A METHOD OF DETERMINING THE EXTENT OF DEVIATION FROM THE VERTICAL OF A BORED HOLE WHICH EXTENDS INTO THE EARTH, COMPRISING: (A) LOCATING OVER SAID BORED HOLE A ROTATABLE SONAR DEVICE CAPABLE OF DERIVING A SIGNAL AS IT ROTATES WHICH IS A FUNCTION OF THE DISTANCE BETWEEN THE DEVICE AND THE PERIPHERY OF SAID BORED HOLE AS MEASURED IN THE DIRECTION THE DEVICE IS ORIENTED, (B) LOWERING SAID DEVICE INTO SAID BORED HOLE AND ROTATING SAID SONAR DEVICE AT DISCRETE INTERVALS OF DEPTH IN SAID BORED HOLE TO DETERMINE THE RELATIVE POSITION OF SAID DEVICE WITH RESPECT TO SAID PERIPHERY OF SAID BORED HOLE, (C) NOTING SAID RELATIVE POSITION OF SAID DEVICE WHEN IT APPROACHES THE PERIPHERY OF SAID BORED HOLE AND THE DEPTH OF SAID DEVICE, (D) MOVING SAID DEVICE TO A MORE CENTRAL POSITION IN SAID BORED HOLE AT SAID LAST MENTIONED DEPTH AND NOTING THE CHANGE IN RELATIVE POSITION WITH RESPECT TO SAID PERIPHERY BEFORE AND AFTER SAID DEVICE IS MOVED TO A MORE CENTRAL POSITION, (E) CONTINUING TO LOWER SAID DEVICE AND DETERMINE THE RELATIVE POSITION OF SAID DEVICE WITH RESPECT TO SAID PERIPHERY OF SAID BORED HOLE AT DISCRETE INTERVALS OF DEPTH.
