The Pointer Excel II is the latest and most advanced user friendly hand held locator and stimulator. Features a built-in, 0.35"x 1.0"LCD digital meter which displays both frequency and location. The meter reading increases in relative value from 1 to 500 (at max sensitivity setting) due to a lowering of the electrical resistance of the skin at the treatment location. Besides the meter, location is also indicated with sound and a pilot light on top of the unit. Location sensitivity is adjustable. An effective push button adjustable stimulation offers immediate treatment. Based on the setting of the output dial, either normal milli-amp output or micro-amp current output is produced (ie, blue zone on the dial is microamp).
