This green laser pointer can be seen in mid-air in medium lit to dark conditions, not just the laser dot but also the beam itself. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell.
Made of solid heavy duty construction, this laser is very durable and unscrews in four places, giving you access to the laser diode. Very bright green laser at 532 nm wavelength. Momentary push button switch. Uses 2 x AA batteries (included).
