Had some time to take advantage of the "warmer" weather so I hit a park close to home; one I've pounded for the last 2 years or so. Everytime I think I've gotten all I can get out of this one, I get a surprise
Funny thing is, I got the iffy signal and dug down pretty deep... no target, just a lot of iron around. I thought what I originally heard was some falsing so I filled the hole in. For the heck of it, I rechecked it and there it was again; actually sounded pretty good. I pinpointed about 1" away from where I originally dug. Dug down around the same depth and found another Merc. Sure glad I decided to re-dig
