There are many reasons for making a mountain tour equipped with an altimeter. When you're hiking in the mountains, it can be easier to navigate if you know the altitude. Especially when your sight is affected by fog, darkness, or rain. While climbing, you can estimate the approximate distance you have already covered and how far the summit is. However, altimeters serve another far more important purpose when it comes to high-altitude climbing and mountaineering. They can forecast the weather. In fact, a classic altimeter is actually a barometer because it measures the air pressure and uses the information to calculate the altitude. Measuring changes in air pressure is an approach to forecasting weather changes.
Characteristics of modern altimeters
Due to new developments, classic altimeters have become somewhat outdated over the past years. These developments include GPS systems, which offer precise orientation, location determination, navigation aid, and height measurement. Furthermore, many modern outdoor watches have integrated altimeter features, which makes an additional altimeter unnecessary. The renowned watch manufacturer Suunto offers a wide range of such watches. Outdoor watches are very light and small, and can be used to observe the weather just like classic altimeters.
