Wife gave me a 600 for my birthday last week. I have been trying to figure it out as it's much different from my Garrett At and my Tesoro Silver Umax. Have not used a Minelab,in a long time. This morning I took it to a place that I have detected many times and only found memorial penny's and a bunch of iron. This morning I found six Wheaties , two Roosevelt dimes and some modern clad. Now remember I've been over this same 10' x 20' area many times. I have read all the negative comments but so far I'm impressed. I still have to figure out all of the sounds and settings but I am encouraged !!
