Description
VERSATILE SINGLE BEAM ECHO SOUNDER
he D270 is a complete package consisting of the D270 controller, a transducer with built-in temperature probe, and its mounting mast. Operating at a frequency of 200 kHz, the D270 provides a maximum depth measurement capability of 200 meters. Its wireless connection to an optional GNSS RTK receiver is ideal for high accuracy bathymetric surveys. The D270 is particularly well suited for river cross-section surveys and reservoir capacity assessments.
INFORMATION AT A GLANCE
The D270's OLED display provides a quick and comprehensive overview of vital data, including voltage status, water depth, and GNSS satellite tracking. Users can easily switch to view additional information such as water temperature, sound velocity, and draft, making it a versatile and user-friendly way to monitor operations effectively.
GREATER CONVENIENCE AND EFFICIENCY
Bluetooth and Wi-Fi connectivity enhances both convenience and efficiency by enabling wireless setup when used with an optional GNSS receiver. Integrated connectivity streamlines wireless communication and data transfer, increasing workflow efficiency and ensuring seamless bathymetric surveying operations.
ENHANCED OPERATIONAL SAFETY
By giving operators immediate alerts of shallow water and data anomalies, the D270 significantly improves operational safety. Its proactive workflow ensures safe operation and reliable results when conducting bathymetric surveys, even in challenging environments.
