The Heliograph (Mayday Signaling Mirror) is a compact emergency signaling device designed for marine, military, and outdoor use. Its highly reflective surface allows sunlight to be directed toward rescuers, aircraft, boats, or other targets during emergency situations.

The mirror is designed for one-handed operation and features a central aiming point to help direct the reflected light accurately. It floats if dropped into water, making it particularly suitable for marine environments and water-based emergency kits.

Instructions are printed on the reverse side for quick reference, allowing the mirror to be used without complicated setup. Its compact 10 cm size makes it easy to include in life rafts, lifeboats, emergency kits, backpacks, and other outdoor equipment.

The supplied product information states that the mirror can provide visibility over distances of more than 16 km (10 miles) and carries NATO Stock Number (NSN) 6350-99-613-9818.
