China Underwater Altimeters

The HY1610 and HY1611 underwater altimeters can measure and display the accurate distance from towed objects to the bottom of the water, thus protecting underwater instruments. Altimeters with operation frequency, 208 kHz and 446 kHz are offered for different depth range survey, and it's allowed to customize as required. At present, the HY1610 and HY1611 are the most advanced and reliable underwater altimeters in China's domestic market.
Intelligentized bathymetry software with abundant function such as automatic survey controlling, dynamic signal detection, identification and tracking, real-time monitoring and controlling, which ensures high accuracy and reliability of the altimeters
Real-time display and storage of the bathymetric data that are transmitted via the serial port.
