  • Patent number: 4398276
    Abstract: A method and apparatus for gathering a geophone sensor string (10) is provided. The geophone sensor string (10) comprises individual sensors (12) for sensing motion of the earth, an interconnecting cable (14) and ring members (22). A line (30) is secured to a ring member (22) at one end of the geophone sensor string. The line is passed through the remaining ring members on the geophone sensor string and extends through the ring member adjacent the opposite end of the geophone sensor string. Drawing the line (30) in the direction of the arrow (32) lifts the sensors off the ground and gathers the sensors and interconnecting cable in an untangled and compact form for storage. The technique of the present invention is adapted for use with vehicles to eliminate manual labor.
