after playing a bit and finishing a job I had to work 12 hours a day I decided to get a garmin watch. this thing I great. I can connect my cadence sensor too it and broadcast my heart rate to my garmin gps. since it does heart rate in real time it works far better for it then my Apple Watch. Plus my commuter bike gps does not have grade s oI can use the watch to show me that and it is faster at sensing then my other Garmin gps. it is a lot more accurate on steps then the Fitbit is too and it keeps track of your sleep. here is a record of a short ride with the wife and I on the tandem a easy ride as she as been sick. but the top one is the garmin gps with the garmin chest strap and the one below is the garmin watch issuing the cadence sensor on the bike.
