Quick Answer
To improve the visibility of your smoke signal, use dry, green wood and aim for a high, thin column of smoke. This can be achieved by building a teepee-shaped fire and using a slow-burning, well-oxygenated fire. You can also use signal flares, which are more visible than smoke.
Choosing the Right Signal Flares
When selecting signal flares, consider the environment and the time of day. In low-light conditions, use flares that emit bright, long-lasting lights, such as magnesium flares, which can burn for up to 50 seconds and produce a light output of 100,000 candelas. In daylight, use shorter, more intense flares like phosphorus flares, which burn for 20-30 seconds and produce a light output of 50,000 candelas.
Building a Signal Fire
To create a visible smoke signal, build a fire in a clear area and use dry, green wood. Aim for a high, thin column of smoke by building a teepee-shaped fire. Place the flammable material in the center, then surround it with green branches. As the fire burns, the green branches will smolder and produce a steady stream of smoke. Keep the fire small and controlled to maintain a high, thin column of smoke.
