DVL A125
The DVL-A125 is the world’s smallest long range Doppler Velocity Log.
With an extremely wide operating altitude of 5 cm to 125 meter, the A125 is the “swiss army knife” of DVLs!
Offering a very high maximum velocity of 9 meter per second, the A125 is the ideal DVL not only for ROVs but also for USVs and fast AUVs.
