6 Best Personal Locator Beacons For Dinghy Adventures That Actually Float
For dinghy safety, a floating PLB is essential. This guide reviews the 6 best buoyant models, ensuring your SOS can be sent even if dropped overboard.
You’re heeled over, spray in your face, and the little dinghy is absolutely flying across the bay. Suddenly, a gust hits, the boom swings hard, and the world turns upside down. In the cold, disorienting chaos of a capsize, your most important piece of safety gear is the one you can find and activate—and that’s impossible if it’s already on its way to the seabed.

Why a Floating PLB is Essential for Dinghy Safety
When you end up in the water unexpectedly, your world shrinks to what you can touch. A Personal Locator Beacon (PLB) that sinks is functionally useless the moment you lose your grip. In the critical minutes after an accident, you don’t have time to dive for a lost device; you need it attached to you or floating nearby, ready to be activated. This is why for any small watercraft activity, from dinghy sailing to kayaking, buoyancy is a non-negotiable feature.
A PLB is a direct link to search and rescue. When activated, it sends a powerful 406 MHz signal to the Cospas-Sarsat satellite network, a global system monitored by government agencies. This signal contains your unique code and, for GPS-enabled models, your precise location. It’s a one-way distress call that says, "This is a life-threatening emergency, come get me." Unlike a cell phone with no service or a VHF radio with limited range, a PLB works almost anywhere on the planet.
For dinghy sailors, the environment is dynamic and unforgiving. A capsize, a man-overboard situation, or getting swept out by a current can happen in seconds. Having a PLB that floats means it remains a viable rescue tool even if it’s dropped or becomes detached from your PFD. It transforms a potential tragedy into a solvable problem, giving you and the rescue services the best possible chance for a positive outcome.
ACR ResQLink View: Buoyant with a Digital Display
Get rescued faster with the ACR ResQLink View PLB. This buoyant, lightweight beacon sends your GPS location to search and rescue via satellite and features both LED and infrared strobe lights for increased visibility.
Imagine you’re in the water, cold and uncertain. You’ve just activated your PLB, but now the waiting begins. Is it working? Did the signal go through? The ACR ResQLink View answers these questions with a clear, simple digital display, providing crucial peace of mind when you need it most.
This device is inherently buoyant, meaning it floats without any special pouch or case. That’s a massive advantage when your hands are cold and your mind is racing. The standout feature is its screen, which provides live status updates. It confirms the beacon is active, displays your exact GPS coordinates, and provides on-screen instructions to guide you through the activation process. This feedback loop is incredibly reassuring, letting you know that help has been summoned.
The trade-off for that screen is a slightly higher cost and a bit more bulk compared to its minimalist cousins. However, for sailors who value confirmation and clarity in a high-stress scenario, the ResQLink View is a top contender. It’s a robust, reliable unit that removes the guesswork from a distress call.
Ocean Signal rescueME PLB1: Compact with Float Pouch
If space on your PFD is at a premium and every gram counts, the Ocean Signal rescueME PLB1 is likely already on your radar. It is famously small and lightweight, making it one of the most compact PLBs on the market. For dinghy racers or minimalist sailors, its unobtrusive size is a major selling point.
However, there’s a critical detail: the PLB1 is not inherently buoyant. To ensure it floats, you must use the included neoprene floatation pouch. This makes proper setup essential before you even leave the shore. The pouch adds a little bulk, but it’s the only thing keeping this tiny device from sinking if dropped.
This design presents a clear trade-off. You get an incredibly compact and light rescue device, but you accept the responsibility of always using it with its float pouch. For the disciplined sailor who has their gear dialed in, this is a perfectly acceptable compromise. For those who prefer a more foolproof, grab-and-go solution, an inherently buoyant model might be a better fit.
Garmin inReach Mini 2 with Float Case for 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.
Sometimes an issue on the water isn’t a life-or-death emergency, but you still need to communicate. Maybe a rudder pin sheared off and you’re drifting, but in no immediate danger. This is where a satellite messenger like the Garmin inReach Mini 2 shines, offering a different kind of safety net.
Unlike a traditional PLB, the inReach Mini 2 provides two-way text messaging via the Iridium satellite network. This allows you to communicate with family, friends, or rescue services about the nature of your problem. You can also get weather updates, track your route, and share it with others. The SOS button connects you to the Garmin IERCC, a private 24/7 emergency response coordination center that will liaise with local SAR teams.
To make it viable for dinghy sailing, you’ll need to pair it with an accessory float case. It’s also important to remember that all its communication features, including SOS, require an active monthly or annual subscription. The inReach Mini 2 is less of a pure emergency beacon and more of a comprehensive communication tool for the sailor who wants to stay connected, solve problems remotely, and have a robust SOS function as a backup.
