Description
Introducing The EchoLogger ECT D24S
The EchoLogger ECT D24S is a dual-frequency echo sounder equipped with a tilt and temperature sensor, along with a complete set of accessories, including a harness, housing, and mountings for drone integration.
- Designed for shallow water applications, the ECT D24S features an optimal frequency combination tailored for environments such as ponds, lakes, and rivers with dense seaweed coverage.
- 200 kHz provides continuous bottom reflection, ensuring reliable depth readings.
- 450 kHz is ideal for shallow areas, effectively covering regions where lower frequencies would struggle due to the dead zone effect.
- Additionally, the echo sounder cable is encased in a protective plastic sleeve, which not only shields it from damage but also helps support the weight of the echo sounder and its housing.
- This system is designed for efficient and accurate underwater mapping, making it a valuable tool for drone-based hydrographic surveys.

FAQ's
1. What is the EchoLogger ECT D24S used for?
The ECT D24S is a dual-frequency echo sounder designed for shallow water hydrographic surveys, especially in environments like ponds, lakes, and rivers with dense seaweed coverage.
2. What frequencies does the ECT D24S operate on?
It operates on 200 kHz (for continuous bottom reflection) and 450 kHz (for better coverage in shallow areas, avoiding dead zones).
3. Can the ECT D24S be mounted on drones?
Yes, it comes with a harness, housing, and mountings for drone integration, making it compatible with DJI M350 RTK, M300 RTK, and M600 Pro.
4. How is the echo sounder cable protected?
The cable is encased in a protective plastic sleeve, which not only shields it from damage but also supports the weight of the echo sounder and housing.
5. Why is dual-frequency important for shallow water mapping?
The combination of 200 kHz and 450 kHz allows the system to capture continuous bottom reflections while effectively mapping shallow areas where lower frequencies struggle due to dead zones.
