NAIS-500 class B AIS with GPS-500 GPS antenna. Broadcast your location to anyone nearby with an AIS Receiver. A low cost safety system for recreational vessels and smaller professional vessels in near coastal waters.

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 compatible MFD display and VHF system.

Key Features

  • Class-B approved
  • Send & receive
  • Integrated solution
  • Multiple networking connections
  • Waterproof IPX7
  • Lightweight - Just 250 grams.
  • Low power consumption
  • Wide voltage range

Class-B Approved

Meets with the strict regulations set out for this class of Automatic Identification System.

Send & Receive

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.
