   en.wikipedia.org/wiki/Laser_level

   In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed red or green beam in a plane about the horizontal and/or vertical axis.

   en.wikipedia.org/wiki/Laser_rangefinder

   A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.

   Laser level – control tool consisting of a laser beam projector that can be affixed to a tripod, and which projects a fixed red or green beam along the horizontal and/or vertical axis. A rotary laser level is a more advanced laser level in that it spins the beam of light fast enough to give the effect of a complete 360 degree horizontal or ...

7. Tribrach (instrument) - Wikipedia

   Re-center the cross-hairs using the thumb screws, then fine-tune the level using the tripod legs. Once the tribrach is nearly centered over the marker, level the tribrach the last little bit using the thumbscrews. Slacken the tribrach from the tripod head and slide it the last 4-5mm so that it is centered over the marker and is level.
