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