Metal Detecting/Treasure Hunting
Various types of metal buried underground can be
detected electronically even though it is under several inches of dirt or sand.
The device used is called a metal detector and can vary from a simple (cheap)
unit which works very poorly, to elaborate computerized models costing many
hundreds of dollars (up to $1000 or more). These high-tech models are very
sensitive and can easily find lost rings, coins, small gold nuggets etc.
