450 kHz. 5° Narrow Beam. 0.15m Minimum Range.
The ECT 400S operates at 450 kHz with a 5° conical beam — delivering exceptional bottom resolution and minimal off-axis interference in shallow water environments. With a minimum measurement range of just 0.15 meters, the ECT 400S covers ultra-shallow areas inaccessible to lower-frequency sensors limited by dead zone constraints. Built-in tilt and temperature sensors ensure data accuracy throughout dynamic UAV survey operations, while RS232 SkyHub integration enables seamless georeferenced data acquisition.

High-Resolution Shallow Water Bathymetry. 450 kHz. Drone-Ready.
The EchoLogger ECT 400S is a professional-grade single-frequency echo sounder engineered for UAV-based hydrographic surveying in shallow water environments. Operating at 450 kHz with a tight 5° beam angle, the ECT 400S delivers high-resolution bottom detection from as shallow as 0.15 meters down to 100 meters — making it the precision choice for ultra-shallow surveys where low-frequency sensors are rendered ineffective by dead zone limitations. Purpose-built for SkyHub RS232 integration, the ECT 400S transforms DJI Matrice platforms into capable, georeferenced bathymetric survey systems.
450 kHz — 5° Narrow Beam for High-Resolution Detection
The ECT 400S's 450 kHz single-frequency operation with a 5° conical beam delivers exceptional bottom resolution in shallow water conditions. The narrow beam minimizes off-axis returns and side-lobe interference, producing clean, high-fidelity depth data in complex shallow environments including ponds, rivers, reservoirs, and coastal zones where precision matters most.
0.15m Minimum Range — Ultra-Shallow Coverage
With a minimum measurement range of just 0.15 meters, the ECT 400S covers ultra-shallow areas that are inaccessible to lower-frequency sensors limited by their dead zone. From near-surface to 100 meters depth, the ECT 400S provides complete bathymetric coverage across the full shallow-water survey envelope.
Integrated Tilt & Temperature Sensors
Built-in tilt and temperature sensors ensure measurement accuracy and data quality throughout the survey flight. Tilt compensation accounts for aircraft attitude variations during dynamic UAV operations, while temperature data supports sound velocity correction for precise depth calculations in varying water conditions.
