Abstract

A device for securing two or more seismic energy sources at fixed relative positions during firing of the sources consists of a rigid framework comprising end frames and intermediate bars. In order to provide an extremely light but at the same time completely rigid framework, the seismic energy sources are used as longitudinal bars between the end elements.
