Blast To The Past With White’s

I had one of those also, but was too stupid at the time to realize the power I had in my hands with the very first ground balancing metal detector. Ground Exclusion Balance (G.E.B.) was our introduction to VLF ground balancing technology. The funny part is all I focused on was the Coinmaster V Supreme would find nails per swing that my earlier T/R models ignored entirely. If I had caught on to what potential the machine had for nugget detecting things might have been a little different, but I let it go way too soon.

Here is an ad blurb from the 1976 catalog, plus a picture below of a little later model Coinmaster 5/DB (crude discrimination added) at the White's factory. Click on photos for larger versions.


I'm still trying to figure out when the Coinmaster V Supreme first came out. GEB was top dog then :laugh:. But it cut right through mineralized ground and had some pretty good depth, if you like digging those whisper targets. Nails could be figured out somewhat if you did a 90 degree turn. They would double bleep if they were close enough. Not 100 percent effective though. We dug a LOT of holes back then. I had the 5DB also (or was there a 5000D model?)..... the worst machine ever. Total loss of depth. I heard the later model Di's were good but I left whites for a while, and only returned when The Eagle and Eagle Spectrum came out. That Spectrum was another great machine from them. The older units weighed a ton and changing them 14 AA batteries hurt the wallet! The word ergonomics wasn't even invented then :wink:

I think the straight up Coinmaster V Supreme with no discrimination came out in 1975, but was very quickly replaced by the Coinmaster 5/D, which tacked on a very basic T/R discrimination circuit that did not go a third the depth of the machine in all metal. No good on the deep stuff. This ad copy is from the 1976 White’s catalog. Unfortunately I have no 1975 catalog to refer to.

The Coinmaster 5/DB if I recall correctly added an early version S.A.T. (self Adjusting Threshold) before it was actually called that. And yes there was a 5000D also, which is about when they were slimming down the metal boxes to smaller than mailbox dimensions.

Not only did ergonomics not exist then, but these machines were “anti-ergonomic”!

      I came across an old letter about metal detector I sent to a mate,
      "My first detector was a hired Whites 5000. I got a new Garrett Deepseeker for the September school holidays 1980, for my wife. It was too hot (weather) in wedderburn for her during the first summer and I ended up with it. Got her a whites coinmaster 6000 for the next trip as it had motion discrimination and was easier and quieter in the hot ground. It took a while for me find any detector that exceeded the Garretts. However I found that my White goldmaster (1986 ) was much easier to use in the Victorian gold fields. I made a PI detector with a hand made Teflon coated wire coil before 1986 that would go deeper than the Garrett Deepseeker but was too slow to use in the field and I did not like the sound of the clicking sensor. .........."
      Do you have fond memories of your first one (detectors that is 😀)

      On my FB a few weeks ago I posted a photo of a thin metal tin rectangular in shape that had Chinese writing on it. Yes I know it is an opium tin, but what does the symbols say? Found these 3 at an old mining site with Equinox. Thanks for your help.

      The ads came from mags dating back to 66. I can say I remember them all. Just maybe you remember some if not all.

      Introducing the worlds first Equinox, the Equinox 100 was shown at the West Coast Computer Faire c. 1977. 
       Wow this things been in development for like 40 years!
