Ocean Signal rescueME PLB3 AIS review
Sailors, offshore paddlers and remote hillwalkers who want a one-off, no-subscription distress beacon rather than an ongoing messaging service.

A compact, well-built 406MHz PLB with AIS transmission for close-range rescue, backed by Ocean Signal's marine safety reputation. It's a one-way emergency-only device, not a messenger, so it suits people who want distress cover without a recurring bill.

- No subscription — one purchase, no ongoing fees
- AIS transmission helps nearby vessels/aircraft home in during the final rescue stage
- Over 24 hours battery life and a 6-year unreplaced shelf life; small and pocketable
- No two-way messaging, weather, or check-in texts — it only sends an emergency alert, once triggered
- Higher upfront price than basic 406MHz PLBs without AIS
Who shouldn't buy this
You want routine check-in texts or two-way messaging on a trip — a subscription satellite messenger (e.g. Garmin inReach) does that; a PLB is emergency-only and stays silent otherwise.
