Claim Text:
1. Layout equipment for locating a plurality of positions at a construction site, comprising: a laser target rod having an elongated rod body including retroreflective material on the elongated rod body, the retroreflective material extending substantially an entire length of the elongated rod body, and scale markings visible on the laser target rod, a self-leveling laser transmitter for projecting a first beam of laser light and a second beam of laser light parallel to the first beam of laser light, and for receiving laser light reflected from the laser target rod, the laser transmitter including a first wireless communication unit, and a transmitter control, wherein the transmitter control is responsive to the first wireless communication unit, wherein the beam of laser light is a beam of green laser light, and wherein the second beam of laser light is reflected from the laser target rod and detected by the laser transmitter such that a distance between the laser transmitter and the laser target rod is determinable through time-of-flight calculation, and a remote control device, including a second wireless communication unit, for wirelessly communicating with the laser transmitter to cause the laser transmitter to project the beam of laser light toward a selected one of the plurality of positions at the construction site, and for signaling a user of the layout equipment when the laser target rod has been placed at the selected one of the plurality of positions.
