Garmin inReach Mini 2. Best Overall
The inReach Mini 2 is what lives in my pack lid. It uses the Iridium network for global coverage, sends and receives two-way messages, and the SOS button is connected to Garmin's 24/7 rescue coordination center. Battery life is rated up to 14 days in 10-minute tracking mode. It weighs 3.5 oz.

I have carried a personal locator beacon in the lid of my pack since a friend slipped on a wet slab and nearly went over an edge. We had cell service that day, barely. but I have been on plenty of trails with zero bars and the wrong consequence one step away. After two years of research and comparing, here are the five PLBs and satellite messengers I would actually pack into the backcountry.
A note: “EPIRB” technically refers to marine emergency beacons. For hiking, the equivalent device is called a PLB or a satellite messenger. I am covering both in this guide because hikers searching for an “EPIRB for hiking” almost always want one of these.

Garmin inReach Mini 2. Best Overall
The inReach Mini 2 is what lives in my pack lid. It uses the Iridium network for global coverage, sends and receives two-way messages, and the SOS button is connected to Garmin's 24/7 rescue coordination center. Battery life is rated up to 14 days in 10-minute tracking mode. It weighs 3.5 oz.
ACR ResQLink View PLB. Best Pure SOS
If you do not want a subscription, the ACR ResQLink View is the PLB to get. It transmits a 406 MHz distress signal to the COSPAS-SARSAT system, has a digital display that shows operating status, and the battery lasts 28+ hours of transmission once activated. Once you register it (free with NOAA), there is no monthly cost.
Garmin inReach Messenger. Best Budget Two-Way
The inReach Messenger is Garmin's lower-cost two-way satellite messenger. It does not have a built-in navigation display like the Mini 2, but you pair it with your phone for full functionality. Battery is excellent at up to 28 days in default tracking mode.
Ocean Signal rescueME PLB1. Smallest PLB
The Ocean Signal PLB1 is genuinely tiny. about the size of a deck of cards. and weighs only 4.1 oz. It is a pure PLB with no subscription, broadcasting on 406 MHz with seven years of battery life in standby and 24+ hours once activated. I clip mine to a chest strap for fastpacking trips where every gram counts.
SPOT X. Best Standalone Two-Way
The SPOT X is the only satellite messenger in this group with a built-in QWERTY keyboard, so you can send messages without pairing to a phone. Coverage uses the Globalstar network. The subscription is generally cheaper than Garmin's inReach plans.
Common questions
A PLB sends an SOS only. it has no two-way messaging. A satellite messenger like the Garmin inReach lets you text, share location, and request help via two-way communication, usually with a monthly subscription.
Yes. Registration with NOAA in the U.S. is free, mandatory, and takes ten minutes. Without it, search and rescue cannot tie a distress signal to you.
