Query: a great pedometer

I was so frustrated trying to program my first two pedometers that I went on line for reviews. Taht led me to select Omron. Very easy to program and easy to see. Accurancy is dependant on how you calculate step base and that will vary with conditions, I do a lot of mountain hiking. It provides a good estimate. It does work in a pocket or waistband.
