Nauticast AIS Class A Transponder

Service, upgrade and repair for one of the most widely used class A transponders ever







We offer convenient upgrade solutions from your AIS model to the new Nauticast A2!

This device belongs to a small group of real workhorses in the international maritime industry. It was manufactured for a period of more than 10 years with several updates, improvements and technical developments.

The devices were sold under a variety of brand names and appearances, including several different layouts and colours for the front panel keyboard: Examples are X-Pack (DS/US), X-Base, GlobalWatch, Bridgemate and others.

Nauticast still offers service, repair and upgrade for all units. Please refer to the product sheet below or go to our Service Centre for more information.

  • Specific upgrade sets that connect all existing cables directly to the new Nauticast A2 (data/sensor, GPS, VHF; with or without a connection box installed).; and
  • a special flush-mount frame for those who want to install the new Nauticast A2 in the same position as the current AIS. Please check the amount of space behind the panel before picking this option!
