Marine sparkers are among most widely used high and ultra-high resolution seismic sources for reflection marine seismic surveys.
Modern sparkers are used for all types of engineering and scientific applications and operate in wide range of water depth - from first meters up to several kilometers, providing detailed, high-resolution images of subsurface.

... discharge technology and unique tip material. They do not require frequent maintanence even while working on large energies. To increase weather operational window and low energy content sparkers can be towed up to 5 m depth.
Additionaly, multi-level sparkers working with MultiJack energy sources support cutting-edge shooting technology – pre-defined delay is used to shoot at each sparker level for each shot. This results in constructive interference of wavefields, generated by each level, resulting in increasing low frequency energy,...
