  1. Speaking of PI detectors. Now that Garrett has aquired White's. How about a multi frequency Whites TDI ??? 98 frequencies from the Infinium. Added to the Whites TDI with it's incredible ground tracking and ground balance. That sounds interesting !
  2. Is the main difference between the TDI Pro and SL is gb course and fine adjustments? Is there any power difference between the models? An old friend might be selling his TDI and I believe it is one of the older Pro's and I might snag it. Also what 3rd party coils work with them?
  3. 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 e
  4. Looking for advice on a small elliptical coil purchase for a TDI Pro. As someone pointed out in the Classified section Serious Detecting is having a clearance sale. Looking at the Coiltek 10 x 5 Joey Mono, and the Whites 7.5 x 12 TDI HI-Q Dual Field. See lots of good reviews for the Joey, but not much is posted on the HI-Q. I guess that initially the HI-Q was only available as part of a TDI-SL package and some were hoping that it would be available separately in the future. It appears that when it became available on its own that it was possibly misleadingly labeled as for MX series detectors,
  5. I currently use a Equinox 800 and I consider myself to know absolutely everything about it. There really isnt anything that anyone can tell me about that machine that i havent mastered and completely already know. Its probably the most simple machine to use on the planet. I understand all the settings and I even know how to exploit the machine to get the results that i want when i want and i know how to get the maximum depth possible on the machine. I can even get a 22 inch air test on a silver quarter. Not too many people know how to do that and it is very relevant when you hunt in places wit
  6. Hey All, Measured White's TDI SL factory battery packs and discovered the following differences. NiMh Battery - HD #802-5321, 2200 mAh. After full a charge, one day later..........................................10.99 VDC AA Battery Holder - #802-7150, 8 cell. With Nuon Industrial Alkaline from White's Factory............12.94 VDC With Member's Mark Alkaline from Sam's Club...................12.96 VDC With Energizer Ultimate Lithium...........................................14.46 VDC Was very surprised that with Alkaline batteries, the t
  7. hello , my wiring go out of my plug and i need a picture or resistance test for, pin out connector , one red with a shield and one clear wire with one shield, the connector have 5 pins but one pin have no seen wire one it, thanks Yves
  8. I finished my channel's intro footage, squeezing some of the last finds in less than two minutes... Hope you enjoy the atmosphere 🙃. Will be difficult to keep it updated constantly with all the work I'm next to start on dryland for water sessions improvement, but keep an eye on my diary now and then🔥 https://youtu.be/1kyGlM9-_do
  9. Hi I have a question regarding all the talk regarding ramping up the amps volts etc on the tdi sl wouldn't good batteries like 8 x energizer lithium batteries add up to 14 volts rather than trying to squeeze an extra battery in there or striping the guts out of the battery pack to put in 4 18500? What about 4 x 14500 which for memory are the same width maybe a tad longer they add up to 15 volts plus I'm not sure any thoughts
  10. A year full of distractions, so yes I kind of did forget about this project. All parts had been ordered and arrived in good time. Assembly to follow in the next few days... with photographs and a performance test on the modified Pro I still have.. I'll take it steady and do it right, get the soldering tidy and follow the plan..
  11. I need to have my coil replaced on my TDI BH Whites service center is not sure they have one at the moment. My Question is what are the pros and cons of putting a 12 inch Aussie Mono coil on. Not for diving just waist deep wading, also does anyone know if the mono will float like the yellow dual field? I am not looking to find small bits of gold, mostly coins and ring size targets on the Northeast beaches. Thanks Jim
  12. Hi, there. I was using my TDI BH for almost two years now. It worked great till the las week then I noticed an important sensitivity drop. In other words, the detector switches on and work as usual, but no matter what I do, I am getting less depth on my targets. Just to give you some numbers. My test target is a nickel coin which I was detecting from 27 cm a least (10us, gain full, gb off). Now, under the same conditions I can detect the same coin at 10-12 cm only. It is not the matter of the battery, as I have tested it with different batteries I have laying around. The TD
  13. I promised myself to go out and test the changes I made on the Tdi Beachhunter ... In the end, all works properly and I'm a bit proud of what I've done thanks to some help I received here on the forum... Last night, however, I got my hands on the scuba harness and made one of the most serious miscalculations ... Removing a lot of weight to be free to reach the beach without paying the price of pain after the fatigue ... I had in mind some splendid video on sidemount setup, which intrigued me to try in terms of set-up ... The result was crap to say the least ...Sh...happens... Not only
  14. I have decided to finally swap out my big 12” Dual field coil on my TDIBH for something smaller. The purpose is to use in the water. I have some pros and cons with each model so feel free to add any ideas you have. Coiltek Platypus 12x8. Waterproof, epoxy filled. Maybe too long on the 12” side which sees the most water resistance Detech 8” Mono. Foam filled so more buoyant but not too worried as 2/3 the size of the Dual Field coil. Good size. Waterproof. Garrett 8” Mono coil. Waterproof, epoxy filled. Good size. Suitable for lower delays? Garrett coil Coiltek c
  15. this machine is new have used it for about a month never droped it or abused it , this is what is happeneing when i turn it on ,it starts overloading and moaning but only in the All or high position if i turn to low its a quite as a mouse turn it to all and it starts moaning and will not stop , any ideas?
