Emax green laser pointer with on/off switch

The switch is the point

Almost every laser pointer uses a momentary button: press it and the beam is on, release it and the beam dies. That is fine for flicking at a slide. It is useless when you need a steady beam for several minutes. This version of the Emax green pointer has a latching switch, so one press turns it on, and it stays on until you press again.

Built around physiotherapy use

Physiotherapists are the main buyers of this model. The technique it supports is simple: the beam is left on and the patient focuses on the point of light, which gives them a fixed visual target to track or move towards during rehabilitation exercises. A momentary button makes that awkward for the practitioner, who ends up concentrating on the pointer rather than the patient. A latching switch removes the problem entirely.

Also useful outside the clinic

Anyone running long presentations benefits from the same feature. Business briefings, teaching sessions, astronomy talks and forensic work all involve holding a beam on one spot while you talk, and a constant-on pointer means your hand can rest on a lectern instead of gripping a button. Green is the practical colour for this, as it is the wavelength the eye responds to most readily and it holds up over the length of a large room.

Power

Two AAA batteries are included. Because the beam can be left on for extended periods, it is worth switching it off between exercises or slides to preserve battery life.
