That's what we've named our latest addition to the DAVID family, the DAVID PAL™(Portable And Lightweight). We're very excited about our latest creation with our newest and best preset sessions programmed into it and it's half the size of our other audio-visual entrainment models. It even has heart rate variability (HRV) to help you breathe as well as a meditator can.

The DAVID PAL™ is an extremely portable audio-visual entrainment device. This is the one that will fit in your shirt or jacket pocket (approximate dimensions - 2.5 x 1 x 3.5 inches / 7 x 2.5 x 9cm ) and will allow you to experience audio-visual entrainment wherever you go. Perfect for people who are on the go.

SPECIAL FEATURE

One of the special and unique features of the DAVID PAL™ is that it has charging capabilities. The DAVID PAL™ can charge rechargeable batteries and even your alkaline batteries when you're not using the DAVID PAL™. You just simply set the ON/OFF/CHARGE switch to charge mode to recharge your batteries.

BRAINWAVE ENTRAINMENT

To ensure safe, gentle and effective brainwave entrainment, the DAVID PAL™ offers the following:
Tru-Vu Omniscreen™ Eyesets - Our unique Tru-Vu Omniscreen™ eyesets were carefully designed to provide you with the most effective and safe light and sound experience. The Tru-Vu Omniscreen™ eyesets use eight high efficiency white bulbs mounted over a silver reflector behind a light blue-tinted translucent screen. This disperses the light evenly, protects the bulbs and removes any red light which may be produced by the bulbs. White light has proven most effective in imagery, relaxation and visualization. Our new Tru-Vu Omniscreen™ eyesets are specially designed to allow for the left and right visual fields of each eye to be individually stimulated rather than the entire eye. With the Tru-Vu Omniscreen™ eyesets, the lights flash into the left visual fields of both eyes, then alternately flashes into the right visual fields of both eyes. This approach allows the ability to stimulate either visual cortex with a frequency different from the other visual cortex. For example, a person who functions strongly from the left brain could have 8 Hz stimlulated into the right visual field (and therefore the left brain) to slow down left brain function and have 18 Hz stimulated into the left visual field to increase right brain function.

Isochronic Pulsed Tones - The tones of the DAVID PAL™ are evenly spaced, are of equal pitch and are turned on and off at a specified rate. This is important to enhance the effectiveness of audio entrainment.

Soft-Off™ - The gradual lowering of the light stimulation at the end of the session prevents a startle response (also known as somnatic shock). Soft-Off™ ensures that relaxation and other benefits carry over even after a session.

Easy-To-Find Intensity and Select Buttons - Both the select button and the intensity button are raised so that you can make the necessary adjustments easily and quickly. Adjust the intensity of the Omniscreen eyeset with the easy-to-find INT button. Simply press the SEL button to select which preset sesssion you wish to run.

18 Preset Sessions - Including Brain Brightner (for ADD and cognition), Fractioned Hypnosis, Alpha/Beta Mix (for depression), Schumann with Dissociation & HRV (for meditation), Beta Perker, Theta with Dissociation (for sleeping), and Music Modulation (to turn your music into an intriguing light show). 18 Preset Sessions

HEART RATE VARIABILITY (HRV)

For the first time, a system exists where meditative breathing may be paced along with an audio-visual entrainment (AVE) session. This technique has been borrowed from our clinical model, the DAVID Paradise XL™. Long, graceful breathing cycles have been used as part of meditation. Scientifically, this technique has been analysed and shown to settle down a stressed autonomic nervous system. Both sympathetic (flight-or-fight) activity and para-sympathetic (the brain’s efforts to compensate) activity settle down dramatically using HRV techniques.

The heart speeds up with every breath in and slows down with every breath out. This swing in heart rate is HRV. A typical heart beat swing is in the order of about 15 beats per minute (pbm). When people get stressed, the heart typically clamps to sometimes as low as five bpm HRV at times intermixed with sharp spikes in heart rate. This is all abnormal activity and is rough on the heart.

The HRV technique used clinically is based on a 10 second breathing cycle (six breaths/minute, by inhaling slowly for five seconds and exhaling slowly for five seconds in an easy, relaxed breath). When using HRV paced breathing, listen to the heartbeat generated by the DAVID PAL™ through the headphones. Inhale for two heartbeats and exhale for two heartbeats (not your own heartbeats!). Most sessions begin at seven breathing cycles/minute (28 heartbeats/min) and slow to six breaths /minute (24 heartbeats/min). This allows the user to breathe a little faster at the onset of a session until he/she has had time to relax.
