Em-Trak Marine Electronics

<h3>About Em-Trak Marine Electronics</h3><p>When it comes to on-water safety and situational awareness, few names carry as much weight as <strong>Em-Trak Marine Electronics</strong>. For over two decades, em-trak has focused on a single, critical mission: designing and manufacturing AIS transceivers and integrated marine communication systems that perform flawlessly when it matters most. Trusted by professional mariners, coast guard organizations, search and rescue teams, and recreational boaters around the globe, em-trak has earned its reputation through an unwavering commitment to engineering excellence.</p><h3>A Legacy Built on AIS Technology</h3><p>Em-Trak is a wholly owned subsidiary of UK-based SRT Marine Systems, and that heritage runs deep in every product they build. At the core of each em-trak device is a powerful, fully integrated communication engine refined over more than 20 years of continuous development. This proprietary technology enables real-time processing of AIS transmissions at maximum range while supporting seamless VHF communication &mdash; without loss or error. Whether you are navigating busy shipping lanes, heading offshore, or operating in challenging inland waterways, em-trak keeps you connected, aware, and in control.</p><h3>Class A and Class B AIS Transceivers</h3><p>Em-Trak offers a comprehensive lineup covering both Class A and Class B AIS transponders, making them one of the few brands capable of serving everyone from recreational sailors to SOLAS-certified commercial vessels. The <strong>B-Series</strong> transceivers, including the high-power 5W SOTDMA models, deliver extended range, transmission priority, and ultra-low power consumption in a compact, rugged footprint. The <strong>A-Series</strong>, including the A200, is both SOLAS and inland waterway certified, offering an integrated color display, comprehensive alert systems, and seamless connectivity to ECDIS and bridge systems. For those seeking the ultimate in integrated communication, the <strong>X100</strong> blends VHF, DSC, and AIS technology with intuitive wireless control in a single device.</p><h3>Built to Withstand the Sea</h3><p>Em-Trak engineers every product from the ground up for harsh marine environments. UV-resistant enclosures, marine-grade stainless steel components, high-impact sealing, and vibration protection are standard across the lineup. Every unit manufactured passes through more than 1,000 automated tests and waterproofing checks before it leaves the factory &mdash; and any unit that fails a test is scrapped, not reworked. That zero-compromise manufacturing philosophy is why em-trak products are trusted in the world&apos;s most demanding maritime applications.</p><h3>Connectivity and Compatibility</h3><p>Modern boaters demand flexibility, and em-trak delivers. All transceivers support both NMEA 0183 and NMEA 2000 interfaces, along with Wi-Fi and Bluetooth wireless connectivity, making it straightforward to pair with any chartplotter, mobile app, or onboard display system. Em-Trak transceivers are extensively tested for interoperability with all major marine electronics platforms, ensuring that adding an em-trak unit to an existing setup is a seamless experience rather than a frustrating integration project.</p><h3>Why Choose Em-Trak?</h3><ul><li>Over 20 years of dedicated AIS and VHF technology development</li><li>Class A (SOLAS-certified) and Class B options for every vessel type</li><li>Manufactured in one of Europe&apos;s most advanced electronics facilities</li><li>Rigorously tested: 1,000+ automated checks per unit, zero fault rework policy</li><li>NMEA 0183, NMEA 2000, Wi-Fi, and Bluetooth connectivity as standard</li><li>Trusted by coast guards, search &amp; rescue teams, and commercial operators worldwide</li><li>Backed by a global three-year warranty</li></ul>

Product Details

The Em-Trak 431-0001 is a Class B AIS Transponder designed for recreational and commercial marine vessels. Automatic Identification System (AIS) technology allows your vessel to broadcast its position, speed, course, and identity to nearby ships and shore stations, while simultaneously receiving the same data from other AIS-equipped vessels — significantly improving situational awareness and collision avoidance at sea.

Key Features:

  • Class B SOTDMA AIS transponder for reliable, continuous position broadcasting
  • Dual-channel simultaneous receive on AIS channels 87 and 88
  • Compact, low-profile design suitable for a wide range of vessel installations
  • NMEA 0183 and NMEA 2000 connectivity for integration with chartplotters and MFDs
  • Built-in GPS receiver for standalone operation
  • Low power consumption for extended underway use
  • Complies with ITU-R M.1371, IEC 62287, and applicable FCC/Industry Canada regulations

The Em-Trak 431-0001 integrates seamlessly with major marine navigation systems and is suitable for sailboats, powerboats, and other recreational vessels requiring dependable AIS performance. Its compact footprint and straightforward NMEA connectivity make installation straightforward for both new builds and retrofit applications.
