We Use State-Of-The-Art Computerized Polygraph Equipment

 

Important Information: In addition to conducting professional polygraph examinations, we are a licensed, full-service, fully staffed, investigative agency.  Our polygraph examiners are experienced investigators - most have extensive law enforcement experience.

Our trained and certified polygraph examiners conduct the polygraph examinations.  During the truth verification process, computerized polygraph instrumentation is utilized, in conjunction with pre-test and post-test interviews.

The term "polygraph" means "many writings", and various physiological activities are recorded.  The polygraph instrument records changes in cardiovascular, respiratory and electrodermal patterns.  The polygraph recordings are reviewed and analyzed by the examiner, and a professional opinion is rendered based on the polygraph recordings.
