What is the difference between a smoke machine and a hazer?
Smoke machines create thick white smoke, whereas hazers create a thinner haze which can be seen when beams of light strike it. Hazers are often used when the blast of smoke from a smoke machine would be too intrusive or noisy. The visibility of smoke created by smoke machines means they’re used for special effects, fire training, and all of the other applications mentioned on this site. Hazers can be left to operate continuously and inconspicuously.
