Nortek DVL 1000 - 4000m

Bottom-track from over 0.2 to 75 m range; 4000 m max. operational depth

The DVL1000 is the world’s smallest commercially available doppler velocity log. It combines a compact design with unprecedented functionality, being able to fly higher in the water column and closer to the seabed than similar equipment. It has a maximum operational depth of 4000m and is ideally suited for subsea navigation where size and weight are a concern.

Description

The DVL1000 is the world’s smallest commercially available 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. It has a maximum operational depth of 4000 m and is ideally suited for subsea navigation where size and weight are a concern. This 1 MHz Doppler Velocity Log is used by
industry leaders in the subsea market because of its high accuracy and state-of-the-art technology.
