On a ridge with overburden of between 1 and 15 feet over solid granite, how deep can one expect the TM 808 to show a covered tunnel of perhaps a few feet or larger in diamater? I would appreciate any information from folks whom have used one that might know. Also, would it it read to the same depth in solid rock as in other soil? Thanks.
