I stayed for 2 days in Dewey beach De. I stayed at the surf club right on the beach. Detected with the Nox600, what a nice machine. I found a total of 12 cents. Dime and 2 zincolns. Found a small toe bling ring, junk. But I found a lot of small pieces of copper, They all had some kind of seration marks on them. What amazed me was how deep the Nox is in beach 1, I use it for dry sand. I use beach 2 for wet and surf .I dug down over a foot for some pieces copper, I mean they were almost invisable. Some kept falling trough the scoop holes and I had to get down and look to see what they were. But still had a great day.
