  • Overview


    Industry Leader in Testing and Certifications

    Tideland Signal RACONs are the leading industry RACON with all hazardous certifications for:

    • GMU (General Marine Use)
    • NEC Class 1 Division 2
    • IECEx/ATEX Category 2 (Zone 1)
    • IEXEx/ATEX Category 3 (Zone 2)

    Each RACON is available in X band, S band or both and is IP68 rated with testing to withstand 10m water depths for 100 hours.

    Top of the Line Range and Performance

    All RACONS come equipped with high-caliber receiver sensitivity(-50dBm) with higher gain antennas (6dBi) to provide superior range performance with solid state radars, and all Tideland Signal RACONS provide proportional scaling that will produce uniform radar trace on all range settings. User selected quiescent periods, trance length of 4 to 80 microseconds, active periods of 4 to 60 seconds and extended & standard response code can be programed in the field providing remarkable performance and response.

    Advanced Environmental Protection

    Designed to withstand temperatures from -40° C to 70°C with pressurization to protect against corrosive environments, temperature variations, pressure fluctuations, condensation, and submergence; the Tideland Signal RACON is the most durable and longest lasting RACON for your needs.

  • Applications

    The mariner can measure the distance between their vessel and the Racon along with their direction. From that information, and with a local nautical chart, they can accurately determine their position.

    Racons are used to mark dangerous locations such as:

    • Rocks
    • Channel Entrances
    • Peninsulars
    • Sunken Vessels
    • Offshore Platforms
    • Borders and Boundaries
    • Oil Fields
    • Hazardous Areas
    • Military Practice Zones
    • Channels Under Bridges
    • Indistinct Coastlines
