Ocean Signal rescueME PLB1 review
Hillwalkers, sailors and remote travellers who want serious emergency-only cover with no ongoing subscription to remember.
By Tom Calder · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
A well-made, genuinely pocket-sized PLB that does one job — get a real search-and-rescue team to your GPS position — without a monthly bill. It has no messaging or check-in features, so pair it with a plan for someone at home to know your route.

- No subscription ever — one registration, then it's free to use for the life of the unit
- One of the smallest, lightest PLBs on the market (77 x 51 x 32.5mm, 116g) — easy to actually carry
- Dual 406MHz satellite alert + 121.5MHz homing signal plus built-in GPS and a strobe for search teams
- SOS-only — no two-way texting, no 'I'm OK' check-ins, no weather; you can't tell anyone you're fine, only that you're not
- Battery isn't user-serviceable — needs an authorised centre, and the 5-year warranty only applies if you register it
Who shouldn't buy this
You want to send routine check-in messages or track a route for family to see — that needs a two-way satellite messenger with a subscription, not a PLB; the PLB1 only has one function, a genuine SOS.
