  1. An acquaintance has asked if I'd help him find some shotguns he buried several years ago. They are wrapped in oilcloths, sealed in PVC pipes (~3 in = 7.5 cm diameter) and buried about 20 inches (half meter) deep according to him. He says he can show me the approximate location within about 10 m. If all this is accurate it seems like an easy task.... Then again, he also said someone in his family (without him being present) tried to find them with a detector and couldn't. That could be due to a lot of reasons as I'm sure you are already thinking, but my concern is that they may be buried more deeply than he remembers. Which of the following would be your first choice? 1) TDI/SPP with 12 in round mono and 16 V battery pack. 2) X-Terra 705 w/15 in Coiltek 3kHz. 3) Gold Bug Pro (19 kHz) w/15 in Nel Attack. 4) F75 black (13 kHz) w/11x7 in^2 coil operating in cache process. Assuming he has the time and patience I'm going to have all four with me to do a comparison, but I'd like to start with the one that gives me the best chance. Your advice is appreciated.
  2. ran into an old friend yesterday he asked what I had been up to told him I do a lot of metal detecting and he said he has a whites TDI that he says he has used vary little he ask me if I would be interested in purchasing it from him because he says it just sits there collecting dust I asked him how much he wanted site unseen and he told me he would let me have it for $150 he says he has had it since 2010 said he purchased it new,I do not know anything about whites to know if thats a good price for a used one or not. is there different versions of that particular detector that I should be aware of when I go look at his or is there only one version are there any potential issues the TDI had from that year that I should be aware of also i am supposed to go look at it on Monday so thats why I am asking don't want to waist my time if its not worth it,its a long drive so just trying to decide whether to take the drive or not Thanks for reading
  3. Here is the blurb from the White’s website: The TDI SL Metal Detector has pulse induction power that provides unbeatable depth and sensitivity in its price range. And now the deal is even better. More than a new paint job, this Special Edition features key changes to the TDI platform aimed at serious prospectors. First and foremost, this detector ships with an 8 x 12″ Miner John Designs Folded Mono search coil. This choice was made to give gold prospectors better depth on large nuggets, but also increased sensitivity to small specimen gold that other pulse machines might miss. We also swapped the intermediate and lower shafts to create a streamlined “straight shaft” configuration preferred by gold hunters. Finally, to top it all off we revamped the control box with a desert tan paint scheme ideal for hot environments. This package is offered for a limited time and at a discounted price. And best of all the detector and coil are Made in America. The rechargeable NIMH battery lasts up to 6 hours, and a backup AA battery back will power all-day exploration. At a weight of only 3.3 lbs, and rugged metal construction, this Special Edition TDI SL is ready for serious prospecting. Are you? If you already have the TDI and just want to buy this awesome coil, please visit Miner John’s website. Download Product Manual SKU: 800-0332-MJD MSRP $1099.95
  4. Have been given a TDI SL and I'm not that keen on the 11' spider mono coil attached . ( mainly the sticks and debris that get caught up ) Detecting in heavily mineralised ground in the Golden Triangle Australia and it was suggested that I purchase a used 12"/14" Coiltek Goldstalker mono round . Any thought on that please.!!!!! I run a SDC2300 and soooon a Equinox ????? . The TDI will just give me a little extra depth to go wandering away from the diggings . Thanks in advance for any suggestions . Cheers goldrat
  5. Hoy he estado probando mi nueva bobina para tdi y me ha gustado cómo funciona en la playa. Va muy estable y lo noto más sensible que el dual. Hoy no ha habido suerte y no he traído oro, la próxima vez será "Today I have been testing my new coil for tdi and I liked how it works on the beach. It goes very stable and I notice it more sensitive than the dual. Today there has been no luck and I have not brought gold, next time it will be"
  6. G. B. TDI SL

    Cuando uso el tdi sl en la playa, puedo usarlo con el GB apagado sin problemas, incluso poniendo la bobina en el agua. Pero sin embargo en el campo no puedo. Tengo que equilibrar la tierra. ¿Cual es la razon?
