The DAVID Delight Plus Agytréner device is the mid-range model in the Delight family. It contains a total of 28 audio-visual programs, 3 of which are extra programs. Its large, easy-to-use buttons glow in the dark, so it can easily be used at night as well. Music can be connected to the device’s programs. It is also ideal for those who travel frequently, since it is portable, runs on batteries, and is not damaged by airport security scanners.
The device contains 25 basic programs. To start a program, you simply choose from among the 5 program groups. Each group contains 5 programs.
The program groups:
- Energizing
- Meditation
- Brain-Boosting
- Sleep
- Mood Enhancing
It also includes 3 further programs in the extra program slots, which can be used to achieve block-releasing, harmonizing, and self-healing effects. The remaining 2 free program slots allow further programs to be added.
The Delight Plus device can sync with your favorite music and audio material recorded in digital audio file format. Through this synchronization, the programs can be started in a new mode.
The programs begin with a dissociation segment. Its effect is most similar to the initial relaxing breathing techniques used in meditation. It helps relax the body and detach from the senses. The programs guide the user along the given meditative path, from the waking state through the meditative levels and back to the waking state again. This is why it is also called the AVE technique, audio-visual entrainment, which uses the operating principle of AVS (audio-visual stimulation).
The programs have undergone thorough testing and are based on the latest research findings, so their use is safe and effective. The patented TruVu glasses make it possible for the program to guide the two brain hemispheres with different frequencies, achieving an even more refined effect and greater results.
The device’s programs also include an HRV function. It helps keep breathing at the proper rhythm, which significantly calms both the sympathetic and parasympathetic nervous systems.
Successful scientific studies have been conducted with DAVID Delight devices in the following areas: seasonal depression, stress reduction, insomnia, mood improvement, mental sharpness, balance improvement in the elderly, anxiety reduction, and concentration and memory improvement in university students.
