Echologger AA400 upgraded
Echologger AA400 is an ultra-compact sonar altimeter with a data logging facility. The device is a sought-after gadget for scientists who study sediment monitoring for long period of time. With the recent upgrade, the device can collect for much longer period of time, for example with 5Hz continuous pings for more than 4 days or 10 Hz pings for more than 2 days without a break.
With its versatile settings, the device can also collect data for 250 days at 10Hz pings (for 5 seconds) with 10minute intervals.
Exceptionally low power consumption and ultra-light design enabled researchers to study sediment move more efficiently and accurately in shallow water and in ocean depth up to 6,000m alike.
