Presenting the newly updated 4x3razor Digital Pedometer by Ozeri - the world's thinnest and most advanced 3D activity tracker. Unlike traditional pedometers that do not work accurately unless secured vertically, the 4x3razor utilizes a new advanced 3D Bosch sensor from Germany with Tri-Axis technology that provides superior accuracy in any orientation, whether up, down, flat, on its side, or at any angle. The 4x3razor's Bosch Sensor is a digital accelerometer which is far more accurate than mechanical sensors found in other devices. Compact, sleek and razor thin, the 4x3razor Digital Pedometer is only 0.5 cm (less than 0.2") thick and weighs just half an ounce to fit into the tightest pocket. It includes a detachable lanyard and belt clip for the ultimate convenience. A personal trainer par excellence, the 4x3razor is used by professional 100 mile ultra-runners to accurately record steps, distance, calories consumed, fat burned and exercise time. This advanced digital pedometer counts up to 1 million steps with 30-Day Memory, and includes a built-in Clock and Sports Timer with Auto Sleep technology. The 4x3razor now features MotionLock to prevent unintended motion detection, such as when traveling. It also filters out vibrations and only begins counting after it detects a sequence of continuous steps for greater accuracy. The 4x3razor Digital Pedometer ships with an installed and extra Lithium battery, a belt clip and detachable lanyard and instruction manual. Your satisfaction is 100% guaranteed.
