This resistivity meter has been designed specially for archeology and treasure hunting.
Resistivity meter is useful to locating non metal large objects in soil , as tunnels , structures ........

Maximal detection depth to object sizes AxAxA meters is Am. As example if object is 4x4 meters the maximal depth will be 4 meter.
Maximal detection depth to long tunnel high A meters is 2xA meters. As example if the tunnel is high 2 meters the maximal depth will be 4 meter.
You can read: "The resistivity method is not particularly sensitive to 3-D anomalies for the same reason that it is ineffective over buried 2-D structures of finite width."
