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.
Predict changing weather patterns using the PRO TREK's barometer. It takes readings every two hours and stores them automatically. It graphically displays the barometric pressure for the past 26 hours. The display ranges from 260 to 1,100 hPa/mb (7.65 to 32.45 inHg) with changeovers from hPa to inHg.
- In some areas, barometric pressure is epxressed in millibars (mb) instead of hecto-pascals (hPa). It really makes no difference, because 1hPa = 1mb.
- You can select either (hPa) or inches Hg (inHg) as the display unit for the measured barometric pressure.
