The Delta Sparker is our most powerful sparker available in the range and is intended for higher penetration sub-bottom profiling and thus offers a lower frequency sound pulse. Stable under tow, the frame is buoyed and is easily deployed.

As a multi-tip sparker array, the Delta can also be used in UHR multi-channel seismic surveys utilising 24 or 48 channel streamers such as during geohazard assessment, construction projects or shallow target
2D exploration.

Different sparker tips, single or multiple arrangements, can be used to increase resolution or penetration as required. The tips are easily replaceable for simple field maintenance.
