The Sportline Walking Gear Step & Distance 340 Strider Pedometer is perfect for your personal goals. Not only does the 340 keep accurate track of your steps and distance with the patented APD (Advanced Pendulum Design), but it also allows you to adjust the measurements to fit your personal stride. The pedometer can measure and calculate in two modes: Step Mode and Distance Mode. Step Mode shows you how many steps you have taken, and the Distance Mode shows the distance you have walked in either miles or kilometers. Input your stride length with a range from 12 inches to 60 inches.
