ABSTRACT:
A single shot surveying instrument which is designed to be lowered to a desired location in a borehole and to take a single picture which indicates the direction of the borehole. The instrument operates in a first mode in which a picture is taken after the passage of a preselected period of time, which period is selected to allow sufficient time for the instrument to be properly positioned in the borehole. The instrument also operates in a second mode in which a picture is taken after the lapse of the preselected period of time if there is an absence of motion by the instrument during a last portion of the preselected time period. An indicator light on the instrument provides a check for premature operation of the instrument and for operability of the motion sensing capability.
