300 m

Tracking du fond de 0.3 à 380 m. Profondeur opérationnelle de 300 m.


The DVL333 is a universal Doppler Velocity Log that combines compact design with unprecedented functionality. It can fly higher in the water column and closer to the seabed than similar equipment. This 333 kHz Doppler Velocity Log is used by industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.

  • Currents
  • Bottom track

Points forts

  • Bottom track from 0.3-380 m range
  • Per-ping and per-beam data quality estimates
  • 300 m operational depth


  • Highly accurate subsea surveys
  • AUVs with long missions or high accuracy requirements
  • Easy integration with leading inertial navigation systems (INS)


With the longest range of the Nortek DVL family, this 300m rated survey-grade DVL is equipped for easy integration with leading INS systems to create a robust, reliable navigation system with maximized range. As with all of Nortek's DVLs, the DVL333 Compact is compatible with top control software including EIVA, Seebyte and Greensea.


Tested in demanding conditions in the Oslo fjord, the DVL333 Compact has a proven track record in areas of variable bathymetry and conditions. The water track feature provides a velocity backup if the bottom becomes out of range. The spectrum analyzer assures thorough system level integration.


The DVL333 Compact provides reliable navigation in the most demanding conditions across multiple platforms. The addition of simultaneous current profiles improves operational safety and allows opportunistic oceanographic data collection.
