Sensibly Priced.

Acoustic technology for imaging, positioning, and measuring underwater.

Inspect. Explore. Discover.

Imaging

Meet the Omniscan family of acoustic imaging sonars. An innovative scanning sonar with superior image quality, and similar situational awareness to FLS multibeam sonars costing 10x more!

Subsea Positioning

Check out Cerulean’s proven subsea positioning products, the ROV Locator USBL, and Tracker 650 DVL.

Bathymetry

Finally an affordable multibeam echosounder! The Surveyor 240 is a perfect fit for small uncrewed surface vessels (USVs).

SonarView

The Cerulean-developed SonarView application supports all Cerulean sonar products. SonarView is a web application so it is platform agnostic and can run on Windows, Mac or Linux. A SonarView server can be hosted on an ROV or USV giving the user a seamless software experience. In that scenario, SonarView can even be run on any modern web browser.

Cerulean Partners

We are proud to be working with leading ROV manufacturers around the world to integrate cost effective Cerulean Sonar products enabling advanced underwater capabilities formerly reserved for the Navy and Big Oil.

BLUE ROBOTICS

The BlueROV2 is an affordable high-performance ROV. With a 6-thruster vectored configuration and plenty of expandability, it is a great ROV for inspections, research, and adventuring. The BlueROV2’s open-source electronics and software have made it a top choice among integrators and value-added resellers worldwide.

Blueye

Professional underwater ROVs designed, developed, produced, and serviced in Norway. Reliable and user-friendly underwater technology for frictionless access to what’s below the surface.

Aquaai Submarine

CHASING

Creators of the Chasing M2 Pro Max, an underwater ROV/Drone designed for professional users and industrial applications. It allows for omni-movement in all directions and has a powerful mount extension system, including an optional robot arm, to meet the needs of multi-professional scenarios.

JM Robotics

JM Robotics has extensive practical experience in both aquaculture and offshore. JM Robotics knows how tough everyday life is at sea and, therefore, creates functional and user-friendly ROV systems that can actually withstand the forces of the ocean.

QYSEA

QYSEA is a technology company that specializes in underwater drones, which are often used for underwater inspections, exploration, and research. QYSEA applies advanced technologies such as real-time video feeds, onshore control systems, and underwater quick positioning systems.

Ken deBoer CTO - Titan Maritime, Canada

Cerulean DVL is my go-to positioning system. It requires little to no calibration and is amply accurate in finding targets of known GPS coordinates. It is fantastic to place a waypoint on the screen and pilot straight to it while seeing the ROV location/track on the screen when navigating!

Peter Schubert - Poseidon Robotics, USA

We use Cerulean DVL-75 and ROV Locator with our Remotely Operated Vehicles product line (Maui and Lanai). I value its simple installation, great performance, and QgroundControl integration where map position is updated without any input or configuration after being connected -- a great value to ROV users.
