PolyCarbonate Goose Calls made from PolyCarbonate, which is a hard bulletproof plastic material. These Calls will last for years to come. They don’t have quite the range of our acrylic goose calls, but they can still get loud and are extremely easy to blow. Our gut system in our goose calls makes for a comfortable air pressure change in an instant. By turning and pushing the guts in slowly or pulling them out, you can make your call harder or easier to blow depending on your air pressure. We have made achieving loud volume affordable!
