The Omniscan 450 SS is tailored for side-scan applications. It has a longer transducer which gives 50% better angular resolution and 150m maximum range.

For scanning both sides simultaneously, order quantity 2. SonarView integrates both devices together as if they were a single system.

As the ROV or surface vessel moves, SonarView “paints” the image of the scanned area of the sea floor giving excellent situational awareness in the murkiest conditions.

In the case of a surface vessel with GPS or an ROV with DVL, scanning is translational as well as rotational. A key feature of the Omniscan 450 is its integration via SonarView with the vehicle's MAVLINK data stream. Using the vehicle's attitude and location information, SonarView displays each ping in its correct absolute orientation and position.

Side Scanning

The Omniscan 450 SS transducer is rated to 300m operating depth. Two units of the Omniscan 450 SS can be combined in SonarView for the conventional side-scan application in which both sides are scanned simultaneously.

The electronics module must be mounted in the vehicle’s water tight enclosure.

Electrical Connection

Single cable with 4 pin JST for data (Blue Robotics Ethernet standard), plus a wire pair for power. Adapter provided for standard RJ-45 ethernet connection.

Maximum Range


Far Field (Note 1)


Beam Width (Note 2)

0.5 degress

Beam Height

50 degress

Maximum Operating Depth

Overall Dimmensions


Note 1: Far Field distance is the range beyond which the beam width specification is valid. At nearer distances the effective beam width gets wider, and sidelobes get larger. Note 2: This is the nominal theoretical 2-way (transmit and receive) 3dB beam width.
