So a more flexible band would go a long way to solving the problem? Sounds too good to be true to me. Why would Garmin then not provide that as an option at least?
I have tried wearing the watch super tight, not so tight, right arm, left arm etc but no success.
But I will definitely try the Scosche.
But as I am now returning my Fenix what watch should I get that has similar features but does not make me pay the money and battery drainage of the (for me) useless optical HR?
Yes, that is exactly what I'm saying - a more flexible, more snugly fitting band makes all the difference. Note that the Scosche CPU portion is smaller than the Garmin watches as well so it'll also fit more snugly than the Garmin does.
Instead of ditching your Fenix, you could do what nearly everyone else who is serious about HR does, and use either a chest strap or a good wrist/forearm band like the Scosche to send HR data to the Fenix.
It's easy enough to order a Scosche Rhythm+ on Amazon and try it out and just return if you don't like it. Again, location of placement is key with the Scosche and all bands - note that the Scosche does NOT work well on the wrist if worn like a watch, it only works if you put it in the forearm or for some, the biceps area. I'd bet the Garmin would do even better if it could be placed there with the same form factor, as it's got a more up to date optical sensor. But the Rhythm+ sensor is so good when placed correctly that a better sensor wouldn't even help it in my case.
