Quick Answer
For measuring compass bearings in snow, a clinometer and a Suunto compass with a rotating bezel are the best tools. The clinometer measures the angle of the slope, while the Suunto compass provides precise direction readings. Together, they help navigate through whiteout conditions.
Choosing the Right Clinometer
When selecting a clinometer for snow navigation, look for one that measures inclinometer readings in degrees (-90 to +90 degrees) and provides precise measurements. A clinometer with a built-in level and an adjustable zero-point setting is ideal. Some popular clinometer models include the Suunto Clinometer and the Silva Clinometer. Use the clinometer to measure the angle of the slope, taking note of the direction (up or down) and any obstacles that may be in your path.
Using a Suunto Compass with a Rotating Bezel
A Suunto compass with a rotating bezel is essential for precise direction readings. When navigating through a whiteout, orient the compass using the inclinometer to determine the direction of the slope. Rotate the bezel to align the direction-of-travel arrow with the desired direction. Take note of any landmarks or features that can help guide you in the right direction. The Suunto A-10 and Suunto M-3 Global are popular compass models that feature rotating bezels.
Techniques for Snow Navigation
When navigating through a whiteout, use natural features such as tree lines, ridges, and valleys to help guide you. Take regular bearings to stay on course, using the clinometer to measure the angle of the slope and the Suunto compass to determine the direction. Consider using a map and compass together to stay oriented, using the clinometer to measure the angle of the slope and adjust your course accordingly.
