RE: Good Call Question
One of the best mallard calls you can get is Haydel's DR-85. It is very inexpensive, but any truthful call manufacturer will tell you it has put more ducks on the water than any other call. I use it all the time. You can get it for under $20.
With expensive calls - you are paying for expensive plastics, a metal band, and someone's name attached to it. That does niot mean it sounds more realistic, or is better.
