I just want to say that after all new garmin straps failing, HRM-DUAL, HRM-RUN, HRM-this and that (*) - this is the trusty one hanging in my closet that I come back to:
THE BEST GARMIN Strap ever - the venerable 010-10997-00!
(Can be found on ebay and other places)
It is built like a tank! Battery change after battery change... Soaked in sweat for ten years, keeps hauling and pushing!!
Measures the rate evenly, where the new ones flatline and spike. The most durable sensor.
Garmin! Build an HRM-PRO like the old ones! So we get running metrics with quality LIKE A TANK!
YEAH! CAPS!
Take care everyone, run handsomely!
