ACR EPIRB1 Pro: The World's Smallest Emergency Beacon for Unmatched Safety at Sea
When it comes to your safety at sea, there's no room for compromise. The ACR EPIRB1 Pro Emergency Beacon is a compact, yet powerful device that operates on the 406MHz satellite band, the international distress frequencies. Monitored by Cospas-Sarsat, the international search and rescue satellite operators, you can rest assured that help is on the way, no matter where you are in the world.
As the world's smallest EPIRB, the ACR EPIRB1 Pro is designed to fit easily on any commercial, fishing, or pleasure vessel. But don't let its size fool you. This emergency beacon is built to last with a 10-year battery life and an extended operational lifespan once activated. It's designed to keep you safe and rescue services informed of your location for as long as possible.
The ACR EPIRB1 Pro isn't just about sending distress signals. It's also about making sure you're found. With a 121.5MHz homing beacon and a high-intensity LED strobe light, rescue personnel can pinpoint your exact location, even in the darkest of nights.
In a situation where every second counts, the EPIRB1 Pro features a Category I Automatic Release Housing (ARH), also known as 'float free'. If you're unable to reach the EPIRB, it will automatically launch from its bracket, trigger, and float to the surface, broadcasting your distress message to the satellite network.
The ARH also includes a versatile adapter, allowing for a variety of refit options. It can be easily mounted using the same holes as larger EPIRBs, such as the Ocean Signal E100/E100G, Jotron Tron 60s, and McMurdo E5/G5.
