The OLAS tag is a compact, ‘Smart’, man overboard system. It can be easily attached to adults, children, pets and objects such as overboard floatation devices. The tags connect to the OLAS application on a mobile device.

Within 8 seconds of the man overboard incident occurring, the OLAS mobile application technology detects a break in its ‘virtual tether’ to the tag. The mobile phone(s) then sound a loud alarm, alerting crew to the fact someone is overboard. 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. OLAS stores all location data and time of incident required by the rescue services.

In an MOB situation OLAS will sound an alarm and record the latitude and longitude of the incident using the phone or tablets GPS.
