Echo Calls Canada acrylic goose calls are very popular among the Canada goose hunters. The acrylic call has great range for long distance calling, as well as close in sweet talking. Each acrylic call comes with a stainless steel band and the Echo logo laser engraved on the barrel. The guts have tuning posts at the back of the tone channel. This allows the hunter to adjust the call for soft, medium, or hard calling in seconds.
