Gpx5000 first 2 weeks with a PI. Northern California motherlode 38 gram specimen 31.132 grams of gold after specific gravity. I also found a 1.73 gram crystalline chevron nugget. And with the GM1000 I picked up a 1890 silver seated liberty dime. All on a 2 week mining trip in the mountains. I also used the minelab panning hit and recovered around 3.5 grams of flakes also. Best equipment on the planet I couldnt be happier with the PI performance provided.
