Echo Calls 77764 Open Water Single Reed Mallard Hen Duck Call

The Echo Calls 77764 Open Water delivers authentic mallard hen vocalizations that consistently draw ducks within shooting range. This single reed call produces the full spectrum of hen sounds from soft feeding chuckles to aggressive comeback calls. Constructed from durable dark green acrylic, it withstands harsh wetland conditions while maintaining tonal clarity.

What Makes This Different

The Open Water features Echo's precision-tuned single reed system that requires minimal air pressure for maximum volume output. Unlike multi-reed calls that can stick in cold weather, this single reed design maintains consistent performance in freezing temperatures. The acrylic construction eliminates wood swelling issues common with traditional calls, ensuring reliable operation throughout the season.
