Description
⚠️ WARNING: EXTREMELY LOUD.
To prevent permanent hearing damage, please use proper hearing protection (earplugs) when testing or blowing this whistle.
Designed to maximize air velocity for maximum impact. This 30mm x 10mm x 4mm whistle blasts a commanding, piercing 120dB+ dual tone. By utilizing dual chambers, it generates a richer acoustic frequency that travels significantly further outdoors than any standard single-pitch whistle.

Print & Calibration Notes: The intricate dual chambers require a highly accurate print to function properly. Ensure your filament flow is perfectly calibrated. These were successfully tested using manually tuned SUNLU High Speed PLA+ 2.0, sliced for a 0.4mm nozzle, 0.4mm line width, and a 0.1mm layer height.
