I finally got a little time since the snow is melting and I tried detecting some bare spots in my yard. The ground is froze so digging in some parts was not possible other parts I could break through the frozen ground. I wanted to see how the nox 600 would do under these conditions. I have heavily hunted this part of my yard already. So in about 20 minutes I had a wheat a Memorial , 2 rivets and a nice 14k diamond ring. My very first gold ring and it was in my back yard! Park 2 recovery 3 and sensitivity I turned down from max which is what I used to always run but now I’m trying it down lower as I have read may work better. The ring was a solid 6.
