    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.

    This powerful Class B/SO* AIS transceiver will make your boat "visible" to other vessels with AIS over long disances and in challenging conditions with its 5-watt transmission power. The SI-TEX Metadata MDA-5 module transmits at more than twice the power of traditional Class B AIS transceivers to put you on more screens for increased safety.

    *SOTDMA stands for Self-Organized Time-Division Multiple Access and means as AIS info comes into the receiver, it organizes the data into time slots that are time-shared with a TDMA receiver. It transmits at 5W at high power, twice the power of traditional Class B AIS Transceivers — so your boat can be "seen" over long distances and in the most challenging conditions.
