EchoLogger ECT D24S Dual-Frequency Echo Sounder for Shallow-Water Bathymetry
The EchoLogger ECT D24S is a dual-frequency UAV echo sounder tuned for shallow ponds, lakes and rivers — including weed-choked water that defeats other sounders. Its 200 kHz channel returns a continuous reflection from the bottom, while the 450 kHz channel covers very shallow areas where lower frequencies fail because of the dead zone. Drone-deployed and SkyHub-connected, it maps water depth from the air where boats cannot reach.
Echo Sounder ECT D24S Dual Frequency
Built for shallow, weedy water
The 200/450 kHz pairing is the optimal combination for shallow ponds, lakes and rivers with heavy weed growth. 200 kHz reports a continuous bottom reflection, and 450 kHz reaches the shallowest areas where a single low frequency would be blinded by its dead zone — so you capture a clean depth profile end to end.
Light, field-ready and SkyHub-connected
At just 1.3 kg the D24S flies under DJI Matrice, Inspired Flight and WISPR enterprise UAVs. Integrated tilt and temperature sensors correct every reading, and the RS232 interface connects straight to SkyHub, which logs georeferenced depth data alongside UgCS flight automation for processing in DroneGIS.
Applications
Water-depth mapping and bathymetry, dredging planning and monitoring, tailings storage facility (TSF) monitoring, wastewater and stormwater surveying, and hydrology studies.
Service & Warranty
Supplied by GulfNet Emirates Drone & Robotic Systems with UAE-based technical support, integration guidance and full manufacturer warranty. The ECT D24S requires additional components and software for drone operation — request a quote and our team will propose the complete, ready-to-fly bathymetry kit.

Frequently Asked Questions
What makes the D24S different from the D052S?
The D24S uses 200/450 kHz, optimised for shallow water and weedy ponds/lakes/rivers, and does not measure sediment. The D052S uses 50/200 kHz, reaches deeper and adds sediment profiling. Choose the D24S for clean shallow-water depth, the D052S for deeper water and sediment data.
Can it be used straight out of the box with my drone?
No — additional components and software (including the SkyHub onboard computer and UgCS flight planning) are required. When you request a quote, we propose the complete set of items for your aircraft.
Which drones are supported?
DJI M400, M350 and M300, Inspired Flight IF800 and IF1200A, and WISPR RangerPro.
What depth range and accuracy can I expect?
0.15 m to 200 m depending on frequency, with 1 mm range resolution and accuracy of 0.2% of the measured depth.
How is the data recorded and processed?
The sensor connects via RS232 to the SkyHub onboard computer, which logs georeferenced depth data in flight. Surveys are automated with UgCS and processed in DroneGIS.
