The EchoLogger ECT 400S is a compact, high-precision single-frequency echo-sounder specifically engineered for UAV bathymetric and hydrographic surveys. With a 450 kHz acoustic frequency and a measurement range from ~0.15 m to 100 m, it is ideal for shallow-water depth mapping, sediment profiling, flood-zone monitoring and shoreline asset inspection.

Integrated with tilt and temperature sensors, RS-232 interface and compatible mounting for UAVs like the DJI M300/350 RTK, the ECT 400S supports efficient airborne deployment in otherwise inaccessible or hazardous environments.

Optimize your drone-based survey workflow by reducing field time, removing boat or man-entry requirements, and capturing reliable depth and backscatter data with minimal setup overhead.

EchoLogger ECT 400S FAQ

The ECT 400S system requires a UAV capable of carrying the sensor plus mounting hardware (~1.9 kg) and maintaining stable low-altitude flight for accurate bathymetric data collection. The DJI M300/350 RTK series or similar enterprise platforms are recommended.

The ECT 400S supports surveys from very shallow water (~0.15 m) up to ~100 m when using the 450 kHz frequency. It is particularly effective for shallow-water mapping, vegetated/flowing waters, flood zones, sediment layer detection and inaccessible shoreline or riverbed surveys.

By integrating flight-ready hardware, tilt/temperature sensing, and drone compatible mounting, the ECT 400S enables bathymetric surveys without vessels or manned entry. Paired with onboard logging (via SkyHub), terrain-following drones and downstream processing software, it significantly reduces survey setup time and cost while maintaining high-quality depth and backscatter data.
