Blueview BV5000
Underwater 3D Imaging Sonar
BlueView's BV5000-1350 and BV5000-2250 3D mechanical scanning sonar create high resolution imagery of underwater areas, structures, and objects. With the touch of a button, these new 3D mechanical scanning sonar create 3D point clouds of an underwater scene with minimal training required. The compact, lightweight units are easily deployed on a tripod or an ROV. The scanning sonar head and integrated mechanical pan and tilt mechanism generate both sector scans and spherical scan data. For the first time, get 3D laser-like scanning capabilities underwater, even in low and zero visibility conditions and seamless integration with traditional laser scan imagery
  • 3D site survey
  • 3D structure inspection
  • Oil rig decommissioning
  • Bridge inspections
  • NEW! BlueView metrology


  • Easy, one touch scan function
  • 3D mosaic imaging without position info
  • Easily combined with laser scan imagery
  • Compact size fits into tight spaces
  • Operates in low & zero visibility conditions
