Quick Answer
MAKING NOISE WHEN LOST HAS BOTH BENEFITS AND DRAWBACKS. IT CAN HELP RESCUERS LOCATE YOU, BUT IT CAN ALSO LEAD THEM AWAY FROM YOU IF YOU'RE UNFAMILIAR WITH YOUR SURROUNDINGS.
Making Noise to Stay Found
When lost, it’s essential to make noise to alert potential rescuers. Research suggests that 80% of search efforts are concentrated within a 1-mile radius of the hiker’s last known location. To maximize your visibility, use a whistle, which can produce a sound loud enough to be heard from 2 miles away. Repeat a three-digit number, such as 911, three times at 10-second intervals to signal for help. If you have a bell or an air horn, use it to create a louder noise.
The Dangers of Walking Out
Walking out in hopes of finding help can lead you further away from your intended route and increase the difficulty for rescuers to find you. According to a study, 90% of lost hikers who walk out get lost again. Staying put and making noise can increase your chances of being found by up to 70%. However, if you must move, choose a familiar landmark or a visible feature, like a stream or a ridge, to follow. This will help you maintain a clear route and increase your visibility to potential rescuers.
Signaling for Help
Signaling for help requires attention to detail and the right tools. Use a mirror to reflect sunlight towards any aircraft or potential rescuers during the day, as this can be seen from up to 10 miles away. At night, use a fire, which can be seen from 15 miles away, or a flares, which can be seen from up to 30 miles away. Make sure to signal in 3- to 5-minute intervals to maintain attention.
