carabiner compass

Common mechanisms are liquid-filled luminous compasses and ball compasses; they provide cardinal points and a direction-of-travel readout.

Some models include a fold-away 3× magnifier (a 3X magnifying glass that folds away to avoid scratches).

Typical dimensions are about 2.5–2.9 inches long and 1.5–1.6 inches wide, with a weight of roughly 0.05–0.07 pounds.

They commonly include an aluminum carabiner clip and many models also come with a split ring (some specify a brass split ring) for attaching to zippers, keychains, or packs.

No. Product details state they are not for load-bearing use.

Features include a ball compass that's readable at any angle and shows cardinal points and a direction-of-travel card; some dual-card designs show general orientation when viewed from above and the direction of travel when held at eye level.
