Is resistance ground testing a good way to locate a hidden covered cave. The cave is in bedrock and covered with 4 to 10 feet of overburden. If Resistance testing is usable then how do you read and interpet the device? Can it read through the bedrock? If so how much power is needed to get a reading?
If Resistance testing is not usable what is?
