Baywei M4 Multibeam
Baywei M4 compact shallow-water multibeam. 256 beams, 400 kHz, swath up to 130°, ping rate 50 Hz. Range >200 m. Bathymetry and sidescan out. Weight 3.4 kg in air (1.1 kg in water). Works with QINSy, HYPACK, BeamworX and SonarWiz.
The M4 is the entry professional system in the Baywei line: a high-resolution multibeam for survey boats, small ASVs and AUVs, without GNSS/INS in the head. You add the positioning and motion you already use. The head is compact, hydrodynamic and low-power, so it mobilises quickly on light platforms.
Typical work: harbours, dredging, coastal survey, lakes, archaeology and university programmes.
