Overview
The 1200MB pairs the HydroBoat 1200 hull with an all-in-one multibeam unit: transducer, deck electronics, IMU and GNSS in one housing. It maps a full swath of the bed instead of a single line of points, which suits channel maintenance, berth surveys, intake structures and dam faces. Sound velocity inversion removes the need for a separate SVP cast on most jobs.
Key features
- Integrated multibeam: 400 kHz, 512 beams, 30° to 150° swath
- Depth range 0.2 to 200 m, 1 cm vertical resolution
- Heading 0.08° (2 m baseline), roll and pitch 0.03°
- Sound velocity inversion, so no SVP cast needed on most jobs
- Auto return on low battery, auto reverse in shallow water, obstacle avoidance
- Manual, autopilot and auto-return modes
