E-FIT has developed a reputation as a highly reliable and flexible system for feature-based composite construction.
The system is available in Spanish, German, English (both US and UK), French, Italian, Portuguese and Swedish.
The widespread use of the original E-FIT approach is gradually being superseded by a new version of the program called EFIT-V. EFIT-V is a full-colour, hybrid system that offers increased flexibility and speed, allowing the face to be constructed using both evolutionary and systematic construction techniques.
The E-FIT, Pro-fit, and similar systems used in the UK have been subjected to a number of formal academic examinations.
However, one study found that if witnesses were required to wait two days before constructing a composite, which matches real-life applications more closely, success rates fell to between 3 and 8 per cent.
