I was hunting a trail in the woods above a creek. The SEF 8x6 was attached with the sensitivity set at 18. I retrieved a nickel that gave a solid 13, two twenty gauge caps, a vaccination tag, and a 1954 Rosie. The nickel turned out the be a 1941. It is very corroded. The Rosie is my first silver with the Safari. It read as 38 with a clear, repeatable signal. The depth was only about an inch and a half.
