The ACR OLAS Float-On Light with MOB Technology (Model 2982) is a buoyant wearable crew tracker that merges the Overboard Location Alert System (OLAS) with a practical LED flashlight and a water-activated strobe. Compact, rugged, and easily attachable to people or gear, it delivers proactive MOB safety and reliable visibility on the water.
Smart MOB Safety in One Wearable
-
OLAS MOB technology and GPS rescue workflow – The Float-On continuously monitors the link to its transmitter. If the virtual tether breaks, the MOB app on your phone or tablet sounds an alarm, records latitude and longitude via GPS, and guides rescuers with precise bearing data to the MOB location. All incident data is stored for rescue services.
-
Water-activated strobe for high visibility – A built-in, water-sensing circuit activates the strobe after six seconds of water contact. The high-power strobe flashes once per second for up to 20 hours and is visible up to 3 nautical miles away, providing a critical signaling tool in low-light rescues.
-
Bright LED flashlight and all-around illumination – Equipped with Low/Med/High LED modes plus side lighting, the Float-On serves as a dependable flashlight and position indicator, helping you see and be seen in any condition.
-
IP67 waterproof and buoyant design – Built to float, resist water intrusion, and attach to adults, children, pets, or objects. Its compact form fits safely on safety gear or inside a lifejacket pocket.
-
Powered, connected, and quick to charge – USB rechargeable with a battery life indicator and fast charge in about 3 hours. Bluetooth 4.1 ensures a reliable wireless link to the MOB app for control and monitoring.
-
Solo mode for independent operations – Activate Solo mode in the app (2G signal required) to automatically text GPS coordinates to your emergency contact if you’re separated from your vessel.
-
Scalable MOB ecosystem – Track up to 6 OLAS Transmitters with one phone/tablet, and an unlimited number of devices can monitor a given transmitter. For larger setups, add the ACR CORE base station or Guardian Engine Kill Switch to scale up to 15 transmitters and beyond.
-
Vessel coverage and ecosystem integration – The system is designed to cover vessels up to 40 ft in length and forms part of a broader OLAS family, delivering enhanced safety features and coordinated MOB alarms across multiple devices.
Whether you’re a solo boater or part of a crew, the ACR OLAS Float-On Light with MOB Technology delivers proactive MOB recovery support with precise location data, audible alerts, and robust signaling. It’s the essential wearable safety tool for modern boating.
