Imaging Sonars
Forward-looking, side-scan, and 3D sonar for ROV navigation, inspection, and search & recovery. See structures, wreckage, and seafloor in real time.
Subsea Positioning
USBL systems, ROV Locators, and DVL technology that pinpoint your ROV in real time on a map — from entry-level to full professional grade.
Bathymetry
Multibeam and single-beam echosounders that generate professional depth maps from small USVs, ROVs, and AUVs — at a fraction of traditional survey costs.
SonarView Software
Free cross-platform software that controls your hardware, visualizes sonar data live, and exports survey results. Runs on Windows, macOS, Linux, and BlueOS.
Breaking Down the Cost Barrier
Cerulean Sonar was founded with one mission: make professional-grade underwater acoustic technology accessible to researchers, explorers, and operators worldwide.
Accessible Pricing
Industry-leading performance at a fraction of traditional sonar costs — opening possibilities for small teams, universities, and commercial operators.
Simple Integration
Standard 100BaseT Ethernet interface, 10–30V power input, and full software support make integration with any ROV or USV platform straightforward.
High Resolution
450 kHz operating frequency and up to 1/1200th range resolution deliver imaging quality that rivals systems costing many times more.
Platform Agnostic
SonarView software runs on Windows, macOS, Linux, and in-browser via BlueOS. Works with BlueRobotics, Blueye, QYSEA, Chasing, and more.
Designed to Integrate
Cerulean Sonar products are validated and optimized for integration with leading ROV and USV platforms.
