Safety Leash for Pedometer (1) Unit. Helps Save Pedometers From Loss Product Features - Attached to Pedometer Clip - Prevents Loss Product Description Although your pedometer has a belt clip, add a pedometer leash for extra insurance that your pedometer does not hit the ground if it somehow falls off your waistband. The leash attaches to your pedometer at one end, and a metal clip to your waistband ensuring that you never lose your pedometer. Bought as a replacement for the pocket leash and alligator clamp that came with an Omron Walking Style Pedometer. When the pedometer is carried loose in a pocket it NEEDS the lanyard and clamp, or I found it will lose up to half the steps I take. Clamping it -- even on a leash -- keeps the pedometer in synch with your hip motion, and thus able to record every step. This leash came with two alligator clamps -- one plastic and one metal. I choose the plastic clamp, as it seemed closest in appearance to the Omron original. I have found that the replacement plastic clamp does NOT have the clamping bite -- the hold -- the original had. It works most of the time, but comes loose too much. (I can not speak for the metal clamp, since I discarded it when I installed the replacement lanyard.) Still, this replacement lanyard and clamp makes the pedometer count steps correctly and the price was right. Shipping was quick too!
