Navigating busy waterways demands equipment that keeps you visible and informed, no matter the conditions. The Simrad V3100 Class B AIS transponder steps up with advanced SOTDMA technology—borrowed from high-end Class A systems—delivering transmissions that punch through crowded channels and reach farther than ever. Boaters and commercial operators alike rely on this black-box powerhouse for its ability to dynamically adjust update rates based on your vessel's speed and surrounding traffic, ensuring your position broadcasts reliably when it counts most.
Imagine cruising through high-traffic zones like coastal shipping lanes or popular harbors: standard Class B units might struggle with infrequent updates and shorter range. The V3100 changes that, transmitting up to six times more often—at intervals as quick as every five seconds—and with 5 watts of output power for detection over extended distances. This isn't just about compliance; it's about enhancing safety through real-time data sharing with nearby vessels, shore stations, and even satellite receivers.
SOTDMA (Self-Organizing Time Division Multiple Access) is the secret sauce here. Unlike basic Class B systems that listen before transmitting (CSTDMA), SOTDMA lets the V3100 negotiate dedicated time slots with other AIS units in the vicinity. The result? Consistent, prioritized broadcasts that cut through the noise of busy areas, providing peace of mind during peak boating seasons or commercial routes.
For vessels operating beyond line-of-sight or in regions with satellite AIS coverage, this boosted range means your boat stays on the map longer, aiding search-and-rescue if needed.
Designed as a rugged black-box unit, the V3100 slips effortlessly into your existing marine electronics ecosystem. Its IP67-rated housing shrugs off saltwater spray and harsh weather, while multiple connectivity options make setup straightforward for DIY enthusiasts or pros.
Pair it with the included GPS-500 antenna for precise positioning right out of the box. Whether you're upgrading a weekend cruiser or outfitting a workboat, this transponder networks without drama, overlaying AIS targets directly on your screens for intuitive collision avoidance.
For U.S. buyers, FCC regulations mandate professional programming by a certified technician. You'll need to provide your MMSI registration or FCC Ship Station License, plus a signed form from the vessel master or owner. This ensures your unit is legally tuned and ready to transmit your unique identifier.
Once installed, enjoy hassle-free operation—but note that this specialized marine product requires direct manufacturer support for any service needs, as it's not eligible for returns to the point of purchase.
Beyond specs, the V3100 empowers smarter decisions. Receive detailed info on nearby vessels—their speed, course, destination, and more—directly on your displays. In fog, night runs, or congested anchorages, this data turns potential hazards into manageable blips. Commercial skippers appreciate the logging for compliance audits, while recreational users love the confidence boost for family outings.
Invest in gear that grows with your boating lifestyle: from coastal hops to offshore adventures, the V3100 delivers pro-level performance without the Class A price tag.
SOTDMA self-organizes transmission slots among nearby AIS units, enabling more frequent updates (up to every 5 seconds) and higher reliability in crowded areas, mimicking Class A performance.
With 5 watts of power—2.5 times standard Class B—it reaches greater distances to other vessels, shore stations, and satellites, improving detection in open water.
It offers NMEA 2000®, dual NMEA 0183®, and USB interfaces, plus an SD card slot for data logging, for broad compatibility with displays, PCs, and networks.
Yes, FCC rules require technician programming with your MMSI or license details and owner signature for legal operation.
Yes, it comes with the GPS-500 antenna for immediate GPS and AIS signal reception.
IP67-rated housing ensures dust-tight and waterproof performance, ideal for marine environments.
It dynamically scales based on vessel speed and local AIS traffic, optimizing for efficiency and reliability.
**As the FCC requires all units sold in the US to be programmed by a qualified technician. Please submit the form below for programming at time of purchase. A copy of the MMSI registration or FCC Ship Station License is required along with the vessel master or owner's signature on the completed programming form.**
V3100 Class B AIS
The V3100 Class B AIS incorporates SOTDMA technology and increased transmission power to enhance transmission frequency, reliability, and range compared to standard Class B AIS. This ‘black-box’ solution integrates with Simrad displays, and features industry-standard connectivity.
Increased Transmission Frequency and Reliability
The V3100 Class B AIS incorporates the same SOTDMA technology found in Class A solutions. This self-organising 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, 2.5 times the transmission power of standard Class B AIS solutions. This allows vessels equipped with the V3100 to be detected over 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.
