I should state that I my experience is based on California soil (very high mineral). I wanted to bounce a few things off you guys and see if you agree or think I'm missing some high value items. Keep in mind I'm talking about California soil. Usually everywhere I hunt is at least moderate to high trash so I tend to use C & J mode to help sort threw it. I have had my Safari since Christmas and have found 3 gold rings, 2 gold bracelets and 6 silver rings. Also a ton of coins but nothing very old. I use the sounds way more than the ID # (look at it for more of just a reference). Anyhow, I dig 1-11 and 38 and above ONLY. Does anyone think or have experience finding any high value items at any other numbers. A lot of people talk about diamond rings at 15 but I don't think that is California soil. ( we like to do everything different in Cali, apparently even the soil likes to be a pain in the butt compared to everything else). I know I am passing up all nickels but it seems that my best return on time invested is to skip them. Any thoughts or criticism appreciated.
