See and be seen on the water

AIS is one of the most valuable safety technologies on the water, and em-trak builds quality AIS gear to deliver it. An AIS transponder transmits your boat's position and information to nearby vessels and shows you theirs, dramatically improving collision awareness, especially in traffic, fog, and at night. em-trak offers AIS transponders that both transmit and receive, receivers that show you others, and the antennas, splitters, and accessories to complete an install. By making you visible to other boats and giving you a clear picture of traffic around you, em-trak AIS adds real safety. For boaters who want to see and be seen, it is dependable, well-regarded gear.

Choosing the right product comes down to AIS type and your setup. A transponder both transmits and receives, so you see and are seen, while a receiver only shows you other vessels, so choose a transponder for full two-way awareness. Confirm the unit works with your chartplotter or display, and that you have a proper antenna and GPS, plus an antenna splitter if sharing with a VHF. Register your AIS for an MMSI before transmitting. Review the product details before buying. With em-trak AIS aboard, you add real collision awareness and safety.

Frequently Asked Questions

What is the difference between an AIS transponder and receiver?

An AIS transponder both transmits your position and receives others', so you see and are seen by nearby vessels, while a receiver only shows you other vessels. Choose a transponder for full two-way collision awareness, or a receiver just to see traffic.

Do I need a separate antenna?

AIS needs a VHF-band antenna and a GPS for position. You can use a dedicated AIS antenna, or share your VHF antenna with an antenna splitter. Confirm your antenna and GPS setup, and add a splitter if you want to share one antenna with your VHF radio.

Do I need to register my AIS?

Yes. An AIS transponder transmits your MMSI number, so you must obtain and program an MMSI through the proper authority for your country before transmitting. Register the unit correctly so your boat's information is accurate to other vessels and authorities.
