How accurate is the Vertech Altimeter function? How does this compare to other altimeters?
The accuracy of the Vertech altimeter is the same as the accuracy of aircraft altimeters. There are two components of altimeter accuracy: FIRST, the accuracy of any altimeter depends on the USER. To get the best accuracy, an altimeter must be ADJUSTED at a known elevation regularly. The more frequently adjustments are made, the more reliable the altitude information will be. A Vertech that has been recently adjusted can be taken to different elevations and will usually be correct to within about 30 feet. A Vertech (or any altimeter) that has NOT been adjusted for more than a day may be in error by up to several hundred feet, depending on weather changes since the last adjustment.
