The new Mini Marsh is a combination of thousands of hours learning to make a world class sound and the last 13 years of actual trial and use in the duck blind. To compete with the best, you have to become the best. We belive we have developed the best all around single (and double reed upon request) call available to convince the 2025 mallard to come to you! Guaranteed to work in all weather conditions with our state of the art spit channel system. Lifetime guarantee!
