Linear / Non-Linear scan of the laser pulses (some refer to as Hz's) is an option for an additional fee at time of purchase. Linear or non-linear scan allows you to set a range.
As an example: 15 for the first setting and 512 for the second setting. If that range (15-512) was set on linear it would scan from 15, 16, 17, 18 etc. every second in numerological order up to 512 and then reciprocate in a linear rhythmic fashion. Linear scan would commonly be used as an amplifier when using brain settings such as alpha, beta, delta, theta, gamma. Or any other condition in the body that you determined may benefit.
NOTE: the body has so many physiological functions going on at once and the body loves rhythms! Cross crawl, brain waves, digestion, hormones, immune system.
VibePlate and the unique "synchronous vibration wave" is a great neural Brain/Body integration for any clinician and laser practitioner.
