Hi All, any of you Fisher f75 users have a recommended technique on finding gold jewelry such as: rings chains? The settings I normally use are: Sens 80-90, disc 0 - 15, notch 1, AM mode, and sometimes BP mode, 2 tone. I have no problem finding quarters, dimes, nickels all day long. But, whenever I get either a 19 or 22 VDI number, with a steady solid wooping tone; hoping that it is gold, I always end up digging foil. Jumpy sigmals are usually trash. I usually hit the local parks. and dry sand at the beach. I'm thinking about getting an AT PRO for the wet sand and water later in the near future. It seems like all the jewelry is in the water or wet sand.Any suggestions would be appreciated as far as finding jewelry at the parks with the F75.