  7. https://www.ebay.com/itm/Whites-TDI-Pro-Pulsescan-metal-detector-with-12-waterproof-spider-coil/302555482387?hash=item4671b64913:g:7goAAOSwDfJaJGPg $1500 for the standard(?) package. I think that is what the last full retail price was before they were discontinued. To be fair, sometimes (often?) Ebay auctions turn into grudge-match ego infused bidding wars. (This happens in face-to-face auctions, too.) My rule-of-thumb is to use the 3rd highest bidder's final bid to determine value in highly contested auctions. That price here is $1255.55. I guess White's just wasn't selling enough of these or they wouldn't have ended production. The TDI-Pro certainly has its diehard followers/supporters/users, but I guess you could say that about most decent products.
  8. Bigfoot For Tdi??

  9. Silver

    You might be thinking, what is the big deal, but... This dime came from a hunted out site using the TDI and the OZ 12" coil. The coil was loaned to me by GB_Amateur aka Steve. I have been hunting this small area, maybe 50' x 100' for over 2 years. This site has given up many silver and copper coins. The site has also been hunted by two of my hunting buddies using the CTX 3030, Whites DFX, Fisher F75 and of course the TDI. The OZ coil is super deep in this area and extremely stable. I also dug over 10 nice large nails prior to finding this dime. I must admit I had been purposely looking for only the deeper sounding targets and ignoring the shallow one. I might add one more thing, all the nails sounded about the same, but I dug anyway. On the other hand the dime sounded strange compared to the nails. Can't explain the actual sound, but hope to soon, hear it again. If possible I might try to record the actual audio and post for all to hear. May be a few days before getting to hunt again, weather will turn much colder this weekend. Thanks again Steve.
  10. Over ten years ago I was pushing pretty hard on the idea that high power pulse induction detectors would eventually find use for more than just nugget detecting. Relic hunters in bad ground seemed a particularly obvious situation where PI detectors could pick up where the VLFs left off. Daniel TN just made a great post over at Dankowski’s about the shift from VLF to PI, and how the PI use progressed up the power ladder from Garrett Infinium to White’s TDI to Minelab GPX. I ended up calling this Steve’s Law Of Target Depletion. The basic premise is that if high value targets exist, people will start with discriminating VLF detectors and dig the easy targets. However, knowing good finds remain, over time more trash is dug and more powerful detectors used. As long as any chance of a good find remains, this progression will ultimately deplete a good location of all targets, good and bad. Prospectors see this all the time. A location will start with trash and gold. VLFs cherry pick out the easy stuff. Then the “dig it all” troops go to work. Sooner or later you get to where just finding a target, any target, gets to be a challenge. Yet as long as a single target remains, good finds still might happen. If nothing else the trash can hide good targets lurking below, and so even trash remaining can be a good sign. You can never call a place detected out until no targets at all remain in the ground that can be found. And even then, a newer, more powerful detector may make the place come to life again, at least for a time.
  11. One of our dealers sent me this email today. NO I don't know the guy's name and YES if I find out who it is you can be damn sure I will try and get permission to go detecting with him next time: "My customer, (who would like to remain anonymous) a Southern Oregon Gold Dredger that loves to be out in our mountains all year round. He spends his summer weekends in the water with his dredge. A few years ago, he decided to try his hand at Metal Detecting the ground his has been traipsing over for 25 or 30 years. We discuss his options. He has had an MXT for years, but for Placer Gold it just wasn’t going to avoid the hot rocks and cover the tuff ground that he wants to look in. I sent him out with my demo GMT and my personal TDI SL. Clearly the TDI SL was the right choice for his highly mineralized ground. So the machine was decided. He also wanted the right coil for HIS ground. He works a lot of shallow bedrock, also right on the edge of the creek and up the bank often following bedrock. He decided on the SMALLEST folded mono coil we could find with the elliptical shape. His terrain is tuff, rocks and trees in all the right places / wrong places, depending on if something is found. Fast Forward 2 Years: He has had a very exciting year. Finding the smallest picker first and getting bigger each time. He has purchased a second coil to cover more ground and get the optimal depth. We have also just finished our research for an increased voltage battery for the best performance and longer run time on the bigger coil. Thank you for all your support Please enjoy the pictures of your successful product!"
