Meet the SOS Micro Whistle, an all-aluminum whistle, designed to minimize size, maximize output, and function reliably under the most extreme conditions. Attach it, stash it, or wear it, but make sure you bring it on every adventure since this durable micro whistle is actually designed with a hidden life-saving capability *hint* it's in the name *hint*.

  • Dimensions: 8.5mm Diameter x 43mm Long   (~0.33" x 1.7")
  • All Aluminum Construction (No Plastic Here!)
  • Wide Range of Function
  • Starts Resonance at Low Flow (good for kids) and Can't Be Over-Blown (good for adults)

The story of design and development behind this little screamer makes it a must-have for every kit and keychain.

There was not an existing whistle on the market that could live up to Wazoo's stringent requirements. They were too bulky, not loud enough, had parts that would fail, or were insanely expensive because they were made from Titanium. In a months-long experiment of compressible fluid dynamics, we tried every tube diameter, chamber length, hole opening angle, and cut depth. Each variable was tied to the next and as a group, they controlled the pitch, volume, ease of use, and ability to "over-blow" and max out the whistle. This SOS Micro Whistle™ is the culmination of all that research. It is balanced on the razor's edge of usability, functionality, and compact size.

Excellent

Just what I was looking for. Very loud, small and lightweight. I have it on a neck chain along with a small flashlight.
