A system is provided for determining a distance to a target. In an exemplary embodiment, the system includes a pole and a distance measuring device. The pole includes a plurality of sockets formed in a surface of the pole above a selected lower reflecting point and a reflector mounted in each of the plurality of sockets. The lower reflecting point defines a minimum distance from a first end of the pole above which the reflectors are located for use with the distance measuring device. At least a portion of a signal received from the distance measuring device is reflected back to the distance measuring device by a receiving reflector. The distance measuring device includes a transmitter that transmits the signal at a first time, a receptor that receives the reflected signal from the receiving reflector at a second time, and a processor to determine the distance from the transmitter to the receiving reflector using the first time and the second time.
