Wazoo SOS Micro Whistle – Ultra-Loud Emergency Survival
The SOS Micro Whistle is a compact, all-aluminum emergency whistle, engineered for maximum sound output and reliability in extreme conditions. Designed for survival, hiking, and outdoor safety, its lightweight yet durable construction ensures it's always within reach. Attach it, stash it, or wear it, but never leave it behind—this micro whistle holds a hidden life-saving feature true to its name. A must-have for any EDC or survival kit.
When searching for the perfect whistle, Wazoo found that existing options were too bulky, too quiet, prone to failure, or overpriced due to titanium construction. Determined to create a compact, ultra-loud, and reliable solution, they embarked on a months-long study of compressible fluid dynamics—testing tube diameters, chamber lengths, hole angles, and cut depths to fine-tune pitch, volume, and performance.
The result? The SOS Micro Whistle™, engineered for maximum output, minimal size, and ultimate functionality—striking the perfect balance between usability, durability, and portability.
