The MRT sMRT ALERT is a marine-rated, Class M compliant AIS/DSC man overboard beacon designed to speed up MOB recovery when sailing in Ireland, whether you’re offshore, inshore, or crossing busy shipping lanes.
Once armed, it can activate automatically on immersion and immediately broadcasts a VHF DSC distress alert, then continuously transmits AIS position updates so nearby vessels can track you accurately on their plotter.
Dual GNSS (GPS + Galileo), a powerful strobe, and rugged waterproof protection (IP68 to 10m) make it a dependable choice for harsh Atlantic weather and cold-water conditions.
With NFC app checks and simple lifejacket integration, it’s a practical upgrade for anyone who wants reliable MOB safety equipment without complicated fitting.
