Why a PLB is Non-Negotiable for Offshore Sailing
When you’re truly offshore, you’ve sailed off the edge of the conventional communications map. VHF radio has a limited range, and cell service is a distant memory. A Personal Locator Beacon (PLB) is your direct link to the Cospas-Sarsat international satellite system, a global network dedicated to detecting and locating distress signals. When you activate a PLB, it sends a unique coded message with your precise GPS location to a ground station, which then forwards it to the appropriate search and rescue (SAR) authorities.
Many boats are equipped with an EPIRB (Emergency Position Indicating Radio Beacon), and they absolutely should be. But an EPIRB is registered to the vessel. If you are separated from your boat—a very real man-overboard scenario—or forced to abandon ship into a life raft, the EPIRB does you no good. A PLB is registered to you. It’s your personal safety net, ensuring that even if you’re alone in the water, the rescue is coming for you, not just your boat’s last known position.
Think of it this way: the EPIRB is for saving the ship, but the PLB is for saving the sailor. For any remote expedition, having both is the gold standard of safety. It’s a small, lightweight piece of insurance that provides an unparalleled level of security when you’re days from the nearest help.
ACR ResQLink 410 RLS for Two-Way SOS Confirmation
You’re in a life raft, soaked and cold, having just activated your beacon. The biggest question hammering your mind is, "Did it work? Does anyone know I’m here?" The ACR ResQLink 410 RLS directly answers that question. Its standout feature is Return Link Service (RLS), which provides a confirmation signal—a flashing blue light—letting you know that the distress network has received your message. In a high-stress survival situation, that small confirmation is an immeasurable psychological boost.
Beyond RLS, the ResQLink 410 is a purpose-built marine survival tool. It’s inherently buoyant, so you don’t have to worry about it sinking if dropped. It utilizes both GPS and the Galileo satellite networks for faster, more accurate positioning and includes both a standard and an infrared strobe light, making you more visible to rescuers day or night, and with night-vision equipment.
This device is a pure, dedicated lifesaver. There is no two-way messaging or tracking. Its sole purpose is to send a powerful, reliable SOS signal and confirm its receipt. If your top priority is a simple, foolproof emergency beacon with the peace of mind of confirmation, the ResQLink 410 RLS is an outstanding choice.
Ocean Signal rescueME PLB1: The Ultimate Compact Beacon
For the sailor who believes the best safety gear is the gear you always have on you, the Ocean Signal rescueME PLB1 is hard to beat. It is astonishingly small and lightweight, engineered to be seamlessly integrated into a life jacket or clipped to a belt without you even noticing it’s there. This minimal footprint dramatically increases the odds that it will be on your person during an emergency, not stowed in a ditch bag you couldn’t reach.
Despite its size, the PLB1 doesn’t compromise on core performance. It features a simple, one-handed activation with a protective cover to prevent false alarms and a retractable antenna that deploys easily. With a 7-year battery life and a 7-year warranty, it’s a low-maintenance device you can trust for the long haul.
The tradeoff here is a focus on minimalism. It lacks the buoyancy of larger models (though it comes with a flotation pouch) and doesn’t offer advanced features like RLS. But for many offshore sailors, especially those on smaller, faster boats where space and weight are at a premium, its "wear it and forget it" design is its greatest strength.
Garmin inReach Mini 2 for Two-Way Satellite Messaging
Stay connected anywhere with the Garmin inReach Mini 2. This compact satellite communicator offers two-way messaging, interactive SOS, and TracBack routing for peace of mind on any adventure.
What if your emergency isn’t a clear-cut, life-or-death situation? Maybe you have a dismasting but are stable, or a crew member has an injury that isn’t critical but requires advice. This is where a satellite messenger like the Garmin inReach Mini 2 shines. Operating on the Iridium satellite network, it provides true global two-way text messaging, allowing you to communicate the specifics of your situation to rescuers or stay in touch with your shore-side contacts.
The inReach Mini 2 is a multi-tool. Beyond its interactive SOS capabilities, you can use it to get detailed marine weather forecasts, share your location with family back home via a web-based map, and navigate with basic GPS functions. This versatility makes it an incredibly valuable piece of equipment for the entire duration of a voyage, not just in an emergency.
The primary considerations are cost and power. The device requires an active satellite subscription plan, which adds an ongoing expense. Its rechargeable battery also needs to be managed carefully on a long passage, unlike the multi-year standby life of a traditional PLB. The inReach is for the sailor who values communication and tracking capabilities and is willing to manage the subscription and power requirements.
