This article is intended to try to help someone who is breaking into gold detecting and using a pulse induction (PI) detector.
The Winning Hand
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.

A Gold Mine on a Washington Beach?
Bela and Barbara Kovacs began prospecting for gold about seven years ago as a family orientated outdoors activity. A welder by trade and lured by the simple fact that beach sands can contain small bits of precious metals, Bela decided a few years ago to build a sand sucking contraption that can sift the shoreline for anything worth keeping.
