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 and bottom-mount solutions are available and designed to fit Eco off-the-shelf. Eco is portable enough to be put in the water 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 echosounder data, Eco does present a host of new, unique capabilities.

The Eco is configured online via the Eco WebApp through Bluetooth communication. Users need only to input their desired measurement interval (as little as 2min or as much as 1hr) and expected water salinity (fresh, salt, or a mix). Designed specifically for first-time users and students, the WebApp is also used to configure the Eco’s accompanying timed release.
Two off-the-shelf deployment solutions are available for the Eco: a tripod for bottom-mounted deployments in shallow water, and a buoy system with a timed release for deployments in slightly deeper water. An LED on the Eco displays the Eco’s status and assures users of function.
After recovery of the Eco, data is loaded back onto the WebApp via Bluetooth. Data processing is done automatically, including data quality controls accounting for sidelobe and fish interference, bin mapping and other common issues. Users are presented with current velocity in three depth layers. Raw data cannot be accessed.
