Demonstrating how i hunt with the outlaw, I know now that when using no motion the disc knobb is the gain if it starts to humm to much i turn it a bit clockwise, and like it set left until it just barly humms, now if the dial keeps moving ever clock wise i just put it back to 9:00and press retune. I have dibre taken from an old house that is pread in the feild, it may harber coins but so far just cut nails and broken cast iron stove parts and burnt foundation rock the house was built in 1879 and burned in 1926[video]http://www.youtube.com/watch?v=uN7iGgOD7kI&feature=youtu.be[/video]
