The patent relates to an apparatus which provides a continuous, timed record of corer orientation data including corer declination, inclination, vertical acceleration. A compass, bubble levels, an accelerometer and a clock continuusly provide the data. Indicators for these mechanisms are disposed in the focal plane of a battery-driven motion picture camera coupled into a switching circuit which also includes camera lights. A switching mechanism using a magnetic reed switch energizes the camera, lights etcetera at the moment the corer is released to begin its free-fall into sediment penetration.
