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-pending ™ (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 don’t, like loud gun shots. Now, with our gundog device, you can get custom programming in one convenient device, and changing between programs is as easy as one simple tap.

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