Hi, I couldn't wait to get the Equinox 800 to Arizona for some gold prospecting especially since the area in Colorado where I live is frozen pretty solid.  The first site I hunted was in the Little San Domingo Wash area which has been pounded by lots of people for over a hundred years. I used the Nox 800 exclusively in Gold 2 with the 6" coil due to an abundance of human metallic trash, with sensitivity at 15 to 16 (falsed over those settings) with -9 to -4 discriminated out, iron bias
