Quick Answer
When selecting a survival altimeter, look for features like precision, battery life, and rugged construction, as well as the ability to set altimeter modes and display data like barometric pressure and temperature. The device should also have a clear and easy-to-read display. Additionally, consider the altimeter's weight and size.
Altimeter Precision and Accuracy
A survival altimeter’s primary function is to accurately measure altitude. Look for a device with a precision of ±5 meters or better. Some high-end altimeters even offer precision as low as ±1 meter. This level of accuracy is crucial for navigation, especially in areas with complex terrain.
Additional Features and Modes
In addition to altitude measurement, a survival altimeter should offer various modes and features to enhance its functionality. These may include barometric pressure and temperature readings, which can help track weather patterns and potential storm systems. Some altimeters also offer a “climb rate” mode, which displays the rate at which you’re ascending or descending. This feature is particularly useful for pilots, but can also be beneficial for hikers and climbers.
Display and User Interface
A clear and easy-to-read display is essential for a survival altimeter. Look for a device with a high-contrast display that can be easily read in a variety of lighting conditions. The user interface should also be intuitive and easy to navigate, with buttons or controls that are simple to operate with gloves or in cold conditions. Consider an altimeter with a backlit display, which can be a lifesaver in low-light situations.