  12. Well my 8 x 14 coil came yesterday and I got to hunt at an old school yard where coal waste has been discarded for many decades. The coil seemed to run fairly good. Noticed a few things: Actual ground balance was a little higher (tad over 8) than with my other coils. Increasing the delay didn't change the GB as much as my other coils. It was obvious when the GB balance was off by the increased false audio reports. I could actually run gain to 7, but past that the machine would false in this bad ground. With the stock coil I usually settle with gain of 6. Very good coverage. Felt lighter than the 12" stock coil, but I believe the 12" is a deeper running coil, air test might be in order I could actually pinpoint better (off the front end of the coil) than the stock coils. My holes were noticeably smaller due to better target location. Plenty deep enough, I know some may laugh, but I dug beer beaver tails at 6" in this terrible ground. But I was hunting for gold not coins. Looking forward to my next chance after Nate passes by. No gold jewelry found this time.
  13. This guy uses the TDI on beaches and finds a ton of gold... Also, good video si hablan espanol. But he does everything in both ingles and Spanish. I thought it was cool to see a side by side on both the TDI SL and TDI Pro. Sounds like he is switching to just the SL for now. Whaddya guys think?
  14. 14" TDI Coil

    Anyone had experience with this coil?
  15. In my ongoing Quest for that First Elusive nugget i took the TDI SL with a Miner John 5"x9" coil and went to a local gold producing river today. Sorry to say still No Nugget but i got enough fishing lead to cast a few bullets. Some of these were Really small split shot and bird shot so i know i am doing something right. Just got to find a piece of Yellow stuff to put the coil over.
  16. Whites TDI SL

    Gidday guys, i had just bought the new whites tdi sl, i paired it up with the 8" detech coil. These are my first finds with it, i found them within 30 minutes after turning the unit on for the first time. No hot rock found and no ground noise to be heard, first signal to be found was this specie, a nice sweet solid signal, after i moved the litter i scraped away 2 inches to find it, the picture of the larger gold here is what was inside, a 0.61g nugget. Found a few iron target and $2.00, there signals were loud, the iron was very obvious, the coin was a very nice signal, i then found this 0.26g piece, moved the litter and scraped away 4 inches b4 i found it in the hole. The Detech coil runs very quiet and smooth, on this ground, i balanced out at 9 1/2, the gain seemed very happy on 5, all other setting were default. My mate had his gpx4500 running the NF Sadie coil, over the same ground, he was finding all the hot rocks and ground noise, of course he balanced it all out but as he went forward he had to keep balancing out, me, i kept all the tdi settings the same and only ever balanced the once on start up. Its a very quiet and smooth running machine which really impressed my mate with the gpx, i am sorry i dont have a video, i did not prepare myself for the what ifs, next time, i just bought a go pro, so footage of this setup in operation will follow on my next day out. For a budget pi machine under $2000.00 that is a proven gold grabber, i highly recommend this unit with the detech mono.
  17. Hello everybody on the forum, hello Steve! I am a relic and coin hunter in Europe. Among other detectors I have used Minelab pulse machines since 1999, so I have a small arsenal of Coiltek and Detech coils for SD, GP and GPX models. ... and now I have set my mind to owning a White's TDI SL as well. I heard and read that Coiltek and Detech coils for SD, GP and GPX models can also be used on the TDI. Is that true?? I'm looking forward to your answers! Take care and good hunt! Zsolt
  18. Anyone familiar with this coil for the Whites TDI's? I just ordered one from Whites. They have them for sale right now for $35 + shipping so for that price i figured i would try one. If you want one better get it while they last.
