Geostuff - Model RS-96/24 & RS-120/48 - Rollalong Switches - Brochure

Rollalong switches are designed to automate the process of collecting continuous reflection surveys efficiently. In practice, more geophones are laid on the ground than channels available on the seismograph. The Rollalong Switch selects a subset of the available geophones for each shot point. The active geophones are moved along the ground electrically instead of physically each time the shot point is moved.
