CHC Navigation (CHCNAV) has released the D270, a new single-beam echosounder designed for reliable depth measurement in a range of marine environments. With a 200 kHz frequency and a built-in temperature sensor for real-time sound velocity correction, the D270 echosounder is ideal for a variety of USV (uncrewed surface vessel) applications, including river cross-section measurements, reservoir capacity assessments, environmental monitoring, and dredging volume analyses.
The D270 adapts to changing water conditions while minimizing acoustic interference for reliable data collection. Its built-in temperature sensor enables real-time sound velocity correction, significantly improving measurement accuracy. With 8GB of onboard storage, the unit securely captures large volumes of survey data, and its embedded Linux system supports web-based parameter configuration and chart plotting. Data can also be transferred wirelessly to other devices using Wi-Fi and Bluetooth for improved workflow efficiency.
The D230 features a rugged IP67-rated waterproof and dustproof design. Operators are alerted to shallow water and data anomalies, ensuring safe operation and reliable survey results even in challenging environments.
Taxiya Wang, Product Manager at CHC Navigation, commented: “The D270 provides surveyors with an optimal balance of performance, portability, and value. Its rugged, IP67-rated design, easy-to-use wireless connectivity, and highly efficient workflow give users precise echo-sounding capabilities in a lightweight solution.”
