Counts exactly

For the past 2 weeks I known this pedometer in practice. After I had it set up, which was not magic, I tested it on a previously measured distance of 820m. The result: the Omron pedometer is only slightly deviated with 816 meters measured.
The device counts even in your pocket or anywhere else attached to the body, each step does the man or woman, however, can not be reset to zero.
The settings such as step length and body weight can be updated anytime.
A very good and reliable companion on all hikes.
