Why Is Everyone Wanting To Jackup The Voltage On Some White’s

Recommended Posts

 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.

There is no benefit to doing so on a VLF because they are all voltage regulated internally. A PI detector is a different beast, and in general more power means more depth, and many PI models are not voltage regulated. Too much power can of course blow the circuit.

The TDI series is odd in that the early models were more powerful and newer models less powerful. The original TDI Pro used a 16V battery pack but White’s went to 12V with the TDI SL, mostly to allow for use of the existing AA power pack scheme, which avoids shipping issues with the old Li-Ion pack that White’s was using. So some people are boosting the voltage back up to gain that little edge that was lost by the move to 12V.

Great explanation Steve. The TDI SL recently released (2018?) special edition was a really fun and comfortable detector to swing since it was so lightweight. I would have definitely kept the one I had for awhile if it wasn't so gutless power-wise. I spent most of my time in the gold fields wondering why it was so quiet. I went behind it with another manufacturers PI made in (2003!!!!!!) with a similar sized coil, basic settings and a 16 year old battery and found out why.............

So does this mean without the higher voltage, I'm missing gold?

Thanks!

You're always missing gold, your detector and skill set determine how much.  Nobody gets it all :laugh: is the fancy new TDI High Q still using the lower voltage battery combination? you would think Whites would get the hint with all the battery mods going on.

Look at it this way.

 My clothes dryer if I set it on medium the heating element will last lots longer. If I keep it on high like I did when I first get it,it don’t last near as long.

 I would say this holds true with a detector. With lower voltage it is less likely to go out before the warranty runs out and it sounds off if the nugget is big enough. White’s didn’t give you the weight of the nugget you could detect but it just would.

 So maybe White’s is trying to make a better coil so they can still keep the voltage as before.

 Please correct me on anything if I’m wrong.

I know that phrunt.  😛

Yes, they're still providing the 12 volt rechargeable and 8-cell flat pack.  I'm guessing because they also use them in other machines, they don't want to up the voltage for fear of someone slipping it in to a GMT, Spectra, MXT, etc.

I found some rechargeable Lithium Ion AAs in 3.7 volts but I doubt if it could handle 29.6.  Too bad they don't make any (AA) in 2-volt.

Thanks!

Hi Walt,

All I can say is that I was hunting a patch with my Equinox 6" coil for the shallow to 6" targets (found a few small nuggets and lots of other ferrous and non ferrous targets and I dug everything) and was using my new TDI SL Special Edition with the 8X12 Miner John folded mono for the deeper stuff. I just happened to have my ancient GP 3500 (which was way past its sell by date) for a backup. I detected the patch with the TDI SL and got no hits. It was operating properly with a fully charged battery pack. I checked the same patch with the GP 3500 with the 11" Commander Mono and it located several  small ( 1 to 2 gram) ferrous and non-ferrous targets in the 11" range. This was in bad mineralized dirt. Otherwise the Nox could have hit those targets with the 11" coil and the TDI SL theoretically should have hit them too.

I am going back to the TDI SL due to weight issues (and my older age) so I too will be doing a battery mod and will mostly use my Nugget Finder coils for prospecting and just use the Miner Johns for beach work.

Depends what the components are rated for, there will be tolerance too so they can safely handle more than they're rated for but that's when you're pushing the limits and may possibly shorten the life.   If they used the same components now as when it was higher voltage then it really makes no difference if you run the higher voltage to component life.

Hello everyone, I emailed whites about the voltage on the TDI SL. I asked if it was okay to use Energizer Ultimate Lithiums for a voltage of 14.48v. Here's what he said below.

      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!

      Not trying to clog up the forum with ebay item(s), but this looks like a hard-to-find item someone here might want:
      ebay.com/itm/18-Cannon-Coil-For-Whites-TDI-Metal-Detector-/2
      Never seen one of these myself and have never heard of this company (if 'Cannon' is actually a company name -- maybe it's not).  Says 17 microsecond or longer delay is recommended, which takes it out of my wheelhouse since my TDI/SPP is locked at 10 us.

      Have a mine lab gpx 5000 and ordered a whites tdi sl for a backup unit a friend told me the gpx coils will work on the tdi?? But it’s not here yet to see if they will even plug in to the whites , so what’s the truth ??? Thanks

      Which do you think will hit deeper on wet sand?  I'd prefer a TDIBH over a DF but I'm budget limited.

      I've had this coil for quite some time, but it was packed away and forgotten. It was purchased for A$60 because I was intrigued.
      It is the anti-interference version. Measures 12 x 4 and uses the MInelab lower rod.
      Weight is decent, build quality is good. Performance in the field still remains a mystery as I've yet to use it. I gave it a quick air test just to see how it behaved on the Tdi Pro.
      This version has a hot spot in the centre of the coil which appears very sensitive to small targets at shallow depth. Seems to hit fairly well at shallow depths but doesn't have much punch for the deeper targets. Test garden results on coins would give real world depth on coins between a solid hit around 15cm or 6 inches and fading fast past 20cm or 8 inches. 
      Useless air test with ground balance off, gain at max, in ALL, frequency in the middle, pulse delay at 10.
      1 grain was               7cm
      .5 gram gold coin  16cm
      1/2 Sovereign         23cm
      Us Quarter              23cm
      Aussie Penny         25cm
      Whites Buckle        33cm
      So in summary it hits hard on small and shallow targets, the centre of the coil is a hot spot for sure.. Fades fast as depth increases, the big Whites buckle just managed 13 inches.
      Since I managed max gain on the Tdi Pro in an EMI hot zone, the Anti-interference feature seems to work ok.. One of the things I like about the Tdi machines is the ability to plug in all sorts of coils, never know if you don't have a go..  My Tdi SL is highly resistance to EMI and the Pro less so but still very good. This coil could make more sense mounted on a Minelab around electric fences and mobile phone towers.. etc.
      All the best,
      Karelian
