The product was successfully added to basket
Main features:

  • Acceleration-insensitive hydrophone

  • Small diameter

  • Different filling materials

The towed linear hydrophone array HRStreamer is designed to be used as a receiving system for performing high-resolution seismic operations in the water area with continuous seismoacoustic profiling (СSP), high-resolution (HR) or super-ultra-high-resolution / super-high-resolution (SUHR / SHR) and other methods. Sensitive elements of the cable system are high-sensitivity hydrophones with signals preamplifiers. The number of channels in array can vary from 1 to 48. As filling materials the polymers of different consistency, natural or synthetic oil can be used. Maximum working pressure of 40 atm. allows one to use cable systems in order to implement a buried observation system.


In addition to HRStreamer the following items can be purchased: 

  • High-frequency seismic station 

  • Deck winch

  •  Towed buoys with positioning system 

  • Paravan for 3D system 

  • Towed sparkers and boomers with MultiJack power supplies 

  • Software for quality control and data processing.
