I consider having whistles in the survival kit as a valuable item. Whistles can be used in handy during critical situations without relying of modern systems. Through whistles you can draw attention to yourself if you are ever attacked or need help.

Is there anyone using whistles in their survival kit, have you ever used it for your safety.

I've got a whistle in my pack...It's actually better than calling for help since it's louder and you can only yell for so long before your voice gives out.

If it's in your pack, but you don't know how to use it...it's useless. So, always test your skills as a form of preparation...Don't wait until your life depends on it. That's a lesson you don't want to learn the hard way.

It is a good item to have in a wilderness scenario although it must be used sparringly and not in inappropriate circumstances

We always carry whistles when we go skiing or hiking. Its a great way to get attention when you require help.
