Freestyle 594 is a highly accurate and versatile exercise instrument for walkers and runners. It can measure steps, distance, calories burned, and can function as a stopwatch. Before using the device, you need to program it with your weight and stride length for precise results. Attach the pedometer to your belt or waistband and make sure it's parallel to the ground for proper readings. The device will count your steps and display the number in the step mode. You can also track the distance traveled in miles or kilometers in the distance mode.
