With a smoke machine, you can ensure that light beams from lasers, moving heads, and par spots are clearly visible. Smoke machines come in various shapes and sizes. Go for a compact smoke machine if you bring your own lighting equipment to your drive-in show. With a hazer, you can provide a venue with a subtle layer of smoke. A hazer is meant to make light effects pop out more. Go for a fazer if you want to create an exaggerated fog effect.
