MS400C

Fully All-in-one Multibeam Echo Sounder

MS400C revolutionizes multibeam technology as an all-in-one echosounder integrating SVS, IMU, GNSS and deck unit entirely within its compact sonar head. This innovation exemplifies Hydro-Tech’s leadership in miniaturized intelligent sonar systems. Weighing just 5.55kg, the bathymetric system enables effortless deployment on small USVs while maintaining reliable performance.

Features

Fully All-in-one: Combine transducer, SVS, IMU, GNSS and deck unit into a single compact housing. Require only three cable connections: power/data transmission and dual GNSS antennas. Greatly change the traditional installation method of multibeam bathymetric USV.
Easy Operation: Fewer parts and connecting cables enable simpler and quicker operation. Eliminate deck unit installation and save space for other USV equipment. Solve the problem of heat dissipation inside the USV cabin, even in extreme hot summer.
Plug and Play Convenience: All position relationships of IMU & transducer center and USV GNSS antenna are fixed and set up in the software already. Start to collect data in just 5 minutes with simple installation and auto-survey settings. Reduce complexity and boost survey efficiency.
