Signal Mirror — Military-Spec Glass Retroreflector for Emergency Signalling

In an emergency where your radio and phone have both failed, a signal mirror can be seen from a search aircraft up to 16 kilometres away in direct sunlight. No batteries. No moving parts. Infinite service life. The retroreflective aiming aperture allows precise aiming directly at an aircraft or rescue team even when you can't directly see your reflection — critical when the sun is low or at an angle.

This military-specification borosilicate glass mirror is more durable and optically precise than acrylic alternatives. The anti-glare matte rim prevents false signals. Lanyard hole for belt or pack attachment. Weight is negligible — there's no reason not to carry one in every emergency kit, vehicle glove box, and aircraft survival kit.
