Forerunner compatibility

Is the heart rate strap for the Forerunner 50 compatible with the 405CX?


  • My Forerunner 50 monitor worked with the 405.  And My partners Forerunner 50 monitor worked with his 310XT.  Hope this helps image

  • Doesn't the 405 CX HRM have some sort of ability to do calorie calculations on it's own (with the watch) for use at a gym. Or something like that.

    Having said that, any Ant+ device (Garmin) should be ok though I would have thought.
  • Thanks for the replies. That was very helpful.
