The SI-TEX MDA-6 delivers Class-A—level transmit priority, rapid update rates, and 5-watt SOTDMA transmission—more than twice the power of standard Class B AIS units. Your vessel is detected earlier and at greater distances, even in demanding or congested waterways

The MDA-6 broadcasts continuous dynamic data including SOG, COG, heading, and hazard reports, giving surrounding vessels a clearer, more accurate picture of your movements.

The MDA-6 is engineered for reliability in real-world conditions. Its IP67-rated housing protects against water, dust, and vibration, while its compact footprint allows flexible installation on any vessel.
