Garmin inReach Mini 2
The Garmin inReach Mini 2 is best-in-class for campers and hikers who need two-way satellite communication and an SOS capability in a very compact package. Its global Iridium connectivity and messaging/tracking features give it a clear technical advantage over passive signaling gear on this list, though it carries higher upfront cost and requires an ongoing subscription compared with subscription-free PLBs like the ACR ResQLink. For trips where remote coordination, weather updates and confirmation of rescue are important, its active-communication capability makes it the market leader.

ACR ResQLink View RLS
The ACR ResQLink View RLS is a market-leading personal locator beacon (PLB) that transmits a one-way distress signal with integrated GPS to international search-and-rescue satellites. Unlike satellite communicators it requires no monthly subscription—making it a financially attractive, set-and-forget option—though it lacks the two-way messaging and tracking of the Garmin inReach Mini 2. Its technical strength is a high-power emergency broadcast and simplicity, ideal as a reliable backup to lights, whistles and mirrors.

Princeton Tec Meridian Strobe/Beacon
The Princeton Tec Meridian Strobe/Beacon is a compact, high-output visual strobe designed for low-light signaling and scene illumination while camping or hiking. Technically optimized for long battery life and visibility at night, it is far more affordable than satellite communicators and PLBs but cannot summon rescue services remotely; it pairs well with devices like the Garmin or ACR for full-coverage emergency plans. For users prioritizing night-time visibility and low ongoing cost, the Meridian is a practical and lightweight beacon.

SOL Rescue Flash Signal Mirror
The SOL Rescue Flash Signal Mirror is a lightweight, no-battery visual signaling tool that uses reflected sunlight to attract attention over long distances during daytime. Financially inexpensive and virtually maintenance-free, it provides a long-range daylight advantage compared with strobes and whistles, though it won’t work at night or send an automated distress signal like the ACR PLB or the Garmin communicator. As a compact daylight backup it pairs well with electronic devices to cover multiple signaling scenarios.
