Sound Source, Sparkers

The Dura-Spark L80 has been designed to provide a lightweight stable, repeatable sound source for sub-bottom geophysical surveys. The long-life, durable electrodes produce a consistent pulse signature and keep operational maintenance to a minimum. This provides increased survey efficiency and equipment reliability as the sparker tips rarely need replacement.

The Dura-Spark L200 consists of two banks of 100 tips that allow the operator to tune the source from the vessel to its application. Each bank can be fired independently, in Flip-Flop mode, combined with Fire-Delay or a Split-Fire delay. This flexibility, together with selectable source depth, allows the sound source to be used in both shallow and deep waters for multiple seismic data-gathering applications.

The Dura-Spark UHD 240/400 system consists of a negative voltage seismic energy source, the CSP-Nv, a sparker sound source with up to 400 long-life tips, connected by a rugged high voltage cable. Designed for high and ultra-high resolution geophysical surveys, and for use with single and multi-channel acquisition systems, the system is capable of providing high quality data with vertical resolution of up to 25cms, in water depths from 5 to 1000 metres.

The Dura-Spark UHD 400+400 consists of two decks of 400 tips that allow the operator to tune the source from the vessel to its application. Each deck can be fired independently by its seismic power supply, in Flip-Flop mode, combined with Fire-Delay or a Split-Fire delay.

The Delta Sparker is the most powerful sparker available
in the applied acoustics range and is intended for deeper penetration sub-bottom profiling. As a multi-tip sparker array, the Delta can be used in UHR multi-channel seismic surveys, utilising 24 or 48 channel streamers during geohazard assessment, construction projects or shallow target 2D exploration.
