The SIMRAD S3009 is a modern IMO type-approved navigation echo sounder designed for SOLAS vessels, workboats, and merchant ships, providing reliable and accurate under-keel depth measurement for safe navigation.
It is a compact, all-in-one digital echo sounder, widely used on vessels where space, simplicity, and cost-effectiveness are important.
The S3009 operates by:
- Transmitting ultrasonic pulses from a hull-mounted transducer
- Receiving echoes reflected from the seabed
- Calculating depth based on time-of-flight of sound waves
- Displaying:
- Digital depth value
- Echogram (seabed profile)
