Tetra is bringing more technology to the CustomShield series. The addition of BlueTooth expands an already outstanding range of hearing protection. It adds the ability to stream music and podcasts while making sure you're protected. Now, not only is my hearing protected but it's easier to coordinate with the other people in the field. 

At TETRA, we used our patent-pending Specialized Target Optimization™ (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.
