Like other DIGI-WALKER™ pedometers, the SW-700 model measures your steps and calculates distance by multiplying the number of steps you take by your stride length. (This model accepts stride lengths in centimeters.) What makes the SW-700 special is that it can be programmed with your weight (in Kilograms) to help you determine your estimated caloric expenditure. While not as accurate as the NL-2000 activity monitor in determining the calories you burn each day, the SW-700 provides a good approximation of how your activity level translates into calories burned. This model is about 2" x 1 1/2" x 3/4" and weighs less than 3/4 ounce. First Class Mail shipping and handling for 1-3 units is only $5.95. Learn more about shipping and handling fees. Buying a gift?