McMurdo FastFind 220: Rugged and Ready to Float
The McMurdo FastFind 220 is a workhorse. It’s built with a focus on durability and simplicity, designed for sailors who want a dedicated rescue device that will perform without fuss when conditions turn sour. It’s fully waterproof and, crucially, it’s inherently buoyant, so it will float if you drop it overboard.
This PLB is all business. Activation is straightforward via a protected button, and it transmits on both the 406 MHz satellite frequency and the 121.5 MHz homing frequency used by rescue aircraft. It utilizes both GPS and the Galileo satellite networks, which means it can get a faster and more accurate position fix. A bright, flashing LED light also acts as a visual signal to help rescuers pinpoint your location in low light or at night.
The FastFind 220 doesn’t offer a digital display or two-way messaging. Its mission is singular: to get your distress signal and location to rescuers as reliably as possible. This makes it an excellent choice for the sailor who wants a bombproof, no-subscription-required safety device that they can trust completely in an emergency.
SPOT Gen4: Tracking Your Trip with a Float Case
The SPOT Gen4 occupies a space similar to the Garmin inReach, acting as a satellite messenger with a focus on tracking and one-way communication. It’s a great tool for letting family and friends follow your adventure in near real-time and for sending pre-programmed "I’m OK" messages from offshore.
Functionally, the Gen4 allows you to send custom messages, request non-emergency help from your personal contacts, and share your GPS track. The SOS button connects to a private emergency response center, which then coordinates with local authorities. Like other satellite messengers, it requires a subscription plan to function and needs a separate float case to be suitable for dinghy sailing.
It’s important to note that the SPOT devices operate on the Globalstar satellite network, which has known coverage limitations compared to the Iridium network (used by Garmin) or the Cospas-Sarsat system (used by PLBs). For coastal dinghy adventures in North America or Europe, this is rarely an issue. However, for sailors venturing into more remote waters, particularly in the southern hemisphere, understanding the network’s coverage map is essential before relying on it.
ACR ResQLink 400: Simple, Buoyant, and Reliable
Think of the ACR ResQLink 400 as the classic, distilled version of a modern PLB. It does one job, and it does it exceptionally well. For the dinghy sailor who subscribes to the "less is more" philosophy, this beacon is a perfect fit, offering proven technology in a simple, robust package.
Like its sibling, the ResQLink View, the 400 is inherently buoyant. There is no pouch to forget and no case to add. It features multiple levels of protection against accidental activation, including a break-off antenna cover and a sturdy activation button. It leverages both GPS and Galileo satellite systems for a quick, accurate fix and includes both a white LED strobe and an infrared strobe for nighttime rescue operations.
The primary trade-off here is the lack of a digital display. You won’t get on-screen confirmation that your signal has been received, relying instead on the blinking indicator light. For many, this is a worthy compromise for a simpler, more affordable, and arguably more rugged device with fewer potential points of failure. It is the definition of a pure, dedicated life-saving tool.
PLB vs. Satellite Messenger: What Dinghy Sailors Need
The most common point of confusion is the difference between a PLB (like the ACR or Ocean Signal models) and a satellite messenger (like Garmin or SPOT). A PLB is a one-way distress beacon. When you press the button, it sends a powerful, encoded SOS signal directly into the government-run Cospas-Sarsat rescue system. There are no subscription fees, and its sole purpose is to save your life in a grave and imminent danger.
A satellite messenger, on the other hand, is a communication device that also has an SOS feature. It allows for two-way texting, weather forecasts, and location tracking, all of which require a paid subscription. Its SOS signal typically goes to a private response center that then coordinates with official search and rescue. This two-way communication can be invaluable for resolving non-critical issues or providing rescuers with more context about your situation.
So, which do you need?
- For baseline, foolproof safety: A buoyant PLB is the gold standard. It’s a dedicated, subscription-free device with a more powerful signal that plugs directly into the global SAR network.
- For communication and convenience: A satellite messenger is fantastic for staying in touch, getting weather reports, and managing minor incidents before they become major emergencies.
For many offshore sailors, the answer is to carry both. But for most dinghy adventures, a reliable, floating PLB should be considered the essential foundation of your safety kit. It is the simplest and most effective tool for turning a worst-case scenario into a rescue story.
Ultimately, the best piece of gear is the one you have with you and know how to use when things go wrong. Choosing a floating PLB or messenger is an investment in peace of mind, freeing you up to focus on the wind, the water, and the simple joy of sailing. Make a smart choice for your needs, clip it to your PFD, and get out on the water.
