The Nova Pro 100 is the latest in what Light & Sound Technology can offer. It is an AVS (AudioVisual Stimulation) device. This NovaPro 100 will influence your state of mind using specially designed light and sound stimulation. Flickering lights and pulsating sound are used to influence your mood. The NovaPro is a very effective relaxation tool, a good assist to meditation, and can aid the learning process. The NovaPro has 100 relaxation, meditation, sleep, learning, energizing, visualization, entertainment and specialty performance sessions, and room for 100 more. Sessions are organized in 8 categories: relax, meditate, sleep, learn, energize, visualize, entertain and special. Sessions are selected by selecting a category then a session within the category (so you don't have to wade through 100 sessions every time). In any category, the selection process proceeds through the built-in sessions, then through any downloaded sessions in that category.
