Personal Locator Beacons (2026)

A personal locator beacon is a 406 MHz radio that talks to COSPAS-SARSAT when you are dying or lost. No subscription. One job. It is not an inReach. It is not a phone. It is not a $30 “personal alarm.” If it does not register with NOAA, it is not a PLB. In 2026 the Amazon units that still make sense are ACR ResQLink (Plus and View) and McMurdo FastFind 220 — in date, registered, carried where they can see sky.

Short version. Buy ACR ResQLink+ or ResQLink View if you want the US name people know. Buy McMurdo FastFind 220 if that is the unit you found and the battery is in date. Register it. Carry it. Know the test button from the live button. Pair with water and a kit that keeps you alive until rescue arrives. Check live prices. We do not invent numbers.

Hiking alone without a PLB or a messenger is a choice you should say out loud. A phone talks to a tower. In a canyon with no tower, a phone is a thin flashlight.

PLB vs messenger vs a phone with a prayer

A PLB is the doorbell to the sky. An inReach-style messenger talks to Iridium, two-way, weather, check-ins, and it bills you every month. A phone talks to a tower. Buy a PLB if you want the rescue button without a plan. Buy a messenger if you also want to text a spouse that you are late. Buy both if you hunt or hike places that eat people. Do not mix the jobs with a tracker that is not 406 MHz.

ACR ResQLink and McMurdo FastFind — the doorbells

ResQLink+ is the orange ACR people have carried for a decade: GPS, 406 and 121.5, a strobe, a unit you register and forget until you need it. ResQLink View adds a screen so you can see a GPS fix instead of trusting a light. McMurdo FastFind 220 is the other COSPAS-SARSAT brick — same job, different badge. In date. Registered. Accessible. Not in a truck console while you walk a ridge.

Registration is the product. NOAA, your name, emergency contacts who will answer at 2 a.m. An unregistered PLB still may go out. A registered one goes out with a person who can say which trailhead you used. Do not live-alert because you were curious. Use the test function the manual describes. A false alert still launches people.

LifeStraw and Sawyer Mini — until they arrive

A PLB is the doorbell. You still have to live. Water, insulation, a way to stay found. LifeStraw is the drink-from-the-creek filter. Sawyer Mini is the squeeze-bag filter that lives in a pocket kit. Neither replaces a beacon. Both replace a night of giardia while you wait. Shelter if you can. Antenna up. On. Leave it on.

Item	Best job	Subscription	Watch-out
ACR ResQLink+	406 MHz rescue button	None	Register it, date the battery
ACR ResQLink View	Same job, screen for a GPS fix	None	Still needs sky
McMurdo FastFind 220	Same doorbell, other badge	None	In-date battery or it is a brick
LifeStraw	Drink until rescue	—	Not a beacon
Sawyer Mini	Pocket filter	—	Not a beacon

Our pick: ResQLink (Plus or View) if you want the US name. FastFind if that is the in-date unit you found. Register it. Carry it. A messenger if you also want two-way. A filter in the same kit. Check live prices. We do not invent numbers. In the mountains that eat people, the PLB is the one that still works when the rest of the kit is a story.

PLB vs inReach vs a phone with a prayer

A PLB (McMurdo FastFind, ACR ResQLink, ResQLink 400 View) talks to COSPAS-SARSAT. No subscription. One job: you are dying or lost and you need rescue. An inReach-style messenger talks to Iridium, two-way, weather, check-ins, and it bills you every month. A phone talks to a tower. In a canyon with no tower, a phone is a thin flashlight. Hiking alone without a PLB or a messenger is a choice you should say out loud.

Buy a PLB if you want the rescue button without a plan. Buy a messenger if you also want to text a spouse that you are late. Buy both if you hunt or hike places that eat people. Do not buy a $30 “personal alarm” and call it a PLB. If it does not register with NOAA, it is not a PLB.

Registration is the product. NOAA, your name, your emergency contacts who will answer at 2 a.m. An unregistered PLB still may go out. A registered one goes out with your medical notes and a person who can say which trailhead you used. Register. Update it when you move. The 406 MHz signal is the point. The 121.5 homing signal is how the helicopter finishes.

How you actually fire one without making it worse

Stop. Shelter if you can. Antenna up, clear view of sky. On. Leave it on. Do not test-fire it on a trail because you were curious. Use the test function the manual describes. A false alert still launches people. Those people have jobs. A survival kit keeps you alive until they arrive. A PLB is the doorbell. Water, insulation, a way to stay found. Water still matters if rescue is a night away.

View screens (ResQLink 400 View) tell you the thing has a GPS fix. Without a screen you trust the light. Read the manual at home. A PLB in a buried pack pocket under a rain cover is a PLB that cannot see satellites. Accessible. Dry. Known to your partner. If you hunt, tell the people who would miss you which pack it is in.

Batteries are dated. Replace them per the maker, not when you remember. A 10-year-old PLB in a glove box is a paperweight. Check the date when you check smoke-alarm batteries. Check live prices. We do not invent numbers.

What a PLB is not, and when it is done

Not a tracker for your kid’s commute. Not a car GPS. Not a reason to skip a map and a plan. Trackers without fees are a different product, usually not a 406 MHz beacon. Do not mix the jobs. A PLB does not tell Instagram where you are. It tells rescue.

Done: expired battery, cracked antenna, a unit that fails the self-test, a registration you never finished. Replace or service. ACR and McMurdo have service programs. Use them. A beacon you “might get around to registering” is not a beacon. It is a paperweight with a strobe.

Our pick: ACR ResQLink (Plus or 400 View) if you want the US name people know. McMurdo FastFind if that is the unit you found and it is in date. Register it. Carry it. Know the test button from the live button. A messenger if you also want two-way. A phone if you have towers. In the mountains that eat people, the PLB is the one that still works when the rest of the kit is a story. Helmets, PFD, ice — different pages. This one is the doorbell to the sky.

Registration is the product. The plastic is the radio

NOAA. Your name. Emergency contacts who will answer at 2 a.m. Medical notes if they matter. An unregistered PLB still may go out. A registered one goes out with a person who can say which trailhead you used. Register. Update it when you move. The 406 MHz signal is the point. The 121.5 homing signal is how the helicopter finishes.

Until they arrive, you still have to live

Stop. Shelter if you can. Antenna up, clear view of sky. On. Leave it on. A survival kit keeps you alive until they arrive. A PLB is the doorbell. Water, insulation, a way to stay found. A filter still matters if rescue is a night away. LifeStraw or Sawyer Mini in the same pocket-kit as the beacon is not a catalog upsell. It is the night.

View screens (ResQLink View) tell you the thing has a GPS fix. Without a screen you trust the light. If you hunt, tell the people who would miss you which pack it is in. A beacon in a truck console while you walk a ridge is a beacon that will not help you.

The pocket check before you leave the truck

Beacon. Filter. Insulation. A way to stay found. Antenna not crushed under a rain cover. Contacts who will answer. That is the pocket check. A PLB in a glove box while you walk is a paperweight. A PLB you never registered is a radio with no name. Do the check. Then hike. Check live prices. We do not invent numbers.
