Quick Answer
When selecting a baseplate compass, look for a durable, water-resistant design with a clear, adjustable declination correction and a reliable magnetic needle. A scale for measuring latitudes and longitudes is also beneficial. Additionally, consider a compass with a built-in clinometer.
Essential Features for Navigation
When choosing a baseplate compass, consider the type of terrain you’ll be navigating. For example, a compass with a magnifying glass can be useful for navigating in dense forests. A rotating bezel with degree markings helps with accurate navigation. A baseplate compass with a sighting mirror can also help with reflecting sunlight to signal for help.
Declination Correction and Accuracy
A reliable declination correction feature is crucial for accurate navigation. Look for a compass with a clear and adjustable declination scale. This feature allows you to compensate for the difference between magnetic north and true north. A declination correction of up to ±20° is usually sufficient. A good baseplate compass should have a stable and reliable magnetic needle that can be adjusted to compensate for declination.
Additional Features for Enhanced Navigation
Some baseplate compasses come with additional features such as a built-in clinometer, which measures the angle of elevation or depression. This feature is useful for navigating steep terrain or estimating the height of an object. A baseplate compass with a scale for measuring latitudes and longitudes can also be beneficial for navigating in unfamiliar areas.
