StarFish 453 OEM Sidescan System

The StarFish 453OEM system comprises two self contained transducer elements and the StarFish electronics circuit board, allowing Original Equipment Manufacturers (OEM’s) to add sonar capabilities to their own products.


  • Seperate hull mounted transducers.
  • 0.5° horizontal beam width for high resolution imaging.
  • Small electronics footprint (165mm x 100mm x 23mm).
  • Simple USB data connection.
  • Operational depth rating up to 300m.

Outstanding Performance

Built on the proven StarFish digital CHIRP acoustic technology developed from the professional underwater survey industry, the StarFish453 OEM system features an enhanced transducer design with larger acoustic aperture for a 0.5° horizontal beam width (our highest resolution 450kHz sonar), and depth rating up to 300m (980ft) – producing crisper and cleaner imagery at ranges of up to 100 metres on each channel (200m total swathe coverage).

Simple Integration

In addition to the two transducer connectors, the electronics board only requires a power supply (from 9 to 28V DC) and a USB data connection to the controlling PC.

In additional to integration with our Scanline software package, a Software Development Kit (SDK), Windows DLL library and diagnostic toolkit are provided to assist developers integrate the sonar into their systems.
