Imaging Sonar
Omniscan 3D 450 SS
The Omniscan 3D 450 SS fills the gap between conventional side-scan sonar and a full multibeam echosounder. A 16-channel receive array calculates the vertical angle of every acoustic return, generating high-resolution 3D point clouds of the seafloor in real time at 450 kHz.

In the box, and what it does not include
A sonar is not a system. These are the parts you will need alongside it — each one with Cerulean’s own source.
What’s in the box
- Omniscan 3D all-in-one unit
- 4-pin JST-GH to JST-GH jumper
- 4-pin JST-GH to JST-GH adapter
- 4-pin JST-GH to RJ45 (female) adapter
- Penetrator O-ring and nut
What else you need
- SonarView, on a computerFree with the device. The 3D mesh and the point cloud are built live in SonarView. Source →
- Position and headingThe point cloud has to be placed somewhere. SonarView takes this from the vehicle over MAVLink2Rest, or from NMEA. Source →
- 12–30 V DC and one Ethernet portA Raspberry Pi 5 and an Ethernet switch are already inside the all-in-one unit, so it needs no extra enclosure or computer. Source →
We supply the brackets, hubs, cables and spares alongside the unit — see what fits Omniscan 3D 450 SS → or add them to the same enquiry.
Common questions
Answers Cerulean publish, each linked back to the page it came from.
What does the 3D actually add?
A conventional side scan lays its image on a flat plane. The Omniscan 3D has a 16-channel receive array that works out the vertical angle of every return, so SonarView can build a true 3D mesh and drape the image on it — and everything standing up in the water column comes out as a point cloud. Source
Is it a replacement for a multibeam?
No. Cerulean position it between an interferometric side scan and a multibeam echosounder. It is very good at wide swaths in shallow water. For survey-grade bathymetry the Surveyor 240-16 is the multibeam. Source
Do I need an extra computer or housing?
No. The all-in-one unit has a Raspberry Pi 5 and an Ethernet switch inside and is fully self-contained. All the beamforming happens on the device, so it also needs less network bandwidth. Units can be chained through the built-in switch. Source
Can I upgrade an Omniscan 450 I already own?
Not any more. The RX16 Upgrade Kit that did this is no longer available for sale — Cerulean state so in the documentation. The all-in-one is the current route to 3D. Source
How should it be mounted?
30–45° downward from horizontal. Source
