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.

Altimeter

Use the PRO TREK's altimeter to help gauge the time you'll need to reach the summit! The altimeter checks and displays the altitude every two minutes, and stores readings with the temperature every 15 minutes. The graphing function positions you with respect to your target altitidue, with alarm alerts you as you approach your mark.

The measuring range is from -700 to 10,000 meters (-2,300 to 32,800 ft.).

Quick Facts

  • Altitude is displayed in units of 1 meter (5 feet) or 5 meters (20 ft) depending on model.
  • The measurement range is -700 to 10,000 meters (-2,300 to 32,800 feet).
  • You can use the historical record to keep track of high altitude, low altitude, total ascent and total descent values.

Altimeter  

Measuring altitudes based on changes in atmospheric pressure

Pro Trek Atimeter Graph

The altimeter determines the altitude at your current location based on accumulated atmospheric pressure changes measured by the pressure sensor. Setting the altimeter at a location where you know the precise altitude before starting your ascent enables it to take even more precise altitude measurements.

Sea level measurement

Setting the altimeter at a location where you know the precise altitude enables you to determine the elevation of your current position with respect to sea level. If you come across a marker indicating 400 meters above sea level while hiking or climbing, for example, simply set the altimeter at 400 meters. This enables you to obtain more accurate readings with respect to sea
