High-Resolution Underwater Imaging
Without the Multibeam Price Tag
The Omniscan 450 series brings professional-grade forward-looking, side-scan and real-time 3D acoustic imaging to ROVs and uncrewed surface vessels - at a fraction of the cost of traditional sonar systems.
Real Acoustic Imaging, Live
These are unedited SonarView captures from Omniscan hardware in the field - no rendering, no post-processing.
Omniscan 450 FS vs. Oculus M750d
Side-by-side with a multibeam imaging sonar costing many times more - the Omniscan holds its own on target definition and range.
Side-Scan and 3D, One Pass - Friday Harbor
An Omniscan 3D 450 SS log replayed in SonarView: the conventional side-scan waterfall on the left, and the geo-referenced 3D surface built from the same returns on the right.

Real-Time 3D Point Cloud
The Omniscan 3D 450 SS paints a dense, live 3D point cloud of the seabed in a single pass - no offline processing step.

The four Omniscans, side by side
Same 450 kHz transducer core on every model. What separates them is beam width, range, how much of the electronics is in the housing - and, on the 3D, whether you get a point cloud.

Side-Scan Sonar for Survey & Search
Side-scan, multibeam or 3D? Which one a small survey USV actually needs →
The Omniscan 450 SS is built for side scan. Its longer transducer geometry buys better along-track resolution and more range - up to 150 m per side.
Specifications

- Maximum range150 m
- Beam width0.5°
- Ping rate, 30 m to 140 m20–5 Hz
- Transducer depth rating300 m

Side-Scan
Compact
Simplified Integration for Small ROVs
The Omniscan 450 Compact puts the transducer, the electronics and a three-port Ethernet switch in one housing, for small ROVs where the sonar bay and the cable run decide what will fit.
Specifications
- Frequency450 kHz
- Maximum range100 m
- Beam width1.1°
- Vertical beam angle10° downward
- Internal Ethernet switchYes

Real-Time 3D Point Cloud Generation
Multibeam or 3D side scan? Which one your survey actually needs →
The Omniscan 3D 450 SS fills the gap between conventional side-scan sonar and a full multibeam echosounder.
Specifications
- Frequency450 kHz
- 2D range, per side150 m
- 3D range, per side100 m
- Receive elements16

3D Imaging
Looking for the Omniscan 3D Upgrade Kit?
The RX16 receive module that converted an existing Omniscan 450 into a 3D system is no longer sold - Cerulean state this in their own documentation. We would rather tell you that here than quote you something we cannot deliver.
The all-in-one Omniscan 3D 450 SS above is the current route to 3D, and Cerulean recommend it over the old modular approach even for people who already own an Omniscan: it needs no extra watertight enclosure, no separate Linux computer, it uses less tether bandwidth because the beamforming happens on the device, and units can be chained through its built-in Ethernet switch.
Your existing Omniscan 450 is not wasted. Run it alongside - two Omniscans at right angles give you side-scan imaging and Doppler motion tracking for position hold with no DVL.
Real Output From Real Dives
Every image below is captured directly in SonarView - the free software included with every Omniscan. This is the data you take home from a survey.
3D structure and classic side-scan - from the same ping
Because the Omniscan 3D measures the vertical angle of every return, SonarView reconstructs the seabed in three dimensions while still giving you the familiar side-scan waterfall. You can spin the point cloud, measure heights, and confirm a target's shape - all from a single recorded pass.
- Resolve the height and shape of wrecks, debris and structure
- Replay, re-colour and re-measure any logged dive offline
- Export point clouds to CSV / GSF for third-party processing
Find it, classify it, then send the ROV
Wide-swath acoustic imaging lets you cover ground fast and pick out anomalies on the seabed long before a camera could see them. Identify the target acoustically, fix its position, and deploy your ROV straight to it - saving hours of blind searching in turbid water.
- Cut through dark, silty and turbid water where cameras fail
- Cover large search areas in a single transit
- Hand off a precise position fix to the recovery vehicle
