About Comptronics' AV Entrainment Products





Comptronic Devices Limited has been designing, developing, researching and manufacturing audio-visual entrainment (AVE) devices since 1984. These AVE devices send flashes of lights using a pair of eyesets and pulses of tones through a pair of headphones to gently guide the brain into altered states of consciousness.

Brainwaves change frequencies based on neural activity within the brain. Each of our senses (vision, touch, smell, taste and hearing) respond to activity from the environment and transmits that information to the brain. The senses of sight and hearing, by their very nature, provide a favorable mechanism to influence brainwaves. By presenting this pulsed audio and visual stimulation to the brain, after a short period of time, the brain begins to resonate or entrain at the same frequency as the stimulus. Because of this, we can slow down the brainwaves for: meditation; providing pain relief; inducing dream states and; improving sleep. The DAVID can also be used to speed brainwaves up, making the DAVID an ideal tool to treat slow brainwave disorders such as Attention Deficit Disorder, closed-head brain injury, fibromyalgia, PMS, chronic fatigue and insomnia and for non-clinical applications such as for enhancing mental performance and boosting creativity.

In addition to entrainment, the imagery created by the visual and auditory stimulation provides a focus for the mind and quietens internal dialogue or chatter. The various areas of the brain begin to integrate into one whole functioning unit like the masters of meditation. With the DAVID, it is normal for most people to experience that same peace and tranquility of a meditator with only a half hour of use with any of the DAVIDs (Digital Audio/Visual Integration Devices).

AVE is not only valuable for clinical use, but it has done wonders for increasing peak performance. Former Mr. Olympia - Bodybuilder Frank Zane "I'm in the best shape of my life, and one reason is mind machines." Golfer Rocky Thompson attributes his winning of the PGA to using the Paradise. Sports Psychologist, Tom Hawes has used the Paradise in training several golfers in the LPGA. Christine Boudrias attributed her Silver Medal at the Lillihammer Olympics to using the Paradise for relaxing and visualizing. We offer a Special Application Session developed with MindAerobics to assist the user to effectively tap into his/her potential to strengthen the mind to get the most out of physical abilities.

Michael Hutchison, author of Megagrain states, "In fact out of all the mind machines I have evaluated, the DAVID is the one that I keep by my bed for my own light & sound/audio-visual entrainment sessions."

We are continuously researching the effectiveness of using the DAVID for a wide variety of applications, allowing us to prove the technology and secure patents for those applications.

We have combined years of market research and product development to offer you products with features and benefits not seen on "light and sound" devices (which are usually made for entertainment, not entrainment) . All of our DAVIDs meet the necessary Power, Consistency, Frequency and Psychological Compatibility Rules, which are crucial in order for brainwave entrainment to effectively and safely occur. This makes the DAVID devices the most powerful and versatile portable AVE devices on the market today.
