D270 Echosounder

The D270 is a portable single-beam echosounder that can be easily integrated into USVs for a wide variety of high-accuracy bathymetric survey applications such as cross-sectional river surveys and reservoir capacity assessments. It features a built-in water temperature sensor that enables real-time sound velocity correction for enhanced depth measurement accuracy.

The Linux-based unit features intuitive web-based configuration and chart plotting, with 8GB of internal storage for extensive bathymetric survey data. The OLED display provides a comprehensive overview of a range of critical information, including voltage status, water depth, and GNSS satellite tracking, as well as more in-depth views of water temperature, sound velocity, and draft.

The D270 offers both Bluetooth and Wi-Fi connectivity, and supports optional wireless connection to a GNSS RTK receiver.