McMurdo FastFind 220: A Rugged and Reliable Lifesaver
When you’re facing heavy seas and brutal conditions, you want gear that feels bombproof. The McMurdo FastFind 220 is that kind of device. McMurdo is a legacy brand in marine safety, and their products are known for their rugged construction and unwavering reliability. The FastFind 220 is waterproof to 10 meters and built to withstand the shocks and vibrations of life on an offshore vessel.
This PLB is a straightforward, no-nonsense workhorse. It incorporates a powerful GPS for rapid position acquisition and a bright, flashing SOS light to aid in visual location. The activation is a simple three-stage process designed to be easy to operate in an emergency while robust enough to prevent accidental activation.
The FastFind 220 doesn’t have the latest bells and whistles like RLS or two-way messaging. Its value lies in its proven performance and durability from one of the most trusted names in the business. For the conservative bluewater cruiser who prioritizes robust engineering over cutting-edge features, the FastFind 220 is a rock-solid choice.
SPOT Gen4 for Tracking and Non-Emergency Check-Ins
For many sailors, a huge part of a remote expedition is sharing the journey with friends and family back home. The SPOT Gen4 is built around this idea. While it has a critical SOS button that transmits your coordinates to emergency responders, its main appeal lies in its tracking and messaging features. You can send pre-programmed "I’m OK" messages at set intervals, let your contacts follow your progress on a map, and send custom messages.
This functionality provides tremendous peace of mind for loved ones ashore. It turns a silent, unknown voyage into a shared experience and provides a simple, one-button way to check in without firing up a complex satellite phone.
The key tradeoff is the satellite network. The SPOT Gen4 uses the Globalstar network, which, while extensive, does not offer the 100% global coverage of the Iridium (used by Garmin) or Cospas-Sarsat networks. For expeditions in the polar regions or certain parts of the southern oceans, coverage can be spotty. It’s an excellent choice for coastal cruising and well-traveled ocean routes but may not be the best option for true high-latitude or round-the-world expeditions. Like the Garmin, it also requires a subscription.
Kannad SafeLink SOLO for Dedicated Marine Performance
The Kannad SafeLink SOLO is a PLB designed from the ground up with the "person in the water" scenario as its primary focus. Kannad is another highly respected name in commercial marine safety, and that heritage is evident in the SOLO’s design. It’s built to be carried on the person and is often integrated directly with inflatable life jackets for automatic activation upon inflation.
This is a specialized tool. It features a powerful 406 MHz satellite signal and a 121.5 MHz homing signal to help rescuers pinpoint your location once they are in the vicinity. The unit is rugged, fully waterproof, and has a battery life that allows for a minimum of 24 hours of continuous operation even in cold conditions.
The SafeLink SOLO is not a general-purpose outdoor beacon; it’s a piece of marine life-saving apparatus. It’s for the sailor who wants a device optimized for the specific, and most terrifying, risk of going overboard far from shore. Its focus is singular: get you found and get you rescued from the water.
GME MT610G: Buoyant Design with a 10-Year Battery
For the long-distance cruiser, simplicity and long-term reliability are paramount. The GME MT610G delivers on both fronts with two major advantages: it’s inherently buoyant without a special pouch, and it boasts an impressive 10-year battery life. That extended battery life means less worry and a lower total cost of ownership over the life of the device.
The Australian-made MT610G is a robust, GPS-equipped PLB that does its job without fuss. It features a simple, non-subscription activation, a high-intensity strobe light that is automatically activated by water, and a compact, ergonomic design. It’s a true "set it and forget it" piece of safety equipment.
This beacon is the perfect choice for the sailor embarking on a multi-year circumnavigation or for anyone who values low maintenance and long-term dependability. It might not have the interactive features of a satellite messenger, but its foundational safety features are top-notch, making it a practical and trustworthy companion for any remote voyage.
Choosing a PLB is a deeply personal decision that balances your budget, your style of sailing, and your tolerance for risk. Whether you prioritize the confirmation of an RLS signal, the communication of a satellite messenger, or the simple reliability of a dedicated beacon, the most important step is getting one and clipping it to your PFD. The best gear in the world is useless if it’s stowed below when you need it most. Prepare well, make a smart choice, and then focus on the real goal: the unmatched freedom of the open ocean.
