Navigating crowded waterways demands vigilance, and the NAIS-500 Class B AIS transponder bundle elevates your boating safety to professional levels. This complete kit, featuring the compact NAIS-500 transceiver, GPS-500 antenna, and NSPL-500 splitter, lets you broadcast your vessel's position, speed, and course while receiving real-time data from nearby ships. Whether dodging commercial traffic in busy harbors or threading through recreational fleets, this setup gives you the edge to spot risks early and maneuver confidently.
Unlike basic radar or visual spotting, AIS provides precise, automated collision avoidance. The Class B certification ensures compliance with international standards, making it a staple for serious boaters. Its low-profile design slips easily into tight console spaces, drawing minimal power to preserve your battery life during long outings. Pair it seamlessly with Simrad chartplotters like NSS, NSO, or GO series, and integrate with RS VHF radios for a unified network that displays targets right on your screen.
The heart of this bundle's convenience is the NSPL-500, a featherweight (just 260 grams) performer that multiplexes signals with negligible loss. VHF transmissions punch through clearly on transmit, while receive paths stay crystal-clear for AIS pings and radio comms. Plug-and-play FM output hooks right into SonicHub or any stereo, keeping your music flowing alongside safety data. Low draw under 150mA means it won't strain solar setups or engines-off anchoring.
Round out the system with the GPS-500, delivering accurate location fixes to feed your AIS transmissions. Mount it high and clear for optimal satellite lock, ensuring your reported position is spot-on for safe separations.
Multiple interfaces—NMEA 2000 backbone, NMEA 0183 multiplexing, and USB for PC logging—make integration a breeze. Drop it into your existing network with the included Micro-C T-connector and 6-foot extension cable. Boaters report setups taking under an hour, with no special tools beyond basic wiring. For U.S. users, professional programming aligns it with FCC rules using your MMSI, keeping everything legal and operational from day one.
Tested to IEC 60945 protected standards, this kit thrives in salt spray, vibrations, and temperature swings. Low power sipping (180mA average at 12V) supports extended voyages, while the 2-year warranty backs your investment. Sailors and powerboaters alike praise its stability in choppy conditions, where lesser units falter.
Class B is tailored for recreational and smaller commercial vessels like yours. It transmits less frequently than Class A's high-power signals but prioritizes essential data like position and course, making it cost-effective and sufficient for most pleasure boating needs.
No noticeable degradation—it's engineered for zero insertion loss on receive and minimal on transmit, preserving your VHF range and AIS sensitivity across shared channels.
Yes, thanks to universal NMEA 2000 and 0183 support. It works with most modern marine MFDs from brands like Garmin, Raymarine, and Lowrance, as long as they handle AIS data.
Aim for a high, unobstructed spot like a masthead or rail. Use marine-grade mounts to avoid interference from metal surfaces, ensuring reliable GPS signals for accurate AIS reporting.
Around 180mA at 12V for the NAIS-500, plus under 150mA for the splitter—total draw stays low, ideal for battery banks on sailboats or weekend cruisers.
Yes, link it to your existing VHF MMSI. In the U.S., certified programming is required; provide your registration for hassle-free setup.
Equip your boat with this all-in-one AIS solution and sail smarter, safer. Boaters who add AIS report fewer close calls and more peace of mind on the water.
Reduce your risk of collision with this fully integrated, Class-B AIS transponder: essential for navigating today's busy shipping lanes and congested ports. Compact in size, lightweight, fully waterproof, with low power draw and featuring multiple connections, the NAIS 500 is ideal for networking with any NSS, NSO or GO series chartplotter or multifunction display and Simrad RS VHF system. Meets with the strict regulations set out for this class of Automatic Identification System. The NAIS 500 ensures that you are seen and can see on the water by sending a signal to other vessels with your navigational data, whilst you receive data from other vessels. This allows you to plan any necessary avoidance manoeuvres well in advance.
**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.**
