Cerulean Omniscan 450 Side Scan Sonar
The Cerulean Omniscan 450 is a compact side-scan sonar module that emits acoustic pulses and captures returning echoes to produce detailed imagery of the seafloor. Mountable on uncrewed vessels (ROVs/USVs) or fixed platforms, it’s ideal for seabed mapping, shipwreck hunting, marine archaeology, ecosystem surveys and search-and-recovery operations.
What is Side Scan Sonar?
A side scan sonar is a type of imaging sonar that allows you to quickly collect imagery of the seafloor to map large areas. The side scan transducers have a narrow, tall beam shape so that when they are mounted to either side of the boat, they have a full 180-degree view under the boat.
When scanning, the transducers emit an acoustic pulse and then record the response as echoes return from the seafloor. That creates a slice of an image and as the boat moves forward, the image is filled in.
This side scan sonar uses 450 kHz transducers, which provide a 150 meter range with detailed resolution, making it ideal for high-resolution underwater surveys and mapping operations.
