Hello, I've been metal detecting for more than 16 years, but me, my dad and my uncles are also work in mining, and always with Minelab detectors.
I am a former employee of Minelab Americas DIOGO MILK, in early February I returned to mining work using a Minelab detector, the commander GPX 5000 with the 18" coil.
Within the first week, I was lucky to get a nugget 130 grams, was about 1.2 meter deep.
I was very happy. I advise all detectorists and prospectors buy a GPX5000.
