Abstract

A laser indicator includes a weight mechanism having a bracket with a weight secured to the bracket in a manner where the weight is suspended by gravity. A plurality of laser generators are arranged about the weight, including a horizontal beam generator, a center laser generator arranged at the axial center of the bottom of the weight for emitting a laser point coaxial to the axial line of the weight, and a plurality of vertical beam generators positioned in spaced-apart manner around the axial center of the weight at the top of the weight. The laser indicator can include a stand that includes a seat having a plurality of legs, and a rotary table having a plurality of legs, with the weight mechanism coupled to the rotary table, and the rotary table removably coupled to the seat so that altitude of the weight mechanism can be adjusted. In addition, the laser indicator can include a securing mechanism for coupling the weight to the upper bracket of the bracket.
