First time out with the Gold bug Pro with 11 inch coil. I decided to give it a real test and hunt around the fire rings at the beach. The area around these are littered with rusty nails and aluminum blobs and the usual trash. It started raining so I only had about an hour. I was very impressed that I could pick out good targets without digging any nails. The aluminum blobs still got detected but I can live with that. In one hour I got several coins including nickels and two rings - a heavy silver ring and and one of those titanium rings. When I scooped up the silver ring it came up with several nails in the same scoop. No problem with hearing the good targets. The fact the nickels rang good in this trash indicated that gold rings wouldn't be missed. I look forward to running some more tests in the trashiest areas where I don't dare use my Whites's PI.
