Model: T400S
Features
Applications
Specification
The revolutionary T400S focuses on intelligent, integrated and high precision of multibeam echosounder system. Its ultra-compact design can be easily operated by one person and suitable for USV, ROV, AUV platforms.
The number of 512 beams can provide you with high precision me-asurement result. Because of IMU built-in receiver, this system does not need calibration. With low power consumption, it is also suitable to operate from battery.
T400S, small, lightweight and cost-effective could be your best choice.
