Got permission to hunt a 50's-60's house yesterday so I headed out there this afternoon after keeping a doctor's appointment. Anyway, I started by what was left of a falling down carport type of structure. Didn't hit anything but, I kept going around a pile of 6 sheets of corrugated tin. I put my X-70 down and moved the sheets out of the way and proceeded to detect where the sheets had been. Right away a got a warbly -8 in AM mode. I was going to go on but decided what the heck I'll see what it is. Down about, maybe 2" I spotted my find. This is my first one ever. Did a happy dance and headed home, knees were a little sore from cortisone shots in them. Gotta go back.
