DVL500 - 6000 m

Bottom-track from 0.3 to 200 m range; 300 m or 6000 m operational depth

The DVL500 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. Maximum operational depth is 6000m. This 500kHz doppler velocity log is used by industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.
