Applied Acoustics - Model Dura-Spark UHD 240/400 -Sound Source, Sparker
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.
