Comments about POLAR RS300X Heart Rate Monitor Watch:
Yes this is cool kit. Polar was one of if not the original INTHIS cetegory. All my serious mates use Polar to train if they are focussed on work rate and healthy smart training. Whether at Olympic level of Ironman level.
Problem is Polar instruction booklet is a joke. You can only get minimal info. So you have to log on to the help chat line at Polar.com to get the behind the scenes multiple layers of tech and programming on this model to dial in your training zones, etc etc. Very helpful. But a drag. There is a thick booklet in 27 languages. Would be better to put in to ENGLISH with all the scoop to get the whole thing working on my / your time zone. Not just when Polar is operating. It works great BUT a major DRAG TO SET UP. OH and I bought a FitBit first...that's a JOKE. Took it back and SAuth was slick exchanging it. Great service. David J.
