GOLD behaves as it has for the past 100 years!

The process of using the force of gravity combined with ANY combination of moss, carpet, and/or matting has always been known to work to one degree or another.
Marketing has driven the technology;
The best way to sell something is to incorporate the word "NEW Technology". There really is NO NEW technology. The technology has not changed. Oh... lookie here... Riffles in a GOLD PAN!

Magneto ignition systems;
I bought a NEW Generac AC Generator for the mine a few years ago. It has a magneto ignition system. Magneto ignition systems have been used in airplanes from the beginning and into current production airplane engines.
Why?
Because they are simple and reliable!
Remote prospectors learn ONE LESSON early in their prospecting experience... Keep it simple. Keeping things simple helps to improve reliability!
