and EPE magazine, the publisher of the Magnetic Field Detector
. Andy don't imagine that somebody can use this for locate treasure at 70-80 meters and depth, a coin at 15 m in distance and 1 m depth!
This can be renamed as
"Magnetic Flind Detector". My deep gratefulness because a friend found treasure with it. And other people too. And other persons found different objects but no yet a treasure. Andy has reason when he use these words "hot spots". Treasure are hot spots!
