Tam C3 (formerly known as Betavan version 3), a 4-way version of the Tam device series, which has the ability to record 4 protocols Alpha, Tetha, Delta and Mid-Beta at the same time. These 4 main protocols of Tom technology provide the user with the possibility of improving and treating a wider range of disorders. In the C3 version, there is a possibility of personalization and the user can personalize this device according to his needs by preparing a brain map to bring the best performance of the device. Tam's series of devices with technology (Li_RTMS Low intensity repetitive transcranial magnetic stimulation) can stimulate brain cells by introducing electromagnetic waves. As a result, stimulation of brain cells by decreasing or increasing the activity of brain cells will eliminate disorders in time. Unlike the two more basic versions of the device (models C1, C2), the C3 version cannot be used without electricity and must be connected to electricity during use. This device can help to treat and improve a problem and after solving the user's problem, he can put different protocols on the device at a separate cost or personalize the device for someone else.
