To make a long story short I was at a meeting where an old man kept bringing up the fact that 3 time capsules were buried back in 1905. He claimed that the school put jewelry, coins, old maps, etc in them. He claims to know where they are but will not tell anyone the exact location. The only information I got out of him were that the capsules were within 50 feet of an old oak tree next to a small (newly constructed) playground area. I have an ACE 250 and a Tesoro UMax and wanted to know if these detectors were capable of finding time capsules such as these. Are they usually buried pretty deep? Is there a certain technique/method I should use in trying to find them? Any help would be greatly appreciated..!!
