Multi-Pursuit Devices

Patent-pending Specialized Target Optimization™ (STO) is the world’s first hearing technology that isolates and enhances the exact frequencies hunters need to hear for a variety of pursuits: deer, elk, turkey, waterfowl, upland, and range. With STO, voices are clear, signature game sounds are easily audible, and your surrounding environment sounds clear and natural. TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment it’s needed. For more sustained loud inputs, like loud calling, AlphaShield Compression™ limits the overall output to a safe level, then returns to normal amplification once the loud input has stopped. Never miss a sound you want to hear, and protect your hearing for life.
