If you’re heading offshore around the UK or across to Europe, a personal locator beacon isn’t optional extra kit — it’s the single piece of gear that gets rescuers to your exact position if things go wrong. Here’s what we’d recommend and how the options differ.
PLB Comparison
| Device | Type | Price |
|---|---|---|
| ACR ResQLink 400 Personal Locator Beacon PLB | PLB, 406MHz distress | £344.99 |
| ACR ResQLink View PLB-400 GPS Personal Locator Beacon | PLB with digital display | £402.99 |
| Garmin inReach Mini 2 Satellite Communicator | Satellite communicator | £459.99 |
ACR ResQLink 400 Personal Locator Beacon PLB
The ACR ResQLink 400 Personal Locator Beacon PLB transmits on the 406MHz distress frequency straight to the international COSPAS-SARSAT satellite system, which alerts national rescue coordination centres — no subscription required, and it’s covered by ACR’s warranty including the battery. It’s a genuinely essential piece of kit for offshore sailors, anglers and kayakers venturing beyond sight of land.
ACR ResQLink View PLB-400 GPS Personal Locator Beacon
The ACR ResQLink View PLB-400 GPS Personal Locator Beacon adds a digital display that confirms GPS position lock and beacon activation status — useful reassurance in a genuine emergency that the device is working and transmitting correctly.
Garmin inReach Mini 2 Satellite Communicator: Two-Way Communication
Unlike a PLB, the Garmin inReach Mini 2 Satellite Communicator requires a satellite subscription plan but offers two-way text messaging and SOS response coordination beyond a simple distress signal — useful if you want to message home or check weather updates from offshore, not just call for rescue.
PLB vs Satellite Communicator: Which Do You Need?
- PLB (ACR ResQLink): one-way emergency distress only, no subscription, long shelf life — the minimum safety kit for offshore trips.
- Satellite communicator (Garmin inReach): two-way messaging, tracking and SOS, but requires an ongoing subscription plan.
- Many offshore sailors carry both — a PLB as the ultimate no-subscription backup, and an inReach for day-to-day communication and tracking.
Frequently Asked Questions
Do I need to register my PLB?
Yes — in the UK, PLBs must be registered with the relevant authority (via Ofcom/the UK PLB register) so your details are linked to the beacon’s unique ID.
How long does a PLB battery last?
ACR ResQLink beacons are rated for several years of standby life and a minimum of 24 hours of continuous transmission once activated — check the specific model’s battery expiry date.
What else should I carry for offshore safety?
A PLB pairs well with a West Marine Offshore First Aid Kit (£91.99) and a VHF radio — see our VHF radio guide for options.
