Signal, Day/Night, MK.4

THE MK-4 DAY/NIGHT FLARE IS A DISCONTINUED ITEM.

SEE DAY/NIGHT FLARE, DISTRESS SIGNAL, (PART NO. SIG-913-1500) AS A SUITABLE ALTERNATIVE.

 The MK.4™ Day/Night Signal Smoke was designed as a compact personal distress signal for naval divers and aircrew. It should be carried in any situation where a robust and waterproof personal distress signal may be required. The MK.4 is particularly suitable as a signal for divers who may accidentally surface away from their support craft. Waterproof down to 30 meters, it has a corrosion resistant case with 'O' ring sealing.

This dual-purpose signal consists of an orange smoke signal at one end for use by day and a red flare at the other end for use at night. Protected by interchangeable end caps, the signal has tactile ribs at the flare end to aid identification by night. The smoke and flare are operated independently and use of one does not affect the functioning of the other at a later time. NSN: 1370-99-346-8905
