Garmin Replacement HRM Strap,
Verified Purchase(What is this?)
This review is from: Polar Wearlink Plus Soft Strap Only Size M-XXL (Sports)
Like several other reviewers here I have experienced unpredictable readings using my Garmin soft strap that I got with my Garmin Forerunner 910XT GPS Watch with Premium Heart Rate Monitor. My Garmin device would frequently report a hear rate of over 220 bpm and I'm quite sure that if that was my actual heart rate I'd have noticed some symptoms, maybe even experienced what the inside of an ambulance looks like. Like some other reviewers I also noticed that the make of shirt that I was wearing seemed to give different results. After much research I read that this Polar strap is compatible with the Garmin heart rate monitor sender device and that people had reported it to be more reliable and so decided to give it a try.
I've now had this Polar Plus soft strap for just over a month now and have used it maybe 15 times in that period. To date it has never given a reading over 180bpm and so I've come to trust the readings far more than the Garmin strap and can now resume heart rate training.
So just to confirm - this Polar heart rate monitor strap is compatible with the Garmin heart rate monitor sender device used on the Forerunner series of devices, the press-stud distance and size are identical and so no modifications are required. It gives more accurate readings that the Garmin strap and so I have no hesitation in recommending it.
