I bought HRM-dual device but it is not listed in connect-app?? How Can I use the device?
You must connect it to a Garmin device. Watch or bike computer.
Download the MapMyFitness App. and connect with these instruction: https://support.mapmyfitness.com/hc/en-us/articles/200117774-How-do-I-connect-a-Bluetooth-sensor-#:~:text=After%20recording%20a%20workout%20with,workout%20summary%20for%20that%20activity.&text=Go%20to%20your%20device's%20General,to%20pair%20from%20this%20screen. Then you can tie it to Garmin Connect if you wish or just use the MapMyFitness App. found that trick here: sforums.garmin.com/.../hrm---dual-band-issue-with-the-app
