Multi-Pursuit CustomShield $2,499.00 / Pair
CustomShield orders require ear impressions. Any associated costs are the responsibility of the customer. After placing your order, you will receive an email from TETRA customer service with instructions and help finding a local professional.

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.

No what I expected

My ears started to get sore after wearing for a couple hours. A softer plastic would be better. The sound programming filters too much ambient sound.

Not As Expected - Trying To Return Them

On September 14, 2023 I received my new Multi-Pursuit Custom Shields and was really impressed on how well they fit my ears and blocked out sound. However, once I turned them on that is where my positive experience stopped. What I found was that the sound in both ears was really trebly and there was very little low end or bass. I tried the various different settings (deer, elk, waterfall, etc) but here was no difference. I also found that I could not hear noises very well that were on the other side of the room but noises within about 10-15 feet were very loud and again very trebly. The next day I left for an archery Elk hunt and took the custom shield with me to give them a try in the field. What I found was the same issues as in my house to the point I could not even use them to hunt. I could not hear anything far away and when I turned then up to try to hear Elk that were bugling not far from me, I could not move because any sound within 10-15 feet of me washed out those bugles. Sounds like a zipper, my clothes brushing up against bushes or the crunching of my boots on the ground as a walked was all I could hear. I had only had the Custom Shield for one week when I emailed them stating I would like to work with them to make adjustments to my customs shields. After a week with no response I emailed them again asking to just return them under the 30 day return policy. However, I have gotten no response back from either email. Not a positive experience so far.

Did not work for me

I first received the Multi-Pursuit Custom Shield. I had to return them because 2 of my programs were not programed. I had 2 non requested programs. After receiving them back with the correct programs. I tried them for 6 days. They were muffled on sounds. The Clear Comm program I had difficulty hearing conversations or watching tv. I can hear better without them. I did like the elimination of loud sounds. Compared to my Action Ears Scout, the Scout is far superior. I returned them for a refund. I received a refund approximately a week later. Overall I was disappointed with them.

Not So Good

When I got the instruments the outside was the wrong color (black instead of beige) and the programs "jumped" with outside noise. Clearly defective. Customer support agreed, promptly sent me a return, prepaid label. I returned the instruments 2 weeks ago and haven't heard back from TETRA. So, I can't tell you how well, or not so well, they work. Thus, the jury is currently undecided.

Great product

These hearing aid were one of the best purchases of hunting/everyday gear I've ever bought. I use it every day while at work. While I haven't got around to hunting in them so far I've used them at the range and it's amazing how well you can converse with friends and still protect your hearing. The custom shields were a little harder to get fitted and tuned but it is worth it. I'm 38 and Doc says I'm already experiencing slight hearing loss. These actually help my hear and protect it authentic same time. I got bluetooth capable ear protection also and it comes in handy although I could've opted out of that as these are mostly used when I need to be very aware of my surroundings. If you're ready for good hearing protection with the capability of hearing your surroundings which in most cases makes you safer quit looking and buy these. It's expensive? Yes. But I'm telling you it's more than worth it in so many way!
