Product Introduction
Doppler Velocity Log (DVL) – High-Precision Commercial Grade The WaterLinked DVL-A125 is the world’s smallest long-range (125m) Doppler Velocity Log. Capable of maintaining bottom lock at high speeds of up to 9m/s with an altitude range of (125m) , the A125 is the ideal DVL for Remotely Operated Vehicles (ROVs), Unmanned Surface Vehicles (USVs), and Autonomous Underwater Vehicles (AUVs). The DVL-A125 can operate at an ultra-low altitude of just 5cm, demonstrating exceptional performance across both short-range and long-range applications. |