  16. A friend traded me an old Tdi Sl for my old Canon DSLR with a couple lenses. The camera was old but still worked well and perhaps worth a couple hundred at most, so I threw in a telephoto lens and we had a deal. I got a dead or dying Tdi Sl in exchange. The machine would power on etc everything seems to work except it will not ground balance and sensitivity was way down to almost nothing. Ok so not dead but way out of sorts at least. The previous owner has moved on after having done something to the machine. Yes he had opened it up and poked about and tried to make adjustments or something to
  17. I took my Excalibur out yesterday water hunting to an area I thought might hold some loot.....I was rewarded with a very nice Platinum ring. The area was inundated with old bottlecaps and even though the Excal was nulling them out perfectly, it was hard going and required a good deal of patience. Because of this, I have decided to keep the TDIBH strictly for beach work as using a PI in this area would have made me quit in disgust. The detector has been reassembled back to the original Coil as I was planning on swapping out for a smaller coil for the water. I feel too much time would
  18. Hi! after a year of snorkeling with TDI BH I concluded that I can clearly note the sensitivity goes down ones the voltage of my battery pack goes down. Other conclusion was that even at 12.6V the TDI BH is noisy underwater at maximum settings: it reacts to the waves. Thus at the moment I really prefer to have just a stabilized battery pack. For my experiment I took a couple of 21700 5aH Li-Ion cells and a dc-dc booster board. the plan is to get "one hunt" battery pack.
  19. I see so many people wanting to up the voltage. I know by doing so also improves sensitivity and overall performance. Maybe someone can tell me why didn’t White’s do the same. My thinking is less load on the electronics makes the detector last longer. At the same time the detector will have a better chance of making it through the warranty . Here’s another can of worms I’ve opened up. Chuck
  20. I was on my way back from a detecting trip near Winnemucca. I stopped in at Armadillo in Grants Pass, Oregon and saw this hanging on the wall. Apparently, there are only three in existence. This one belongs to Sam. From what I understand, she received this for being the top salesperson in the company with this model. I think this would have been a way better color than the original black!
  21. In a previous post few years ago, I read where a forum member I think it was REG was stating he had given Whites the information on how to do several modifications to improve performance. I think this was about Dec. 11, 2016 1. build battery pack using Panasonic 3400mah. 2. modify filters to allow for faster swing speed. (reduce value of c20 and c21 from 0.47uf to 0.22uf). and a few other changes. After that said, the TDI SL I just purchased shows it is a 2015 model. Am I correct in thinking these mods. were not done at factory? I am going to open up my unit and check c20 an
  22. On the TDI Pro the upper handle was a bolt on assembly with separate part numbers The prototype models has a straight shaft, and the production models an S shaft. In either case you could remove the handle via four bolts to hip or chest mount the control box. Since the production models went S shaft, there were aftermarket straight shafts. Here is the Anderson aftermarket straight shaft for the TDI Pro: https://www.seriousdetecting.com/product/anderson-whites-tdi-metal-detector-black-carbon-fiber-shaft/ Does anyone have any part numbers for the original TDI upper h
  23. Started like a boring session this morning... Everything ready to do another underwater footage of mine but as usual, almost nothing can be done right as we want. Camera's battery dried up after 3 hours...Coins and garbage at some serious depth with the Tdi...After five hours, leaving the beach really destroyed, the last signal heard with died battery on the machine was the wedding band buried in few sand but too old to be a fresh drop.🤔...Clueless find even today.. So this is the only picture to show...
  24. I squeezed in few minutes a 4 hours session of today... Enjoy with me the two rings I found...
  25. I'm so bored of my 12" dual field coil on my TDI bH that I now want to change the coil with an 8" mono. I know this can be a stupid question, but I try to ask... Can a Garrett Sea Hunter coil be adapted on the TDI? I need an open design coil to hunt underwater... The only other option is a Detech closed 8" mono...Which will float even more than now cause of the tdi control box balloon like buoyancy... Shoot your answers please mates!!!
