DVL333 - 6000 m
Bottom-Track From 0.1 to 375 m Range; 6000 m Operational Depth
The DVL333 is a long-range Doppler Velocity Log that benefits from increased range with no compromise in performance or form factor. It allows vehicles to maintain bottom lock in a greater range of environments, increasing mission duration on long-range subsea vehicles. This 333 kHz DVL is used by innovators in the uncrewed vehicle sector looking to expand vehicle capabilities into new environments.
Description
Highlights
