The ACR OLAS Tag is a compact, ‘Smart’, man overboard system transmitter. It can easily attach to adults, children, pets and objects such as overboard floatation devices or Personal Locator Beacons. 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. The ACR OLAS mobile application technology detects a break in its ‘virtual tether’ to the tag within 8 seconds of a Tag going missing. The mobile phone(s) then sound an alarm and records the latitude and longitude of the incident using the phone or tablets GPS. ACR OLAS then aids the crew with the MOB recovery, clearly directing them to the GPS location where the MOB occurred with clear visual signals and bearing data. ACR OLAS stores all location data and time of incident required by the rescue services.
