Let's set the record straight: elk hunting without proper ear protection causes hearing loss. As hearing doctors at TETRA, we witness the impact of years of hunting on our patients' hearing. Recent studies indicate that people with hearing loss are more likely to develop dementia, Alzheimer's, and other chronic health issues. Hearing loss affects overall health and wellness and diminishes the hunting experience.

So why do 86% of hunters avoid using hearing protection? Previous products distorted the sound of the call, either by over-amplifying everything or blocking out your surroundings, and often lacked comfort. We've addressed these issues with the TETRA Shield Series. Our patent-pending Specialized Target Optimization (STO) ensures voices and calls sound clear and natural, while AlphaShield Compression reduces loud noises to safe levels.

AlphaShield is a small, extremely comfortable, one-size-fits-all solution. It offers excellent comfort and protection without requiring an ear impression.

TETRA isn't just hearing protection; it's hearing perfection.
