When learning to call make sure you call sparingly. Often a only a quack or two is far better than the hail call everyone and their brother is blowing. Also, you will kill more ducks by getting movement in your spread than you will with a duck call. Get a spinner and a jerk string setup for the calm days. Most importantly, figure out where birds are landing and put your decoys there. Being where the birds want to go is infinitely more important that what decoys you use, what you put out, what calls you blow, etc. If you put your spread where the birds want to be you will tons of birds.
