Important Announcement From White's Electronics

The TDI-SL was purely a development for Africa. The intent was a simple AA battery system and sub-$1000 price tag. Some were built and sent to Africa but it didn't catch on, so the SL was released for domestic sales. I argued hard for a sub-$1000 price tag but lost.

If you look at the PCB on the SL you will see some unstuffed parts that were for future development, including auto ground track. But then I got onto truncated half-sine and the performance was so much better that I completely abandoned the TDI platform. The reason half-sine never saw the light of day is because, for 3 years, I was diverted to developing a security walk-thru which, after I finished the project and even built a production line, was canceled. There is more to the walk-thru story I may tell one day; it is probably the key reason White's failed.

 

I am sure Carl that you know I am not knocking the TDI SL directly. I’ve actually been a fan of the machine for what it is, a wonderfully affordable and ergonomic PI that set a benchmark to exceed in my long commentary at the link.

I’m just disappointed that it marked the end instead of a new beginning, and that nothing better ever came from Whites.

That walk through huh? In 2006 when I visited White’s Alan Holcombe gave me the tour. And with some pride showed me the highly secret project they were working on even then... the walk though detector. No doubt hoping to emulate Garrett’s success in that arena. Sorry to hear that it derailed things those of us here would much rather have seen. Half sine was my hope for the Hail Mary pass that would save White’s.

I just received this email! Important Information from White's Electronics June 18, 2020 To our valued

This was very unexpected, I thought they had another 5 years just coasting. White's had a lot of problems, but I gotta say that in all the jobs I've had the past 40 years, the 6 with White's was by fa

There were a lot of problems, starting with the family. They never had a high opinion of engineers and thought they could be easily replaced as needed. And one particular engineer with an outsized ego

Now people spend all their time trying to modify new TDI units to get them to work as well as the very first ones did out of the box in 2008.

Quite a sentence which I guess maybe should have been obvious to me a long time ago but I just never saw it in this light.  And thinking about it, does the reverse process work?  (Surely it's been tried.)  Instead of trying to make the lightweight TDI/SL as powerful as the so-called (original) Pulse Scan TDI, can one make the Pulse Scan TDI lighter, just like you (Steve H.) did with the Garrett ATX --> 'LTX' conversion?  Or am I missing some other advantage of the TDI/SL besides weight?

I know what you meant, I feel much the same way. The SL was supposed to be a re-boot of the TDI effort. The TDI was difficult to manufacture, it had (I recall) 14 trim pots. The SL had 1 trim pot. The SL suffered a slight depth loss but was more stable. The board was designed to be put in either the SL box or the big TDI box with Lithium power. The intent was an upgrade that had both depth and stability. The board also fit the Beachhunter waterproof box and I built protos for this but it was rejected by mgmt. I hinted at this on the forums and eventually someone (Tom?) picked up on it and released it. There were also extra components on the board to implement ground tracking and a couple of other features. So there was a plan, it just didn't have priority. And the retirement of Dan Geyer left me as the only guy who could (or would) work on it.

The original TDI had a larger board, bigger battery, not a lot of excess really like the ATX. Whites did a good job of making it about as light as it could be so a lot of effort would not gain many ounces. Best bet was to just hip or chest mount it, as it was made to do out of the box.

What I really wanted was a TDI in MX Sport housing. That would have taken the wind out of the Impulse AQ sails to some degree

Hey guys,

I just joined the group, after hearing about this on facebook.  I'm in the UK and I've been a White's user for 20 years.  I can't get any answers from the UK.  My V3i is in for repair which has been up there since before lockdown started (end of March in the UK) 

Does anyone know if I'll be able to get my V3i back or has White's UK pulled the shutters down as well?  I was thinking if the USA can't supply the UK with Detectors, does that mean they wont be able to get parts too?

Thanks anyone who can shed any light

      Hello all, I just signed up!
      Does anyone know what happened to the UKGPA?
      I was a member and I met up with a few from there on a gold panning trip about 3-4 years ago. Thought I'd like to get back into it and have another go, but I can no longer find their website and no trace of them on the internet!
      Think it was Dave and Julie running it, if I remember rightly?
      Would be great to know if they are still around? any info would be greatly appreciated.
      Many thanks!

      As many of you have no doubt heard, the COVID19 situation in El Paso is pretty serious. I posted a while ago information I got from them that they were busy working and shipping product (not so many AQ’s - but). Well, I just had a chance to talk to my main contact in Sales Management at FTP and I think it is useful to share the general message I got. She explained to me that the (new) facility at FTP has advanced air circulation and filtration systems - that all personnel have been provided with highly effective face masks and that workstations and all other aspects of the internal organization of where people work and how they interact with each other have been carefully arranged to absolutely minimize the chance of infection. Her general comment was - the time we spend at work is the safest part of our days. Tom (the President) is deeply involved in making this a safe workplace and has spared no expense in doing so.

      There is a little coin shop next town over from me that used to be a Whites dealer and now has a big Garrett Sign out front. Will stop in and see what they have for inventory. Seems Garrett is using some of the original Whites dealers for distribution. Nice to see the dealers still offer equipment and not disbanding local sales. Good to be able to see new units in hand rather than just online pictures and videos.

      I spoke with Todd Marshall today and he just picked up ALL the left over parts from White's.  He said to give him about 3 weeks to sort it all out before calling for availability.

      I am hesitant to ask about another detecting forum, so I hope it is OK, but is anyone else having trouble getting TNet to load??
