The DVL-A50 is – by far – the world’s smallest commercially available Doppler Velocity Log.

The record breaking 5 cm min altitude makes the A50 extremely useful for working with tools close to the seabed.

With its unbeatable price/performance, the DVL-A50 is now establishing a new market standard.
