Specialized Target Optimization™ (STO) is the world’s first hearing technology that isolates and enhances the exact frequencies hunters and shooters need to hear. We analyzed the acoustical properties of game vocalizations, calling, voices and shooting to develop this patent-pending sound processing system.

STO is pursuit specific.

Waterfowl devices make voices in the blind and calling clear and natural, wings-whistling, wood duck squeals and mallard drakes easily audible, and loud-calling and shotguns safe.

Turkey devices make gobbles and yelps louder and clearer for better detection, distance judgement, and direction.

Elk devices make bugles, grunts, and barks louder and clearer for better detection, distance judgment and direction.

Deer devices accentuate the sounds of deer movement and vocalizations.

Upland devices enhance bird flushes, dog ecollars, and cow bells.

Range devices are optimized for the most critical sounds for the shooter, while providing hearing protection from gunshots. 

You can even get Multi-Pursuit devices that have programs for each pursuit.
