The Reef: Water Linked DVL A50 

The DVL A50 is the world’s smallest doppler velocity log. It provides accurate velocity measurements when it’s between 5 cm to 50 m from the seafloor and has a 300 meter depth rating. With ±1% long term accuracy, it is a capable tool for subsea navigation. Using the Water Linked DVL BlueOS Extension, it enables position holding and autonomous navigation capabilities in the BlueROV2 and other vehicles.
