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.
You can record up to 40 sets of data with each record displaying the altitude, month, date and time. The measuring range is from -700 to 10,000 meters (-2,300 to 32,800 ft.).
• Altitude is displayed in units of 5 meters (20 feet).
• 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.
