Got out with the Omega this afternoon for about 3 hrs at one of the local parks, decided to use the factory gb setting, sens @90 and tried to detect with the disc set just above iron but there was way to many pull tabs and bottle caps so ended up setting it at 80 and stilll ended up digging a bunch of trash but ended the day with $2.43 (13 of the coins were dimes), a key and what looks to be the body of a ladies watch and a small part of the band. Had a couple of screwy signals a zinc penny gave a vdi of 77 but the tdi was a screw cap and had several crown bottle tops id as a dime but I didn't pay close enough attention to the vdi numbers. All in all a good day got to detect, found some money and got to know my machine a little better. HH Jimmie
