Dot and Line lasers are alignment tools that produce single or multiple dots of reference on a surface area creating a virtual reference point or line for alignment purposes. A number of different variations of these tools are now readily available for various applications. A complementary tool for these devices is the laser detectors. They are light sensors that can be mounted at a distance on a rod to capture the incoming beam. Once the beam hits the target an audible sound is heard indicating the aligned position. These systems can act as convenient tools for aligning outdoor objects precisely on relatively large distances.
