With the Vaughan 100 ft. Laser Distance Measurer, you'll get fast, clear and precise distance measurements up to 100 ft. away. This precision distance measuring tool is lightweight, compact and much faster and easier to use than a tape measure. Here's how fast and easy it is to take extremely accurate distance measurements in less than 5-seconds: Press the power button, aim the laser dot, press the power button again, read the measurement. It's that simple, yet this precision instrument offers accuracy of plus or minus 2 mm. Try that with a flimsy tape measure. A bright LED digital readout makes it much easier to read than a tape measure too, a plus for using outdoors and in low light conditions. For added versatility, you can take static measurements as well as walking measurements. And you can select readouts in feet, inches or meters. At just over 4 in. L, it's small enough to fit in hand and pocket. Taking multiple measurements. Use the included wrist lanyard to keep it close at hand.
