The ACR OLAS Tag is a Wearable Crew Tracker that integrates OLAS (Overboard Location Alert System) technology. 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 sounds an alarm and records the latitude and longitude of the incident using the phone or tablet’s 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. 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.
