The ACR OLAS CORE is a small, portable, wireless Man Overboard (MOB) Alarm system that triggers an instant emergency alert, within 4 seconds of a MOB incident. The CORE provides coverage for vessels up to 50 ft and the OLAS EXTENDER is an available option to expand coverage for vessels up to 80 ft. With the ability to connect to a total of 15 wearable OLAS Tag and/or OLAS Float-On transmitters, the CORE creates a virtual lifeline to your crew members and acts as your boat’s base station to monitor and alert the crew should one of the transmitters go missing. The CORE can also connect with the ACR OLAS mobile app which, in the case of a MOB incident, provides easy to read directional screens with a bearing and trackback to the point where the alarm was triggered. The app also provides essential MOB position and procedure prompt screens, supporting the crew during the stress of a recovery operation.
