MB2 Multibeam Echosounder

Product code : 1592538348

The MB2 Multibeam Echosounder is developed for fast mobilization on smaller vessels and is optimized for shallow water survey companies, port and harbor authorities, dredging companies, and other users looking for an easy-to-use and quick-to-deploy high-resolution system.

Quantity:

    As an option MB2 can be supplied with an integrated IMU and GPS heading system as well as an integrated real-time SVP sensor to simplify installation and calibration, making the MB2 perfect for use on vessels of opportunity, small survey launches, and ASVs. MB2 features a dedicated cylindrical transmit array and broad range of sounding frequencies improving on the performance of the MB1 by offering a wider coverage and narrower acoustic beam. Using both amplitude and phase bottom detection, the MB2 is capable of sounding a swath of up to 140° in up to 110m water depth. With 24 bit raw data, both water column and seabed information can be collected within the controller software. The Real Time Appliance (RTA) synchronizes all of the sensors with accuracy better than 0.1ms.
