    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.

    • Class B AIS transponders have made a remarkable impact on small craft navigation but many potential users or installers are put off by the requirement for yet another VHF antenna
      • The AIT3000 “Nucleus” Class B transponder changes this with its patented ZeroLoss VHF-AIS antenna splitter
      • It incorporates not only a full function Class B AIS transponder but also an antenna splitter allowing the main VHF antenna on the boat to be shared with the AIS and VHF
    • It's also been designed with the latest interfacing capability including NMEA 0183, NMEA 2000, USB and a WiFi server to integrate with tablets and iPads – hence the name Nucleus as it becomes the hub for on board navigation
    • Today’s boat is all about connectivity
      • The Nucleus offers not only NMEA interfacing but USB for PC and MAC and WiFi for tablets and smartphones
