Wearable Crew Tracker with LED Flashlight and Water Activated Strobe

The ACR OLAS Float-On is a buoyant Wearable Crew Tracker that integrates OLAS (Overboard Location Alert System) technology with an LED flashlight and water-activated strobe. This ACR OLAS technology detects a break in its ‘virtual tether’ to the ACR OLAS Float-On within 8 seconds. The mobile phone(s) then sounds an alarm and records the latitude and longitude of the incident via the device’s GPS.  ACR OLAS then aids the crew with the MOB recovery by clearly directing them to the exact GPS location where the MOB occurred with clear visual signals and bearing data. Finally, ACR OLAS stores all location data and time of incident required by the rescue services.

See and Be Seen

Featuring a robust yet compact and convenient design, the ACR OLAS Float-On includes a button that is easily located in the dark. As an extra safety feature, the strobe light automatically activates once the transmitter’s integrated water sensors detect 6 seconds of water connection. The high-power strobe flashes once every second for up to 20 hours, is visible up to 3 nautical miles away and provides an important additional safety tool for low light rescues. The LED light is effective as a flashlight used to see objects in the distance whilst also emitting side light to ensure complete all-round visibility when acting as a position indicating light or strobe. The ACR OLAS Float-On can be easily stowed on any existing safety gear or in a lifejacket pocket.

Connect and Protect

Users can track up to 6 different OLAS Transmitters with 1 phone/tablet and each individual OLAS Transmitter can be tracked by an unlimited number of phones/tablets.  If you want to track more OLAS Transmitters, add the ACR CORE base station or Guardian Engine Kill Switch and MOB alarm scaling your system to monitor up to 15 OLAS Transmitters.


The ACR OLAS Float-On is a compact, ‘Smart’, man overboard system.  The OLAS Float-On can easily attach to adults, children, pets, and objects such as overboard floatation devices. It is small and portable and can easily be taken from boat to boat to ensure you are always protected.  Activate Solo mode on the app (2G phone signal required) when boating alone and the OLAS app will automatically text message (SMS) your emergency contact with your GPS coordinates in the event you get separated from your boat.

Larger Vessels

The range of the ACR OLAS transmitters allows for coverage on vessels up to 40 ft in length. However, the transmitter is part of a larger scalable ecosystem of ACR OLAS products (transmitters and receivers) that offer additional safety features and can be combined to track large crews on larger vessels.  You can even ditch your phone and utilize your ACR OLAS Float-On with the OLAS Guardian Engine Kill Switch or OLAS Core Base Station as part of a more permanent solution.



ACR OLAS is a must-have addition to your safety toolkit. It provides a simple yet cost-effective safety solution for everyone on board including adults, children, and even pets. Similarly, virtually tether almost anything of value to a system that is guaranteed assist retrieval.
