In case there is an emergency when in an unknown area, it is extremely important that you have worked out ways to communicate in an emergency with your party. Most people prefer to use battery operated radios to be able to communicate back and forth, and this is the most effective way to communicate. However, if your batteries die, you should work out an alternate method of communication.
Other ways to communicate in an emergency include the use of whistles. While this can be a bit confusing, you should focus on a few easy to remember whistle patterns and meanings. At least you will be able to find each other if you get lost. Bright colors are also very useful, but only if you are going to be in a relatively small space. Any time you go out into the wild, it is very important that you take a flashlight for emergency purposes. You should avoid the battery operated ones, as they are less effective. You should get one of those flashlights that is powered by you shaking it, so it will never run out of juice.
