The Coghlan’s Emergency Survival Horn is very loud! It operates with the simplicity of a mouth horn and blasts out audible sound up to 120dB. The membrane can be easily replaced with any thin flexible film. Comes with SOS printed on the body and a black break-away lanyard.

• Features a stone and twig guard to protect the rubber membrane and comes with a break-away lanyard.
• Durable polypropylene construction floats and is easily seen with the blaze orange color

Blow into the small hole located on the side of the horn. The blast of sound will exit through the back of the horn through the dual chamber horn.
