In 1964 I was a new Boy Scout wearing my uniform for the first time. Naturally I lost my kerchief slide and never found it even though I was sure I knew where I had to have lost it. I searched for it many times.
Last year I was passing the church where my troop met and had my detector. I got out and made half a dozen swings and got a hard signal right where I had searched so many times. Four inches down and 49 years later I finally found my kerchief slide.
Nice find! Congrats.
