De BERRT lijkt sept 2010 niet meer te worden verhandeld. Maar de site kent wel weer andere Rare Apparaten:

The BERTT is similar to a Syncrometer, also spelled synchrometer or electrodermal testing (EDT)
....
In the "test mode", the instrument identifies acupuncture meridian points using electrodermal testing and quantises the energy with the sensitive digital meter (0-1000) and an internal audio oscillator. In the "treat mode", the gold-plated probe treats with microcurrent, the intensity of which is controllable from 0 to 2000 microamperes (2 mA). Simultaneous pulsed light is emitted from the probe. Our experiments have indicated that this is an Intention Imprinted Electronic Device (IIED) such as described by Dr William Tiller
