    Manual pretty self explanatory and layout of function very intuitive. Slowly building up to more complex features but this is my first monitor. Experienced users could quickly utilize myriad of functions.

    A criticism I've seen in some reviews (not here) is that this unit is hard to set if you don't read the manual... or, rather, that someone couldn't figure out the initial settings, but had refused to read the manual. The manual is straightforward, and starting from the beginning will get you where you want to go.

    All in all, a great monitor, and at this price a better buy than some of the Polars I passed up to get it.

    Item can be as much of a training aid as you wish. Multiple levels and options as you progress. Measurement of the most simple routines will give you real data-meaning you not someone else 10 yrs. younger and 20 lbs lighter- to set realistic goals and identify a new plateau. The journey starts with the 1st step.
