Next-generation distress beacons: the shift you shouldn’t miss

The technology behind maritime distress alerting has advanced remarkably — from simple analog tones to satellite-connected devices capable of pinpointing emergencies within minutes. Today, another transformation is underway: the development of Second-Generation Beacons (SGBs), designed specifically for the MEOSAR system. For marine radio inspectors and surveyors, understanding this shift is not just interesting — it’s essential for staying compliant and future-ready.... Read more >>

How to ensure GMDSS equipment is truly operational

The Global Maritime Distress and Safety System (GMDSS) is a cornerstone of maritime safety, ensuring that ships can communicate in emergencies and receive critical safety information. However, simply assuming that GMDSS equipment is functional based on a visual inspection or crew confirmation can be a risky approach. Hidden malfunctions may go unnoticed until the equipment is urgently needed. So how can radio inspectors ensure that GMDSS equipment is truly... Read more >>

Apart from a few isolated cases, the system works exceptionally well and is allowing us to more testing on board, with more accuracy, in less time. Along with the generated reports it really makes the reporting extensive and accurate.

Your bt.mini is an excellent piece of test equipment. I ordered it first because I had never dealt with your company before and decided to purchase your least expensive tester. Now, after two years of trouble free service, I am impressed enough that I am "moving up" to a tester with more features. Your shipping response time is outstanding.
