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.
