I taught a young boy and his father some basics of metal detecting this evening.I left my CZ 70,spare batteries,a pair of Grey Ghost headphones and a new Lesch digger with him.The first 2 signals "we found " were coins.They're both hooked.I'm going fishing and detecting at my cabin for a week.I'll check back with them then.The boy picked up on pinpointing and good mechanics of his swing quicker than his dad.His father was dumbfounded there were coins in his yard.The house was built in 1934.I told them I expect to see some "goodies" upon my return.Their journey begins.
