hasahuba6 years ago000Why is the HRM Dual strap shown here? Is this compatible with the VIRB Ultra 30? That means my pulse is shown b in the video?Show in original language (German)vinci6 years ago000Hello Hasahuba, The VIRB Ultra 30 can receive and record data from ANT+ devices. So not only HRM, but also power meters and cadence/speed sensors of a racing bike. There are many videos about this on YouTube... google it. GreetingsShow in original language (German)Comment
