Gun Dog Training CustomShield $1,999.00 / Pair

Before Tetra, it was always a hassle juggling earplugs to shoot and use launchers but still needing to communicate with other trainers. Now, not only is my hearing protected but it's easier to coordinate with the other people in the field. Not having to always look for earplugs saves me time that I can use to focus on making better gundogs.

At TETRA, we used our patent-pendingĀ Specialized Target Optimizationā„¢ (STO) to isolate the exact frequencies associated with a variety of pursuits and created custom programs to enhance the sounds you most need/want to hear - like voices, duck calls, and flushing birds - and protect you from those you donā€™t, like loud gun shots. Now, with ourĀ gundog device, you can getĀ custom programming in one convenient device, and changing between programs is as easy as one simple tap.

TETRA isnā€™t just hearing protection, itā€™s hearing perfection.

  • Custom-molded to the exact shape and contour of your ear

Our Technology

Specialized Target Optimization
Our hearing devices feature patent pending Specialized Target Optimizationā„¢ (STO). STO is the worldā€™s first hearing technology that isolates and enhances the exact frequencies needed to improve hearing for your specific hunting environment. With STO, voices are clear, calling sounds natural, and the sounds of the game you are pursuing are all easily audible.

Tetra Wings Shooter

4 Pursuit-based programs in one device

  • Waterfowl Boost
  • Waterfowl Magnum
  • 1 Upland Boost
  • 1 Clay Shooting

TETRA products instantly shut down and instantly recover for sudden loud noises, like gunshots, providing the wearer full protection at the very moment itā€™s needed. For more sustained loud inputs, like loud calling, AlphaShield Compressionā„¢ 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.

ClearCommā„¢  is our proprietary algorithm that accentuates human speech while minimizing noises and distractions that occur outside of the frequency range of human voices. ClearComm is useful for better understanding speech and whispers of hunting partners, hearing speech on the range, as well as in other daily activities that require better hearing.

Hearing and the Brain

Research at Johns Hopkins University suggests that more hearing loss increases the risk of dementia. In one study, people with hearing loss were 24% more likely to have Alzheimerā€™s.* 

With hearing loss, our brains have to work much harder to make sense of what is being said, and even harder to filter out speech from unwanted background noise. Simply trying to understand conversations requires more mental energy and concentration. 

If basic conversations take up most of our mental energy, there is less opportunity for our brains to sort out and store other information. 

At TETRA, our goal is to minimize hearing loss for hunters and shooters, because research shows if we reduce hearing loss, we can also reduce the chance of getting dementia and Alzheimerā€™s.
