Frequently Asked Questions (FAQs)

  • 1. What is an echo sounder?
    An echo sounder measures the depth of water beneath the ship using sound waves. It’s vital for safe navigation and grounding prevention.
  • 2. Is it mandatory under SOLAS?
    Yes. Echo sounders are mandatory on most SOLAS vessels for safety of navigation, especially in coastal and shallow waters.
  • 3. Which frequencies are used?
    Echo sounders typically operate on dual frequencies: 50kHz for deep water and 200kHz for shallow waters.
  • 4. Can I integrate it with ECDIS or VDR?
    Yes. Modern echo sounders provide NMEA or analog output that can be connected to ECDIS, VDR, and other bridge systems.
  • 5. What is a transducer?
    It’s the component installed on the ship’s hull that sends and receives acoustic pulses. It’s critical for accurate depth readings.
  • 6. Do you supply echo sounders?
    Yes. We supply, install, and support top brands like Furuno, JRC, Navis, Skipper, and more.
  • 7. How is calibration done?
    Calibration is done using reference soundings or a known charted depth, adjusting display offset to match actual water depth.
  • 8. What is “depth below keel” mode?
    It shows the depth from the ship’s keel to the sea floor, commonly used to avoid grounding risks.
  • 9. Do you offer fault repair services?
    Yes. We troubleshoot faults like signal drop, no display, or incorrect depth reading onboard and in workshop.
  • 10. Where do you offer service?
    SEANAV provides service across India, UAE, Singapore, Egypt, Qatar, Oman, and Bahrain with certified marine engineers.
