Manufacturer of seismic equipments

Original manufacturer of marine seismic instruments since 1970, SIG is an expert in high voltage energy sources, commonly called sparkers.

Portable and reliable sparkers

 We have the only minisparker on the market, designed for the small boat and for one man launching of the sparker-electrode.


To complete the sub-bottom profiling systems, SIG France has also developped its own seismic streamers to be used in high resolution seismics


Several complete turnkey systems, ready for high resolution seismic surveys, are available from the rental pool, and can be shipped to anywhere on simple request.

The sub-bottom profiling instruments are among the tools of marine investigations, available to geophysicists to analyse the seabed, and study the subbottom stratigraphy of marine deposits.


Main advantages and uses :

  • continuous mapping of the sub-bottom sediment layers
  • top bedrock detection
  • pipeline detections

In the oceanographic seismics researches, sparker and boomer profiles give high resolution images of oceanic structures and water column.

  • water column analysis


It is a cost effective method in seabed research programs and civil planning works. Seismic surveys can cover a wide area. Correlation with sea-bed determination can be then done ponctually by drilling methods.


The marine seismic instruments of SIG France are recognized worldwide by

  • marine institutes,
  • national geological surveys,
  • universities geoscience departments, 
  • offshore geophysical survey companies,
  • oceanographic research institutes. 

A complete range of seismic sub-bottom profilers


SIG Pulse, the new product range of seismic sub-bottom profiling systems replaces the former SIG mille series and Energos series, which have been spread on the vessels since 2001.


3 models, all hand-deployed, to be used on small boats for the very shallow, coastal and rivers environments, or on larger vessels for the deep water surveys with applications down to 5000 m of water depths.

Hydrophone streamers single to multi-channels


SIG France manufactures its own hydrophones SIG 16, to be integrated into the seismic streamers.

SIG 16 analog streamers are recognized worldwide for their sensitivity for high resolution and V.H.R. seismics.
