    Important Information Regarding the Purchase of a Class B AIS:
    When you are ready to place your order, you will need to complete the AIS Static Data Programming Log.

    This required form must be sent to Defender Industries via e-mail or faxed along with a copy of your MMSI registration before your order can be processed. Our fax number is 860-701-3432.

    Because each transponder can only be programmed once with your personal MMSI number, orders CAN NOT BE CANCELLED AND ARE NOT RETURNABLE after orders have been placed.

    Package Includes:

    • Simrad V3100 Class B AIS
    • GPS-500: GPS antenna

    The Simrad V3100 Class B AIS is designed to meet the needs of vessels operating in high-traffic areas. It incorporates SOTDMA technology and increased output power to provide improved transmission reliability and range in a cost-effective package for vessels that require greater performance than standard Class B AIS, but do not require a full Class A solution.

    Increased Transmission Frequency and Reliability: The V3100 Class B AIS incorporates the same SOTDMA technology found in Class A solutions. This self-organizing transmission technology allows the system to negotiate a regular transmission timeslot with other AIS units in range, facilitating more frequent and reliable position updates in high-traffic areas. The V3100 transmits updates, based on vessel speed, up to once every five seconds; this provides up to six times the reporting frequency of standard Class B AIS.

    Increased Transmission Range: The V3100 features a maximum transmission power of 5 Watts, which is 2.5 times the transmission power of standard Class B AIS solutions. This allows vessels equipped with the V3100 to be detected over standard Class B AIS at a greater range, and provides more reliable transmission to satellite-based AIS receivers.

    Integrated 'Black-Box' Solution: This 'black box' AIS solution is designed to work with Simrad multifunction displays, and other NMEA 2000® or NMEA 0183® connected marine electronics. Output to a standard PC is also supported via USB connectivity. The V3100 is contained in a compact IP67 water-resistant housing, and includes a built-in SD card slot for standalone AIS data logging.
