The Original Gold Master (Nugget detector) was black and did come out about 1990. It then became the Gold Master V-Sat (Variable - Self Adjusting Threshold), Next version was the GM3 with it's Iron ID meter and the latest version is the GMT (Gold Master Tracking) which has the ability to automatically track and adjust itself to ground minerals. The previous GM models only had manual ground balancing. Hope this helps.

Thanks Tom. I was referring to the GMT that featured "Grab" as well
as Automatic Ground Balancing and Tracking; and also sported a
"probability of iron" feature designed to follow stringers of black
(magnetite) sand that could also be associated with float gold.

Float gold often isn't related to the location of heavy black sand. Black sand rarely floats in the water column. It's granular shape prevents that. Float gold, on the other hand, can be carried well beyond the point where the heavy sand drops out. That's due to the flat shape of float, and often flour, gold. Often float gold is found in paystreaks right in the lighter sand..

Parrott, The answer to your question is No.

Hello parrot,

As Tom Slick mentioned, the Goldmaster is a series of progressively improved and renamed nugget detectors. The one you are referring to, the GMT (E Series) is the currently produced version. It was introduced, I believe, aroung 2000, give or take. It operates at 48 (khz), pretty hot on small gold. It has a very good feature set, many of which you mention. It is still a top notch gold nugget detector!
