SupplyApp has a distance meter or rangefinder that can correctly determine the distance between two objects. These meters are capable of measuring in both feet and inches, as well as metric measurements. Laser distance meters provide great levels of accuracy and have bright LCD displays that are easy to read. In addition to measuring distance, certain laser distance meters can also measure area and volume. Distance tape measures work by broadcasting and receiving ultrasonic waves to calculate distances. Binocular rangefinders, hunting rangefinders, and monocular rangefinders are all available.
