil Garrett says to do a factory reset of the machine. So if anyone knows, does using a large coil setting on a stock coil essentially do a tx boost? Do other machines require factory reset after changing coils?

Finally got to work on testing the 7 1/2DF, 8x6 Sadie, MJ 8x12, and 12"DF. Did a comparison on the 7 1/2DF and Sadie with both battery packs, and a comparison of the MJ 8x12 FM, and the Whites 12"DF at 16v. EDIT: I notice I cut off the early portion of the Miner John comparison. Hope you get enough of the sensitivity of that coil. It works very well on my SL. Jim

I have 2 coils on my Tejon. 8x9 conentric I use in high trash areas and parks (same thing) and a 10x12 i use for woods and fields. I got lazy and left the widescan on and hit a local park and came across bottle cap after bottle cap and could not find a good tone break to cut them out without losing too much range. I saved a couple and tucked them in my back yard 6" down and did a quick test. I set my 2nd discrim for break on the widescan and the primary for the concentric and there is a huge jump between them. Both discrim match up on other items such as coins and rings, pull tabs. Note that both coils actually ground balance the same and the widescan can pick up the tiniest pieces of lead and foil. I have found lead pellets from a pellet gun 4-6" down with it. I can also place a cast iron hammer head half over a dime and still hear just the dime though broken signal It's there. So I am really stumped on the bottle caps. Maybe someone here knows why.

I did a coil test some time ago using a Tdi Pro OZ, quite a variety of coils involved. Just a bit of information not wanting it to go to waste. The test area was located in the middle of the Golden Triangle in Victoria, Australia. Looking at the images the test site is located on a area that produced large nuggets. Heavily mineralized to give the depth tests some authenticity. Targets were varied as were the coils tested. The Tdi Pro was ground balanced, gain was at 5, conductivity was in ALL, pulse delay was 10. Frequency was set in the middle and the audio was boosted by a Nokia MD-11 external speaker. Only clear repeatable signals were recorded. All targets were buried in the ground sideway from a miners hole, so as not disturb the soil on the surface or above the target. Only the 1 grain ingot and one 0.5 gram gold coin were buried from the surface disturbing the ground. Not sure how useful this is for Tdi SL users, deduct 10% maybe.. Just gives a sense of what is realistic is this one location at that one time with the Pro with the variety of coils available back then. All the best, Karelian

I know everyone probably gets sick of coil questions, but i have another. So the area i have been detecting and finding nuggets in VA was found back in about 2011 by some friends of mine. They hit it hard for a few years till it got to thick to hunt. One of the patches they found at this place was 100s of yards from all other gold finds, and was initially found with a 9X12 nugget finder coil, when they found a 1.5 ounce nugget. The next trip out they used a NF 24X12 coil and found, i think a 3/4 ounce, an ounce piece and hold your breath a 7 ounce lunker at about 30 inches down. But to my surprise that NF24x12 is the biggest coil they used. He has owned a 18inch and 24 inch mono coil as well but never really used them at this site due to EMI issues. Now my understanding is, that a 14 inch round should out punch the NF 24X12 on large targets at depth, and that Detech coils seem to generally less affect by EMI when compared to NF and coiltek coils. However would a 14inch DD coil out punch a 24X12 mono? Please correct me if im wrong. So the question is, is a 14 inch detech mono going to be a better option, or detechs new 15 inch Ultimate DD coil. Which would punch the deepest in fairly hot ground, with a good bit of EMI flying around. Lots of questions as i learn more about the site im detecting. Thanks guys,

COIL SAVERS Hey guys, I just got these in, they are a really simple and worthwhile upgrade The “CoilSaver” washers serve to massively reduce coil ear and coil yoke wear by spacing them from each other to prevent them rubbing together (see photos) These also make your coil tighter on the shaft (no floppy coil) and reduce the chance of snapping your coil ears off as the bolt will not need to be overly tensioned. They come in a pack of eight with two thicknesses so you can mix and match them depending on the wear of your equipment. (Four washers requires per shaft making two full sets Red washer x4 (3mm) Black washer x4 (2mm) These are currently available at www.detect-Ed.com and we do ship international very affordable but our US dealers will surely have them soon 👍

I was curious if anyone has any knowledge on this.I have a older model spectrum that came with a 9.5" coil and I found a 6" deep scan coil.What is the depth difference between the two under the same conditions.By the way I am mostly a coin shooter.Thanks in advance for any information.
