A diver separated from the dive boat or actually lost at sea can use the sun's light to reflect an intense beam that can be seen from over a mile away in good conditions. The US Air Force survival handbook says the signal mirror is "the most underrated signaling device found in the survival kit." The DiveSoft Safety Signal Mirror is made from polished stainless steel - NOT GLASS - with mirror-like qualities. The diver uses a hole in the middle of the device to aim the signal as required. There is an easy to understand diagram etched into the back side of the mirror with instructions for use. Hopefully you will never need to use this but it is an excellent safety device especially for open water divers that are not in close proximity to a shoreline.

Using a Signal Mirror for Rescue
Because the core of the reflected sunbeam from a flat signal mirror is very narrow, all rescue signal mirrors must include an aiming system. The rearsight aiming system of the signal mirror sold by Dive Gear Express uses a double-sided reflector with a central hole. Such signal mirrors are easy to use, but you should practice aiming to be better prepared to use it in an emergency:
- Hold the instruction side of the mirror approximately the length of the mirror itself from your eye, and face the mirror halfway between the sun and your target.
- Catch the spot of sunlight passing through the central hole on your face, hand, or other surface (the whiter, the better).
- Tilt the mirror so you see that spot reflected in the rear of the mirror.
- Using one eye, sight your target in the very center of the central hole.
- Tilt the mirror so the very center of the spot reflected on the rear of the mirror repeatedly crosses back and forth across the very center of the hole.
- For more help aiming double-sided signal mirrors see the following:
For background on signal mirror aiming methods, see the U.S. Search and Rescue Agency Air Sea Rescue Bulletin (pages 6-11) that includes descriptions of the reflex, rearsight, foresight, and improvised foresight methods along with results from a joint field test by the US Coast Guard and National Bureau of Standards.
