The harder you blow, the louder the sound! It will be heard above ambient noise, the roar of engines, breaking waves and thundering gale-force winds. The chambers are designed to self-clear when submerged in water. There are no moving parts to freeze, jam or deteriorate.
Design: 3-chamber pealess
Sound Power: 115 dB