  19. Any experiences with the Coiltek Elliptical 10inch x 5inch on the White's TDI?
  20. A few things I've learned about coal waste hunting. I started inquiring about some old locations I hunt. Most of the locations are old, shut down schools where coal was used as a heating source for decades. Before the EPA was birthed most people did what ever pleased them when it came to disposing of waste, regardless of what it was and these old school sites are no exception. The burnt coal waste was spread over many acres of school property which created some extremely harsh ground conditions. Grass and weeds find it hard to get a start and most areas are void of any vegetation. Most of the school grounds look like Martian landscapes with small BB size or smaller pieces of coal waste everywhere. This material attracts to a magnet with little effort and can reduce depth of all VLF detectors by well over half. In fact until recently maximum detection depth was actually 2-3”. Any target deeper would give a solid iron audio report if any sound at all. After many years of hunting these areas, all but completely unsuccessfully, I finally purchase a White’s TDI SL. It turned out the SL opened up these old sites and many nice coins, relics and gold jewelry were unearthed, but not without many trials and numerous adjustments. Case in point: one particular area had been, in my opinion hunted out with many different VLF machines (ranging in cost from $250 - $2000) over a 10 year period and I was certain there were no good targets left. Now I’m going to fast forward 2 years of hunting experience and mention a couple very important and rewarding hunting trips that might help someone. Settings: sensitivity 6, ground balance 7 ½, pulse delay 10 and conductivity set to high and used the stock 12” dual field coil First was an old school site where both coal waste and nails are very abundant. I had been hunting about 15 minutes and all the SL was giving were very short audio reports, which sounded more like chatter or EMI and not targets. This prompted me to increase the time delay to about 15 , which increases the time before a transmitted signal is analyzed, thinking the small pieces of coal waste were the short reports (partial masking) I was hearing. Continued hunting another 5 minutes and noticed the short audio chatter continued but not to the same magnitude. Stopping and increased the delay to around 17 and off I went hunting again. Suddenly I noticed the machine was running very quiet, to quiet. A minute or two later and a very loud low tone, which on the SL means a high conductor, I stopped and reduced the delay to 10 and found my definite answer. The coal waste was causing the ground chatter and false audio reports. Increased the delay back to 17 and recovered a wheat penny around 4” deep. Now to be honest I had to stop for a moment and think about what just happened. Decided to start over I returned to where I began hunting and discovered I had passed right over many good targets. After digging a few more wheat pennies and a silver dime I decided to start checking these targets before digging and discovered if I decreased the delay most of these targets became the short sounding audio reports I had heard earlier. The PI was just the trick to discovering some nice coins deeper than 4” in these barren areas. From this site I learned the time delay helps with eliminating small metallic pieces from interfering with coins and other relics. I must admit, at times, I tend to over think some of my hunting trips but the thought came to mind. What if there was gold jewelry in the area where I was hunting coins (conductivity high)? Yes I could have been hunting with a setting of all but the area is so polluted with targets I chose only high. So another trip to the same site with only two setting changes pulse delay 15 and conductivity set to low. In addition to this I change, I opted for the smaller 7 /12” dual field coil. Again the delay settings helped with the coal waste problem mentioned above and allowed me to hunt with a little sanity. Less than 15 minutes later came my first ring, not gold but gold plated, but that helped motivate me to keep going. Dug a couple beer pull tabs and finally a nice gold class ring came to light. What a very rewarding hunt it turned out to be. Mark Gillespie 2017
  21. White's quietly instituted a summer sale (ends in August) that resulted in some steep price drops for some models. The TDI SL was dropped from MSRP $1299.95 to $1099.95 which in turn created a Minimum Advertised Price (MAP) of only $989. As ground balancing PI (GBPI) detectors go the TDI SL is no powerhouse, but this price reduction puts it firmly in VLF country as far as the hit it will put on your pocketbook. If you have a VLF and places it refuses to work due to intense ground and hot rocks, this presents an affordable potential solution.
