A laser beam generating device, comprising: a housing; and a laser light generator disposed in the housing and comprising a three beam generator operable to generate three output beams (70a, 70b, 64c), the three beam generator of the laser light generator including a first light source projecting light along an optical axis toward a first beamsplitter, and a first collimating lens interposed on the optical axis between the first light source and the first beamsplitter, wherein the first beamsplitter has two incident surfaces (66a, 68a) orientated at forty-five degrees in relation to the optical axis, such that a first portion of the light from the first light source is incident on a first surface of the two incident surfaces and reflected by the first surface as a first output beam in a first direction orthogonal to the optical axis and a second portion of the light from the first light source is incident on a second surface of the two incident surfaces and reflected by the second surface as a second output beam in a second direction opposite the first direction, wherein the first light source is arranged in relation to the first beamsplitter such that a third portion of the light from the first light source bypasses the first beamsplitter and forms a third output beam projected parallel to the optical axis; the housing has multiple openings, such that the housing has an opening for emitting each generated light beam (70a, 70b, 64c, 70c, 70d); the laser beam generating device being characterised in that: the laser light generator further includes a two beam generator which includes a second light source, a second collimating lens and a second beamsplitter, arranged and aligned with respect to each other such that the collimated light beam of the two beam generator is split into two light beams (70c, 70d), the laser light generator further including an automatic power control circuit and a power source comprising one or more batteries electrically coupled to the automatic power control circuit; and the laser beam generating device further comprises a switch disposed on the housing and electrically coupled to the power source, the switch including a three-beam setting, a two-beam setting and a five-beam setting, to cause the automatic power control circuit to supply power to one or both of the generators (20, 22), and the laser light generator is thereby arranged to generate up to five light beams (70a, 70b, 64c, 70c, 70d), the light beams oriented and aligned along five directions so as to appear to be originating from a common point. a housing;
