This is also a co-worker of mine that I have been bugging for nearly a year to do a search for his lost ring that he had mentioned. He wasn’t sure where he lost it but assumed it was during a game of catch with his son in the yard nearly 5 years ago (2009.) It was until I recovered another lost ring for a another co-worker that had also been lost for nearly 5 years. He was pretty sure that it would be in a small area next to the driveway. After going over that several times with no luck we moved to the back yard. It’s actually a pretty good size yard, figured it would take about 3-4 hours to go over it quickly. Luckily about half way down the 3rd pass came across a signal that was right in the pull tab range but was a good solid consistent signal. Dug a fairly shallow plug flipped it over and there it was, I looked over my should at him and he had a look of disbelief on his face.
