A specialized pocket-sized visual aid designed for tabletop miniature wargaming. 
Instead of projecting a single point, it emits a flat, vertical line of red laser light onto the gaming table. 
This allows players to instantly verify true line-of-sight (LOS), determine complex firing arcs, and settle rules disputes without bumping miniatures or physical terrain.
3 x LR44 button cell batteries (included in the packaging).
