A surface marking device such as a SEE/RESCUE.1 device is a superior alternative to a dye marker.  The SEE/RESCUE. device is a long buoyant plastic banner, which when unrolled, floats on the surface.  It is very easy to see and does not disperse from the action of the sea.
 
D.8.  Pocket Strobe
 The pocket strobe should be used only at night and when aircraft or vessels are seen or heard.  The batteries on the pocket strobe have a limited effective life of about 10 hours.  For best visibility, the strobe should be positioned as high as possible.
 
D.9.  Whistle
 Over the water, the sound of a whistle can be heard for a much greater distance than voice alone.  Using the whistle also requires less effort and can be sustained for a longer period than can shouting.
 
D.10.  Space Blanket
 The orange side of any space blanket, typically provided in the survival pack, should be spread to enhance visibility when search units are seen or heard.
 
D.11.  Exposure to Sun, Wind, and Salt Water
 Exposure to sun, wind, and salt water should be reduced to the extent possible.  Even in the tropics, all clothing should be saved and worn as a cover to protect you from the rays of the sun.
 
D.12.  Hypothermia
 Hypothermia is a danger even in relatively mild weather.  In cold weather, survivors should huddle together under the raft cover, wearing dry clothing if possible.  Use space blankets to retain body heat and to break the cooling effect of the wind.  Try to keep the raft dry.  Even when in the water, swimming is generally not recommended.  The loss of body heat during swimming is considerably greater than remaining in the huddle position floating in a PFD.
Keep all clothing on including shoes or flight boots, since clothing helps to contain body heat.  It is important to keep heads out of the water, as it is one of the areas of a person’s body through which considerable heat can be lost.  If a hat is available, it should be worn.  Consider including some very large plastic garbage bags in the survival kit.  If in the water, step into the bag and pull it up around the legs and torso.  The bag will trap a boundary layer of water near the body.  This will serve as another insulating barrier and will reduce heat loss to the open water.
