I found a 1 gram nugget the second hour I had the Gold Pro in use. Kinda put the MD on the back burner as I have been crevicing with my Vac. Not to mentioned I have been lazy on buying snake Gaitors and I am not about to go nugget shooting in Arizona without them in the summer. But I will be swinging the MD again soon. Set your gain about 11 O'clock and the Threshold to where you get a little buzz. Your then good to go get a nugget or two.