  22. Has anyone used them on their TDI and if so, how do they do on Gold? Especially interested in the larger coils like the 12"x15" mono for the GPX. Will it work on the TDI ? Would it be a good choice for covering a lot of ground prospecting for nuggets and will it find the smaller ones still? Would it be any better than the stock 12" dual field? Any experiences and help appreciated.
  23. Need mods done for my tdi. My sister has some property with an old township on it. Would like higher voltage batteries also. Can you put batteries in before mods or after? Thanks strider55
  24. Exciting TDI Discovery

    To start with I must confess and hope the following information doesn't give the wrong impression about the TDI SL. It has a lot of potential, but only in certain locations not loaded with a lot of nails. I started inquiring about some old locations I hunt. Most of the locations are old, shut down schools where coal was used as a heating source for decades. Before the EPA was birthed most people did what ever pleased them when it came to disposing of waste, regardless of what it was and these old school sites are no exception. The burnt coal waste was spread over many acres of school property which created some extremely harsh ground conditions. Grass and weeds find it hard to get a start and most areas are void of any vegetation. Most of the school grounds look like Martian landscapes with small BB size or smaller pieces of coal waste everywhere. This material attracts to a magnet with little effort and can reduce depth of all VLF detectors by well over half. In fact until recently maximum detection depth was actually 2-3”, any target deeper would give a solid iron audio report if any sound at all. After many years of hunting these areas all but completely unsuccessfully I finally purchase a White’s TDI SL. It turned out the SL opened up these old sites and many nice coins and relics were unearthed, but not without many trials and numerous adjustments. Case in point: one particular area had been, in my opinion hunted out with many different VLF machines over a 10 year period and I was certain there were no good targets left. I had been hunting about 15 minutes and all the SL was giving were very short audio reports, which sounded more like chatter or EMI and not targets. This prompted me to increase the time delay to about 15 “which increases the time before a transmitted signal is analyzed” thinking the small pieces of coal waste were the short reports I was hearing.

The PI was just the trick to discovering some nice coins deeper than 4” in these barren areas. I must add the SL is not the best choice to make if there is an over abundance of nails because of the very limited discrimination capabilities of this particular machine. As a final note I must admit this machine has opened up a lot of hunted out harsh ground sites.
  25. I recently added a PI unit to my weapons hoping to get further depth on caches of buried cans and bottles at 3 feet and deeper. I am mostly using the detector only to find the deeply buried pits of ferrous cans/ "trash". I know there is a learning curve to all new equipment but am throwing out some questions here for those who have used the White's SPP. First thing I notice is the detector is very sensitive especially to shallow scatter like concentrations of scattered nails and wire, especially wire in coils or even hangers bent in round loops sound like a much better target. I have read that adding a much larger coil like an SEF style in 20x17 format will eliminate some of the "noise" of semi surface items as well as add a bit of depth. My question is having the SPP without the Pulse Delay setting am I going to have a problem running these coils? I had read elsewhere that guys turn up the Delay setting when using the larger coil and the SPP does not have this ability. My first time out experimenting on finding a large deep target of cans I knew existed I ran the coil that came with the unit and in range on controls suggested in thres and gain. I picked up a number of small sharp high tone signals and dug them just for experience. I came up with bottle caps, loose change, a 2 dollar Mexican coin and a nice men's gold band. But these are not the type of targets I seek and would rather hear the deeper low tones that suggest concentrations of deeper buried metallic objects (trash). I was able to easily find the pit of old cans that were about 3 1/2 feet down but noticed it was very hard to pinpoint the signal and it seemed to overload or max out the detector signal. When switching to OFF on GB and running in an non motion mode I did well but experienced the same overload type effect on deep concentration target. When I turned the GAIN down some it helped with average targets of say 6 pack of cans at 2 foot, but I lost the ability to pick up the deep target. I know I am looking to use machine in ways most are trying to avoid in digging "trash" but just looking for any suggestions on coils and settings that may help with my learning curve. THANKS!
