In this video, I review the ACR / Ocean Signal rescueME PLB1 personal locator beacon, a critical piece of safety gear for backcountry hiking. I walk through exactly how to use the PLB1—from deploying the antenna to activating a rescue signal—and explain what happens behind the scenes with the satellite system once you hit the distress button. It’s simple to use and designed for those times when you’re out of cell range and need serious help.

I also break down how this PLB compares to two-way satellite communicators like the Garmin inReach and Zoleo. The PLB1 doesn’t require a subscription and runs on a sealed battery that lasts up to seven years, making it a great low-maintenance option to throw in your pack and forget about—until you need it. I share how I use mine alongside an inReach for redundancy and explain when each might be the better choice.

We also dive into the Cospas-Sarsat system that powers the PLB’s rescue alerts, how rescue coordination works through Air Force or Coast Guard centers, and why registering your device is not just smart but required by law. I also touch on the tech specs, including GPS functionality, signal strength, and the PLB1’s built-in strobe and homing beacon features that help rescuers zero in on your location.

This review is based on my hands-on use of the PLB1 and real-world experience with different safety setups. I cover everything you need to know if you’re thinking about adding a PLB to your kit—or wondering if it’s the right fit over a satellite communicator.
