The OLAS tag is a compact OLAS transmitter, easily attached to adults, children, pets and objects such as overboard floatation devices. The tags are tracked by the OLAS application on a mobile device or via the Core, Guardian and Extender.


Seconds after the tag breaks connection with an OLAS receiver the crew are alerted by the OLAS alarm and light, whilst the OLAS MOB rescue screen are activated on the OLAS mobile application.


Each tag is supplied with a universal silicone wrist strap with stainless steel buckle and a pre-installed CR2477 Battery (user replaceable).


  • Track with the OLAS Guardian and Core (Vessels up to 50ft)

    Connect up to 15 OLAS transmitters (OLAS tag or OLAS Float-On) to any OLAS receiver. Within 2 seconds of the connection breaking the MOB alert will activate alerting crew to the incident.

    Track with the OLAS mobile application

    Within 8 seconds of a 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.
