Last night I got a call from a guy who uses tractors, bulldozers and other heavy equipment to dig graves, haul gravel and dirt, do fill work and also landscape yards for newly built houses. Early yesterday morning he was discing up what was a sage grass field to make the yard for a newly built house, lost his recently purchased Apple 4 G iPhone cellphone and disced it under. He and another guy spent all afternoon hunting for it with detectors but didn't find it and asked me to look for it. This morning I went to search for it and, even though it was nothing but blind luck, I found it in less than 20 minutes. It was three to four inches deep from being turned under with the disc, but still worked and didn't look to be damaged..
