Most people don't realize that using a call for Canvasbacks can be as productive as using one for Mallards. You can buy a Diver call or use a raspy mallard call, roll your tongue into the call BRRRRRrrrrrrrrrrrr, Brrrrrrrrrrrrrrrrrrr. Don't be afraid to change it up a bit with some soft raspy quacks with a few squelches.
20-35 yards is perfect distance for pulling the trigger. 1 1/8 oz. 2 shot is sufficient for most people ,but use what you are comfortable shooting.
