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 a vertical resolution of up to 25cms, in water depths from 5 to 1000 metres.
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, if ever, need replacement. The Dura-Spark UHD consists of either 5 or 3 arrays of 80 tips that allow the operator to tune the source from the vessel to its application. This flexibility, together with selectable source depth, allows the sound source to be used in both shallow and deep waters.
The typical operational bandwidth is 300Hz to 1.2kHz and when coupled with the CSP-Nv Seismic Power Supply the system offers 2000J/s peak discharge rate, as well as industry-leading design and safety standards.
