Electronic circuit allows synchronization of one's brain waves to produce controlled states of relaxation or weird and bizarre hallucinations.
The MIND20 includes a sensor that adjusts the pulse rate according to perspiration, effectively acting as a feedback loop for self-hypnosis or self-therapy purposes. The HYP20 does not have this feedback-loop sensor, and is better suited to another's controlled use like with a therapist.
Simple to adjust and use.
