TRIPLE SENSOR TECHNOLOGY VER.3

Triple Sensor, Ver. 3

Three miniature sensors for measuring directions, barometric pressure / altitude, and temperature: These comprise PRO TREK’s core technologies for high-precision detection of sudden changes in natural phenomena. In 2013, CASIO has developed a dramatic upgrading of Triple Sensor’s with its advance to a 3rd generation.

Triple Sensor’s History of Evolution

Triple Sensor, Ver. 1 (1994-2001)

Triple Sensor debuted in 1994. Operating on battery power, it revolutionized the wristwatch with its ability to measure directions, barometric pressure / altitude and temperatures.
