Pro Trek V.3 Triple Sensor Engine
The new triple sensor has Improved accuracy, is 95% slimmer, and uses 90% less power. Three high-sensitivity miniaturized sensors take accurate measurements of constantly changing natural phenomena, and display directions, differences in altitude, and atmospheric pressure tendencies in both digital and analog formats as well as temperatures in digital format.
Three minature sensors for measuring directions, barometric pressure/altitude, and temperature:
These compromise PRO TREK's core technologies for high-precision detection of sudden changes in natural phenomena.
In 2013, CASIO developed a dramatic upgrading of Triple Sensors with its advance to 3rd generation.
