Equipment - A small distress signaling device which enables sun reflection to be accurately directed to ship or shore in case of emergency

Historical information

Distress signalling device from the SS Time.

5. Mirrors: Better known as a Heliograph, a mirror might be used while onboard and mostly on a survival craft to reflect the sunshine towards the entity that one needs to attract the attention of. These mirrors not only reflect the light to pinpoint the location of the emergency but are also non-corrosive at the same time. This helps to prolong their usage for a longer period of time.
