I doubt a two box detector will hit gold bars 10 ft under ground. Unless there are many of them stacked together. And now we are talking about something that is very impractical. And unless you own the land you will have no way to dig a hit to check it.
Thanks for taking the time to respond guys.
I do own (fiance' and me) the land. Rice farm that was a spot in the middle of a bamboo forest that was occupied by Japanese soldier's. It's in the Philippine's. Obviously, a long shot and it's a long story as well but nothing ventured/nothing gained.
You guy's were nice enough to respond...I'll let you know if anything comes from it.
