In the course of the amazing growth of science and technology over the last half-century, using technology in designing new methods of teaching movement skills has improved the performance of champions and led to setting new records. The present study aims to produce and assess the photo finish devices and compare the results to those of the manual measurements in the track and field tests. In order to do so, the photo finish device was designed and constructed as a portal. Afterward, the results of athletes’ performances in a track and field test were recorded simultaneously by both a photo finish device and a handheld stopwatch. Dependent T-test was used so as to compare the results of both measurement methods. Results showed, that there is a statistically significant relationship between the average of obtained records from time measurement via photo finish devices and handheld stopwatch (t= -11/99, P= 0.0001).
