DVL1000 - 300 m

DVL1000 - 300 m

Bottom-track from over 0.2 to 75 m range; 300 m or 4000 m operational depth

The DVL1000 is the world’s smallest survey-grade Doppler Velocity Log. It combines compact design with unprecedented functionality, being able to fly higher in the water column and closer to the seabed than similar equipment. This version has a maximum operational depth of 300 m and is ideally suited for subsea navigation where size and weight are a concern. This 1 MHz DVL is used by industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.
