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 Mosaic — Friday Harbor
An Omniscan 450 SS builds a continuous geo-referenced acoustic mosaic of a harbour floor as the vehicle transits.
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.
Omniscan 450 Models
Choose the variant that best matches your vehicle, mission, and budget. All models share the same 450 kHz transducer core and are supported by SonarView software.
Forward-Looking
Forward-Looking Sonar for ROV Navigation
The Omniscan 450 FS puts scanning control directly in the hands of the ROV pilot. The transducer and electronics are housed in a single compact enclosure with a combined Ethernet + power interface. With a 50° vertical beam, the FS provides both forward and downward visibility — ideal for wreck hunting, navigation, and object detection out to 120 m.
For ROVs without a DVL, pairing two FS units (one forward, one offset 90°) enables 2D Doppler motion tracking and position-hold capability directly in SonarView.
- 120 m detection range; 0.8° beam width
- 50° vertical beam — forward & downward coverage
- Single cable: Ethernet + power combined
- Compatible with QYSEA FIFISH E-Go, W6, and Blue Robotics platforms
- Doppler mode for position-hold without DVL

Side-Scan Sonar for Survey & Search
The Omniscan 450 SS is optimized for side-scan applications. Its longer transducer geometry delivers better along-track resolution and extended range — up to 150 m per side. To scan simultaneously on both sides, two units are deployed — one to port, one to starboard.
The electronics are on a separate PCBA, enabling flexible mounting in a vehicle housing of your choice. Ideal for USV-based survey, search & recovery, and pipeline inspection.
- 150 m range; 0.5° narrow beam width for high resolution
- 50° beam height optimized for wide swath coverage
- Separate electronics PCBA for flexible housing integration
- Dual-unit configuration for simultaneous port & starboard scanning
- Available in BlueBoat-specific variant

Side-Scan
Compact
Simplified Integration for Small ROVs
The Omniscan 450 Compact packs all electronics and the transducer into a single enclosure — perfect for small ROVs where space and cable management matter. A built-in 3-port Ethernet switch allows up to two additional Ethernet devices (e.g., a camera or second sonar) to be daisy-chained from a single tether connection.
The 10° downward beam angle provides optimal coverage of the seafloor ahead of the vehicle, making it especially suitable for bottom-following navigation and structure inspection.
- All-in-one form factor — transducer & electronics integrated
- Internal 3-port Ethernet switch for daisy-chaining devices
- 10° downward vertical beam for optimized bottom coverage
- 100 m max range; 1.1° beam width
- 300 m depth rated; 934 g air / 400 g water

Real-Time 3D Point Cloud Generation
The Omniscan 3D 450 SS is an advanced underwater imaging system that fills the gap between conventional side-scan sonar and full multibeam echo sounders. Using a 16-channel receive array, it calculates the vertical angle of every acoustic return — generating high-resolution 3D point clouds of the seafloor in real time at 450 kHz.
The result is dense bathymetric data with wide-swath coverage and the workflow simplicity of a side-scan sonar, at a fraction of the cost of a traditional multibeam system.
- 16-channel receive array for vertical angle calculation
- Real-time 3D point cloud — no post-processing required
- Wide-swath bathymetric data capture in a single pass
- 450 kHz for high along-track resolution
- Supported by SonarView with CSV and GSF export

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
