"A good setup and location near a food source, along with smart decoy selection and placement, are the basis of effective diver hunting," says Lensing, though he won't hesitate to use a call when needed. "My go-to call is actually a mallard call," he says with a laugh. "When a circling flock of divers decides to boogie, I will make a real racket to try and get their attention and turn them. The sound I make is a real fast, choppy, and high-pitched comeback call. It works often enough that it's worth the effort."
