Fire in daylight. It wouldn’t be so effective right since everything else would be pretty much lit by the sun? Well, not really. Now while visually, the light of a fire wouldn’t be near as half as good if it were used at night, as it wouldn’t stand out as well, the smoke a fire creates can step up to the plate and be a real eye-catcher.
A fire can be an effective means of visually signaling others: be it used at night or even day (smoke signal). This is why we’re going to teach you fire signaling for survival situations.
Having the means to communicate can be a big thing if placed in any survival scenario. How would potential rescuers know you’re there? How would you then have an exchange of information between allies if supplies and gear are scarce?
