cadence speed heart monitors
I have got a ant+ cadence speed monitor also a zephyr hxm blue tooth heart rate sensor. I am trying to canvass opinions as which is the best monitor to display mainly cadence and speed. I have a phone app which will do the job fine but probably won't last on 4hr+ rides. I don't want the latest garmin, but consider older models plus any other manufacturers.
Comment please as to what they are like?
