An Doppler Velocity Logger (speed) is an instrument used to measure high precision underwater navigation and positioning. The frequency of the ADCP will determine the maximum range in Bottom Tracking and Current Profiling. All of our ADCP will come with both Bottom Track and Current Profiling functionality. Bottom Track is used to measure the speed and direction of the vessel. Current profiling is used to measure the speed and direction of the water. Bottom Track also includes the depth of the water for bathymetry and surveying. Our DVLs come in all shapes and sizes. With our OEM, you can also design your own custom shape or size.

Internally all of our DVLs come with the same features and the same electronics.
The only options you need to determine are:

The maximum range you need to measure in Bottom Track and/or Current Profiling?

How many beams will you need?

What limitations in size does your vehicle have?

OEM

Custom Designed DVLs and ADCP

A custom designed ADCP. If none of these configurations work for you, we can supply you the transducers and electronics and you design your own mechanical parts. This allows the user to keep the stream line design of their system and also incorporate an ADCP.
