The ACR ResQLink PLB450 (Model 2933) is a compact marine personal locator beacon built for mariners, offshore anglers, and anyone who works or plays on open water. It pairs a 406 MHz Cospas-Sarsat satellite signal with an Automatic Identification System transmission, so a distress call reaches both the global rescue network and nearby vessels within roughly five miles. ACR Electronics designed this beacon to install inside a life jacket for semi-automatic activation when the jacket inflates, which matters most in a man-overboard situation where seconds count. For boaters comparing options across our personal locator beacons, the PLB450 covers both satellite and local notification in one orange housing.
Positioning comes from a multi-constellation GNSS receiver reading GPS, Galileo, and GLONASS, with location accuracy within 100 meters through the Cospas-Sarsat network. A 121.5 MHz homing signal guides rescue craft to the final approach, while Return Link Service uses the Galileo network to confirm your distress message was received, indicated by a blue LED on the unit. The local vessel notification system gives nearby boats a position before official assets arrive. A white visible strobe and an infrared strobe aid nighttime recovery, and Near Field Communication lets you test and manage the beacon through the ACR smartphone app. Power comes from a lithium-ion battery rated for a 5-year life and over 24 hours of operation at 20°C, per manufacturer specifications.
A buyer reaches for the PLB450 when the consequences of going overboard offshore are real and immediate. Stowed in a life jacket or clipped to a PFD, it activates without fumbling for a switch, then transmits to satellites overhead and to any vessel monitoring traffic nearby. It carries Cospas-Sarsat approval and meets recognized international radio standards for marine emergency use. Pair it with other gear from our safety systems lineup, or look at our vessel identification systems for full bridge coverage. The included accessory clips support both oral inflation tube and webbing mounting.
No. The PLB450 transmits on the 406 MHz Cospas-Sarsat satellite network with no subscription or monthly fee. Owners do need to register the beacon with their national authority so rescue coordinators can match the signal to the registered user and contact details during an emergency.
The 406 MHz satellite signal reaches the global Cospas-Sarsat rescue network and triggers an official response. The Automatic Identification System transmission separately alerts nearby vessels within roughly five miles, giving boats in the immediate area a position before official assets arrive. Both run at the same time in a man-overboard situation.
The beacon provides over 24 hours of operational life at 20°C on its lithium-ion battery, per manufacturer specifications. The battery carries a 5-year life and is warranted until its expiry date when tested according to the user manual.
Yes. The PLB450 is designed to install within a life jacket for semi-automatic activation when the jacket inflates. The included accessory clips support oral inflation tube and webbing mounting, so the beacon stays ready without requiring you to locate and operate a switch by hand.
Return Link Service uses the Galileo satellite network to confirm your distress message was received by the rescue system. The PLB450 indicates this confirmation with a blue LED on the unit, giving you direct feedback that help is on the way during a distress event.
