You've seen all the websites<br>"loudest whistle in the world guarunteed"<br>BUT which whistle is most effective i.e. For x amount of effort i get most decebals!!! <br><br>NOT BOTHERED ABOUT SIZE - it's for my rucksack as a backup to my EDC one and PSK one!!!<br><br>Thanks

If you are not bothered with the size I would say Fox Storm. I had the chance to use it on few occasions and it was worth the money I paid for it.<br><br>Be careful with it and do not blow without noticing people around :)<br><br>Burak<br>Istanbul

I have used both the Fox40 and the Storm. I think the Storm whistle is louder, but it is about 4 times bigger than the Fox. I carry a modifed Fox (see Doug's instructions) around my neck and in my PSK. I keep a Storm in my Daily carry kit, coat pocket and CERT response kit. I find the Storm great for canoeing, backpacking etc, but too bulky for EDC.<br><br><br><br> Storm Whistle
