Choose 60-level if you have normal hearing and want high-end protection with standard enhancement. Choose 90-level if you have any degree of hearing loss, as these can be custom-programmed to your audiogram. The 90-level also features advanced wind-noise reduction and ClearComm™ technology for better voice clarity.

A Single Pursuit device is optimized for one specific environment (e.g., just Waterfowl). A Multi-Pursuit device allows you to toggle between different environments (e.g., Waterfowl, Turkey, and Range) within the same set of devices.

The Multi-Pursuit devices have the capacity for 6 of our STO programs, while the single pursuit devices are dedicated to only one program.

The NRR for AlphaShields is 20-21 dB, depending on the specific ear tip (silicone or foam) used and the quality of the fit.

CustomShields typically provide an NRR of 22-25 dB. Because they are molded exactly to your ear canal, they offer the most consistent and highest level of protection.

No. TETRA technology is specifically designed by audiologists who hunt. Our Specialized Target Optimization (STO) ensures that your calling sounds natural and is not "clipped" or distorted like standard electronic muffs.

AmpPods are primarily designed for maximum concealment and enhancement in the woods (like Turkey or Deer hunting). For high-volume shooting like Waterfowl or the Range, we recommend the Shield Series for better occlusion and protection.

The tech is the same, but the fit differs. AlphaShields are universal-fit (using tips), while CustomShields require an ear impression for a perfect, medical-grade fit. CustomShields are generally more comfortable for all-day wear.

Each STO program targets specific frequencies. For example, the Waterfowl program highlights the frequencies of ducks and geese while suppressing boat motors, while the Turkey program highlights the high-frequency "spit and drum."

The main differences are Fit (Universal vs. Custom) and Technology Level (60 vs. 90). You can compare all models and pursuits here.

Multi-Pursuit devices offer versatility. With the touch of a button, you can change the programming to match the game you are hunting that day, making one pair of devices useful for all seasons.

We do not include a lanyard because they often create "cord noise" that interferes with the microphones. However, we offer secure storage cases to keep them safe when not in use.

We offer an upgrade program. You can send back your universal devices and, for the price difference plus a custom lab fee, we can convert your technology into a custom-molded shell.

Most products just "turn down" loud noise. TETRA uses patent-pending technology to protect your ears while enhancing the specific sounds you need to hear for a successful hunt, based on your specific hearing profile.

You can, but it is not recommended. Turkey AmpPods are tuned for lower-volume environments. For the repeated, high-decibel reports of duck hunting, the Waterfowl Shield series is a safer choice for your hearing.

Our 90-level technology includes Advanced Wind Noise Management, which identifies and suppresses wind turbulence across the microphones while keeping the sounds of the hunt clear.

No, they are water-resistant. They can handle sweat and light rain, but they should never be submerged. If they get wet, remove the batteries and let them dry completely in a hearing aid dryer or with the battery door open.

Yes, provided you have a proper seal. For indoor ranges, which have much higher sound pressure levels, some users choose to "double up" with muffs over their AlphaShields for maximum safety.

Yes. AlphaShields are designed to provide impulse protection for all common hunting firearms, including high-caliber rifles.

Yes, they will protect your hearing. However, the Waterfowl optimization may not highlight the specific frequencies of a turkey or deer as effectively as the pursuit-specific programming would.

Most TETRA devices use Size 10 (Yellow tab) or Size 312 (Brown tab) zinc-air batteries, depending on the specific model.
