Eco - 50 m

Shallow-water current profiles in a groundbreaking new package.
Appropriate for first-time ADCP users, small budgets or educational use.

The Eco current profiler is the first ADCP right-sized and designed specifically for shallow-water measurements. It
allows you to measure water velocities in situ, through the water column using the same acoustic Doppler
technology as other Nortek instruments, but in a more affordable and easy-to-use package. Simple buoy andbottom-mount solutions are available and designed to fit Eco off-the-shelf. Eco is portable enough to be put in thewater from a paddle board or kayak by one person. While the Eco does not feature many of the more complex
capabilities of other Nortek instruments, such as wave measurements, turbulence estimation, or echosounderdata, Eco does present a host of new, unique capabilities.
