Be aware Wich that this is one persons opinion! Also almost all the authorities in Electro healing use the FSCAN and for DIRP. Many electro healers do not use the Fscan for therapy i.e using its contact john crane style contact system, they use external Rife machines like EMEM, BARE. So I suggest you ask people like Dr Jeff Sutherland his opinion of the FSCAN 2 and people who have had success using the DIRP on friends with illnesses before you take one persons view.
