Quick Answer
To send a distress signal on land, use any means possible to signal your location, such as whistling, flashing lights, or setting fires. Fire three shots from a gun or shine a flashlight in an SOS pattern (three short flashes, three long flashes, three short flashes) to signal distress. This can be done in conjunction with sending a radio signal.
Preparing a Distress Signal
When preparing a distress signal on land, it’s essential to use any available materials to increase visibility and audibility. This can include setting fires, using flares, or creating a smoke signal during the day. At night, use flashing lights or lanterns to signal your location. If you have a whistle, use it to signal your location by blowing three short blasts, followed by a pause, and then three more blasts.
Sending a Radio Distress Signal
To send a radio distress signal, use a handheld radio or a two-way radio to call for help. Start by calling out on channel 16 (the international distress frequency) and then switch to channel 9 to alert anyone in the area to your presence. Use a clear, concise voice to give your location, the nature of your distress, and any other critical information. Use a loud, clear voice or a loudspeaker to ensure your signal is heard by others.
Essential Distress Signal Techniques
When sending a distress signal, use the following techniques to maximize your chances of being seen or heard: use high ground for visibility, stay in the open to reduce obstruction, use a signal mirror to reflect sunlight towards any potential rescuers during the day, and use a smoke signal or fire to signal your location at night. If you have a compass, use it to estimate the direction of any rescue teams and signal in that direction.
