Scan & Trace vs Ring Sizer

Scan & Trace is a valuable, time-saving app for pilots and crew. The app enables you to quickly gain access to information about status on suit or to register your suit for service or repairs. Open the app, hover your phone/tablet over the barcode of the suit and you’ll be taken to the VIKING portal.
