The Rich-Mar Theratouch 7.7 is the top of the line model for Rich-Mar. It basically combines a Theratouch 4.7 stimulator and a Therasound 3.5 ultrasound. You have the easy touchscreen operation combined with four independent stimulation channels and the "Therapy Hammer" soundhead providing 1 & 3 MHz ultrasound. A truly flexible piece of therapy equipment, the Theratouch 7.7 allows for up to five different sites to be treated at once. Also, its upgradeable design has made the device actually improve with age.
