Description
This is one of the things we hope you never need it.
But they are so small and cheap, you can get them anything.
This is a very large whistle that can be carried at any time and can be used if you need to ask for help (hoping it wasen).
It is no doubt that people have seen a TV show for help, but if you have to shoot loud for help, we also know that your voice will be gone.
However, as long as you can blow this whistle, you can draw attention from anyone in your ears shot. This is a whistle, and probably be far away than your voice.
If you know the Morse signal, you can even send a message. The easiest message to remember is the International SOS encounter signal. Continuous sequence of 3 points (short sound), 3 dashes (long sound), and 3 dots (short sound). It will immediately recognize and attract the attention of anyone who can listen to it. They can use it to find you and come to your rescue.
There is nothing to measure the decibel level that is emitted, but it is definitely loud to prove it!
