Silva Forecaster compass

The Silva Forecaster is a minimalist clip-on compass rather than a primary navigation instrument, weighing just 14 g and designed to attach directly to a pack strap or jacket zipper. Silva, a Swedish compass maker founded in 1933, builds it around a fixed dial with no declination adjustment, so readings need manual correction for magnetic declination depending on location — a limitation worth knowing before relying on it in areas with significant declination. Its main extra feature is a built-in thermometer reading in both Celsius and Fahrenheit, paired with a wind chill reference chart, which turns the compass into a quick weather-check tool as much as a direction-finder. It has no luminous markings, so it isn't meant for night navigation, and the clip-on design trades map-and-compass precision for grab-and-go convenience. Given its size and lack of declination correction, this suits hikers who already carry a full baseplate or mirror-sighting compass and want the Forecaster as an always-on backup, or as a simple always-accessible way to check direction and temperature at a glance rather than plot precise bearings.
