The S610i is a valuable training tool that makes analysis easy. With Infrared technology, you can download directly to your PC without a separate interface.* Get back from your workout and in seconds, a performance breakdown is right there on your PC. The enhanced Polar Performance software lets you look at your workouts every 5, 15 or 60 seconds. The 610i was designed for the athlete looking for a competitive edge.
*Please note, your PC or Laptop must have an IR window or you will need a separate Polar IR interface.
Strengths: Impressive functions, Computer analysis of session via Infrared, easy to use.
Weaknesses: Quite pricey considering no speed/altitude measurement.
Bottom Line:
First bought this product after being recommended/forced to buy it by a coach i previously had. He turned out to be no good but the HRM was brilliant. It has extensive memory allowing for numerous long rides to be stored and then later analyized with software on your computer. There are different exercise modes available so things like sprint training can be done much more effictively and accurately. However, it does not record altitude or speed like some other models do so you will have to buy a cyclecomputer too if you want such information. All in all an impressive bit of kit that does all you could want from a HRM.(Sprints,Avg and Max HR,Calories burned etc).
