Lisle, Ill., Feb. 10, 2015Minelab, the world leader in providing metal detecting technologies for consumer, humanitarian demining and military needs, today announced that gold prospector Steve Herschbach of Reno, Nev., has uncovered a 6.5-ounce solid gold nugget, an exceptionally rare find in the United States, during a 30-day expedition in Chicken, Alaska. Along with the 6.5-ounce nugget, Herschbach uncovered a total of 12.3 ounces of gold.

Discovered on Jake Wade Creek in the Forty mile country, Herschbach’s treasure hoard includes the monumental 6.5-ounce solid gold nugget, a 2.5-gram cornflake, 3.4-gram solid gold nugget, a 6.1-gram gold marble, a quarter-sized 6.87-pennyweight and a 1.3-pennyweight nugget.

“I had barely gotten started when the detector gave me a descending, low-tone boomer signal. After digging through the ground at the pinpointed location, I stood there looking at 6.5-ounces of solid gold in my hand!” said Herschbach. “There is no denying the horsepower advantage of the GPX 5000, and the success of this trip reiterates that there is no other detector like a Minelab detector.”

“We are thrilled that the GPX 5000 was the key tool in Steve’s discoveries,” said Gary Schafer, General Manager of Worldwide Consumer Markets. “This model’s incredible flexibility, audio response and keen ability to pinpoint whether a find is gold or trash, makes the GPX 5000 one of the top-shelf detectors in the market.”

The smooth and quiet Minelab GPX 5000 gold detector features Minelab’s exclusive technologies including:

  • Multi Period Sensing (MPS) to remove ground signal from even the most highly mineralized ground while still being sensitive to both small and deep gold pieces.
  • Dual Voltage Technology (DVT) to increase the amount of power transmitted into the ground increasing detection depth and sensitivity.
  • Smart Electronic Timing Alignment (SETA) to improve detector performance through complete removal of noise signals in the ground.

Its significant depth advantage allows detectorists to uncover from sub-gram nuggets to elusive “retirement nuggets” to all sizes in between.
