NOT SURE? TRY OUR Product Selector Tool

At TETRA, we used our patent-pending Specialized Target Optimization™ (STO) to isolate and enhance the exact frequencies hunters need to hear for a variety of pursuits: deer, elk, turkey, waterfowl, range, and upland. We took those frequencies and created custom programs to enhance the sounds you most need/want to hear - like duck calls, gobbles, and voices - and protect you from those you don’t. Now, with our multi-pursuit device, you can get all the custom programming in one convenient device. Changing between programs is as easy as one simple tap. Our CustomShield devices are custom molded for the most personalized fit possible

For years, manufacturers have expected hunters to take a “one-device-fits-all” approach to hearing protection. As hunters ourselves, we know that doesn’t work. The sounds we need to hear on the range or in a duck blind are completely different from those in the turkey woods or deer stand. No two hunts are alike, and your hearing protection shouldn’t be, either. Whether your passion is calling in mallards, flushing upland birds, smashing clay targets, running and gunning a big ‘ol tom, or waiting patiently for a trophy buck, TETRA is dedicated to protecting your hearing, while helping you “Hear The Hunt.”

TETRA isn’t just hearing protection, it’s hearing perfection.

Our Technology

Specialized Target Optimization
Our hearing devices feature patent pending Specialized Target Optimization™ (STO). STO is the world’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 CustomShield Multi-Pursuit

6 Pursuit-based programs in one device

  • Waterfowl Boost
  • Turkey Boost
  • Upland Boost
  • Deer Boost
  • Elk Boost
  • Clearcomm

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.

ClearComm™  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 Alzheimer’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 Alzheimer’s.

Good protection with fair sound quality

I've used my Multi-Pursuit Custom Shields in upland and waterfowl hunting situations for a few months now and I find them to be comfortable and easy to use. However; I find the sound quality between the booms to be "tinny". I've used both ESP and now Tetra and find the sound quality to be quite similar but the Tetra MPCS are clearly a better value given the lower price.

Do it!

I bought a pair for myself and one for my wife. We both love them. Being able to communicate in the blind and still be able to hear the birds AND protecting our hearing....is priceless. I was most worried about durability as we all know the abuse waterfowl gear is subjected to. I have dropped both my CustomShileds in the water at the blind, took them back to to the camp and let them dry on the windowsill, once the moisture was visibly gone, I put batteries back in them and they still worked! This was a year ago and they are still going strong with NO service required. I put a load of our hunting clothes thru the washer and dryer. When I pulled my wife's pants out of the dryer, I felt her CustomShields in the pocket. I just knew they were ruined. I changed the batteries out and they both still worked! This was 3 months ago and they still work the same as the day we got them. I recommend Tetra to all of my hunting buddies.

Montana goose hunt

Excellent! I could converse with my hunting partners and protected my ears from gun blast. Very positive!

Have only worn a few times. I like the sound clarity when speaking in normal tones. The volume control button is a bit small and I keep bumping the mode selection button while trying to adjust volume. Don't like having to pull batteries or leave door open while storing between uses. Going to Canada for grouse. Being able to detect beeper direction will be the ultimate test.

Over 200 Days Of Use In A Professional Setting

The most prevalent issue is the difference in sound quality between the left and right. The experience is so uncomfortable, I often have to use different program settings to achieve any sort of similarity between left and right. The next issue is the wind, they turn off completely in any breeze, these units do not cancel the wind. This leaves with you mid conversation with no hearing ability. The third and final complaint is when bent over, the units will shut off as well. Something as simple as looking down to grasp a duck call or whistle to handle a dog will cause the units to shut off. In these scenarios only one unit will shut off which can be very disorienting when in a sometimes chaotic and stressful environment such as hunting.
