Description
Sponsored by GME – but as always, I'll tell you what I actually think.
In this video, I compare the new GME MT620GR with the MT610G Personal Locator Beacon (PLB). I break down the real differences: GNSS vs GPS, Return Link Service (RLS), NFC app connectivity, and whether the upgrade is worth your money. I also explain why your Garmin InReach Mini or iPhone satellite SOS – as useful as they are – don't replace a dedicated PLB. And for those wondering about EPIRBs on land: short answer, don't.
I've been carrying GME PLBs for over a decade (my first one still passes a self-test 10 years past expiry – make of that what you will). As someone who spends serious time in remote Australia, I share my honest take on which beacon suits which situation.

Key Differences – MT620GR vs MT610G:
• Multi-GNSS (GPS + Galileo) vs GPS only
• Position fix: ~30 sec vs 45–60 sec
• Accuracy: ~45m vs ~100m
• RLS confirmation (blue LED) – know help is coming
• NFC + AcuSat Connect app with test logging
• Audible buzzer on activation
• Same weight (160g), same IP68, same 7-year battery, same 2-step activation
• Both made in Sydney by GME (manufacturing beacons since 1979)
Why a PLB still matters:
• 5W transmission vs ~1.6W (InReach/iPhone)
• 121.5 MHz homing signal for SAR direction finding
• COSPAS-SARSAT network – no subscription, no account needed
• Two-step activation with one hand
