  1. A long time ago I had the entire world supply of a certain “space rated” transistor (not an IC or a chip - just a stinking transistor) in my bottom right-hand desk drawer. I was a contracts manager at Allied Signal (now Honeywell since they bought Honeywell) and we had a product which used this component on a launch vehicle. We got an order for the product from a customer and suddenly the you know what hit that rotating thing. The parts in my drawer were absolutely required and WAY no longer available. Only problem was the “traceability” could not be documented. A gap in the paperwork made them unusable. A couple of weeks of furious phone calls (this was a while back!) and I scored the precious bit of paper. Got a nice raise that year.
  2. There is no evidence that they ever stopped doing custom manufacturing for OEM’s and others. In addition, they have a robust and popular line of utility and leak detectors.
  3. Mass production of electronic circuits and devices is the real root of the whole enterprise. I believe that Tom Walsh (the CEO) manufactured PCB’s and small integrated devices for the automotive market at a Maquiladora in Juarez for years before he saw the opportunity in metal detectors. Others were building low volume machines with lots of hand labor. Tom bought a couple of defunct brands, Teknetics and Bounty Hunter and used their designs to bring out a line of mass produced machines. He then hired Dave Johnson to be chief designer and shortly thereafter FT acquired Fisher which was teetering on the bank of extinction due to terrible management and a series of ”Strike” machines which sold poorly. With a new term of engineers, including Dave Johnson, they produced a full line of Fisher and Teknetics products as well as numerous Bounty Hunter models. Carl Moreland was hired in early 2014 - after he left Whites. Carl saw Alexandre Tartar’s posts on Carl’s Geotech website and contacted him. The end result was FT acquiring the Manta project and hiring the “Euroteam”.
  4. Here’s a little something LE.JAG posted on another forum recently - along the same lines... a scoop for the forum the latest changes now allow detect a 24 carat ring weighing less than 5 gr (no ring 24k heavier to test ...) under a big nail / or several small nails if you have a ring 24k try with your detectors it's impossible / even tdi (modif Reg Sniff) can not do it (22K is its limit ) it will be a very specific setting that I would explain in video this extraordinary feat? detect the 24k under the iron gives you an idea of the level of separation, gold / iron”
  5. My bad, I screwed up the date on my post above. I have been “leaking” about the manta since June 2017, not 2918. http://metaldetectingforum.com/showthread.php?t=248668
  6. It’s mainly me who has teased everyone by posting stuff about this since June 2018. Fisher showed a prototype at one show in Germany this last winter. It’s a totally new thing for them. The entire design team was the subject of an “acquihire” of Alexandre Tartar and his fellow “Manta” team members. It is by all accounts a more complex and tighter tolerance device that First Texas is used to producing. That and the likelihood that a dedicated beach PI will be a “niche” machine and therefore not a mass market seller, and the likely high production cost - make it understandable why they are proceeding very carefully.
  7. The latest posts by LE.JAG have indicated that the “hole” at the upper end has been steadily nibbled away at - and now lies “above” even massive rings and 22kt gold. 24k is likely still “in the hole” - which is to say, excluded along with ferrous targets, silver and other high conductors when the discrimination function is enabled.
  8. Yes, it apparently expired the 12th of October!
  9. Nice summary Steve. I also agree about hand chafing on the underside of the control box/top of the grip - That’s the main reason I got rid of my 600. I am curious about the near universal preference of water hunters for straight shafts. I never surf hunted with anything but a Whites DFPI, so I have no data as to why that seems to be a fact.
  10. I guess the old saying is LITERALLY TRUE Different strokes for different folks!
  11. I don’t disagree with your summary - guess I don’t like being accused of “bringing it up a lot”- I just edited my above post to document how often I have done so on this forum - (unless I missed something) Sounds like I have some axe to grind. I don’t. The Nox is an amazing machine which has revolutionized the detector marketplace. I have had two of them. It has lousy ergonomics and it’s light weight is its redeeming feature. One wonders however if the well documented problems with the shafts and coil ear breakage don’t have something to do with physics rearing its ugly head.
  12. Glad it suits you. You said that the Deus pointed the way to CPOS detectors. My point is that the Deus rod is WAY more than a stick. As far as it being something that “you bring up a lot Rick” - you must be sensitive to this, because I just dis a quick search of all my posts on this forum back to when I got my first Nox800 and then showed it to Dave Johnson. There were two I could find... May 18 2018... The ergonomic argument against the straight shaft is based on the fact that if you look at a straight shaft detector set-up from the side, then draw a line from the inside bottom of the arm cup through the center of the handle, that line projects out to a point well above (in front of) the junction of the shaft with the coil. This results in torque (twisting) when you initiate or reverse a swing with the coil. This force must be resisted by your body. It also introduces twisting strains on the handle mount and the joints in the rod. Here’s a quick and dirty sketch. (Same sketch attached) June 9 2018...”There’s an excellent reason why detectors are laid out the way the vast majority of them are - straight shafts mean the the handgrip twists at each swing reversal. I guess that’s “a lot”
  13. It’s not the “cell phone” that’s the problem - it’s the dumb stick. The Deus rod is strong, lightweight and ergonomic. All the various “cell phone on a stick” designs suffer from the same terrible ergonomics. Every swing reversal causes rotation about the axis of the shaft. Look at the picture above of the Deus. The axis of force goes from the middle of the arm cuff, through the middle of the grip to the center of the coil. On almost all of the “CPOS” (cell phone on stick) designs that line reaches the ground well in front of the front edge of the coil. Hence the torque around the axis of force with each swing initiation/reversal. It’s not me saying that. In 2018 I showed my new Nox to Dave Johnson in El Paso. While I was 6 feet away and before he touched it, he said - “Let me show you how the ergonomics are flawed”
  14. OP - that’s how we get $10k toilet seats. No company can afford to spend that kind of money testing every unit of a sub $1k detector. You have to just design it right to start with, then qualify a production process which yields six sigma quality units.
  15. I stumbled across this article while trying to find data on how high the prices of T2’s and GPX’s got during the big African gold detector rush of the period around 2010. Pretty fascinating stuff if you can digest some “high falutin’“ anthropological jargon. She also published a book on the subject - 2nd link. https://www.worldcat.org/title/who-knows-tomorrow-uncertainty-in-north-eastern-sudan/oclc/1020656228
