Polycarbonate is essentially bulletproof plastic, similar to Plexiglas. Its dense composition gives it excellent acoustic qualities with a softer sound than the Acrylic, it is highly durable so very unlikely to crack when dropped, and it is affordable for both manufacturers and hunters.

Double reed calls are user-friendly and produce accurate duck vocalizations with more forgiveness when it comes to air control and mechanics. This makes double reed calls an ideal choice for hunters of all skill levels because they are easy to learn with, as well as being reliable for experienced callers. Double reeds sacrifice a little bit of volume and don't have the full range of tone like a single reed.

Pro Tip:
Duck hunters benefit from using both single and double reed calls. Different hen mallards have different tones, so being able to vary the sound of your calling will play to your advantage - especially on pressured ducks.

The Spit-Tech technology is exclusive to BG calls. It enables the call to blow when wet from spit, condensation, and even accidental dips in the water. This technology is achieved through skillful hand tuning, custom fitting, and the testing of each call.

Short Barrel Technology - Simply put the SBT series allow callers at any level of expertise to blow the full range needed to bring ducks within range. It offers waterfowlers an easily controlled call without sacrificing any of the sound qualities that you'll need in a variety of hunting situations. Soft quacks, feed calling, come-backs, and hail calls are easily accomplished. The smaller air cavity provides improved caller control with less air, but still delivers plenty of boldness.
