Quick Answer
For survival enthusiasts, the best altimeter training resources include online tutorials, instructional videos, and hands-on practice with a variety of altimeters. Key skills to focus on are understanding pressure references, calculating altitudes, and navigating with an altimeter. Practice with different altimeter models and in various environments is essential.
Understanding Pressure References
To effectively use an altimeter, you need to understand how to set pressure references. This typically involves setting the altimeter to match the local atmospheric pressure at sea level, which is often referred to as Mean Sea Level (MSL) or QNH. A typical MSL setting might be 1013 millibars, but this can vary significantly depending on weather patterns and location. To get an accurate MSL setting, consult a weather forecast or use a barometer, then set the altimeter to match this value.
Calculating Altitudes and Navigating
Once you have an accurate pressure reference, you can start using the altimeter to calculate your altitude and navigate. To do this, simply note the current altitude reading on the altimeter and compare it to your surroundings. If you’re in a mountainous area, use landmarks and the altimeter reading to estimate your distance from the peak. For flat terrain, use the altimeter to determine whether you’re ascending or descending.
Practice and Familiarization
The key to mastering an altimeter is practice and familiarity with the device. Start by practicing in a familiar environment, such as a local park or trail, and gradually move on to more challenging terrain. It’s also essential to practice using different altimeter models, as each may have unique features and settings.
