A three-dimensional (3D) coordinate measurement device and method of operating combines tracker and scanner functionality. The method includes selecting an operating mode on the coordinate measurement device. A first light is emitted from the coordinate measurement device. At least two angles associated with the emitting of the first light are measured. A second light is received with an optical detector, wherein the second light is a reflection of the first light off of the retroreflector or the surface. A distance is determined based at least in part on the selected mode, the emitting of the first light, and the receiving of the second light. Three dimensional coordinates of at least one point in the environment are determined based at least in part on the measuring of the at least two angles and the determination of the distance.
