- Compatibility of the pulse belt with electrical equipment in fitness studios is (always) if not. Clear benefits have here models of Polar and Suunto.
- Time is of the GPS reception. This took me aback already negative. No satellite, no exact time. Well, you can not bear this clock as a fashionable part of every day.
- The manual is so simple that I feel again as a disadvantage if you have specific questions about each feature. Ohnen Internet forums and helpdesks is nothing there. For normal use, however, the manual is ok.
To summarize:
Compared to the 800 series of Polar with the external GPS Pod I my luck with the 310XT found. It has everything I need and more. An accurate GPS is accompanied by a variety of queried data before, during and after exercise motivate ago. If you have an FR 305, then pays the switch to the 310er not necessarily, since the water leaks and longer battery life of 310er face a huge price jump. Would I buy again my 310 XT? Definitely yes.
