6 Best Scaup Calls for Open Water Hunting

The wind is howling across the bay, turning the gray water into a sea of whitecaps. Far out, a string of bluebills banks hard, flying low over the waves. You raise your call to your lips, but the sound of your trusty mallard call is swallowed by the gale before it travels ten feet. This is big water diver hunting, and it demands a completely different set of tools and techniques.

Why Standard Mallard Calls Won’t Work for Scaup

Hunting scaup, or bluebills, on open water is a different game than calling mallards into a quiet marsh. Mallards communicate with a series of distinct quacks, which is what most standard duck calls are designed to replicate. Scaup, on the other hand, make a guttural, rolling purr or a raspy growl—a sound that a mallard call simply cannot produce.

The environment itself presents the biggest challenge. The sound needs to carry over the constant noise of wind and crashing waves. A mallard call’s higher-pitched quack gets shredded and dissipated by the wind. A scaup call is built to produce a lower-frequency, guttural sound that has the power and tone to punch through that ambient noise and reach distant flocks. Using the wrong call isn’t just ineffective; it sounds completely unnatural and can flare birds that might have otherwise decoyed.

Haydel’s DR-85: The Classic Call for Loud Purrs

When you just need to be heard over a stiff north wind, the Haydel’s DR-85 Diver is a classic for a reason. This call isn’t about subtle finesse; it’s about raw, penetrating volume. It’s designed to be blown hard, producing a loud, rolling purr that effectively mimics a raft of contented scaup.

For the weekend warrior or the hunter building their first diver-specific lanyard, the DR-85 is an excellent starting point. It’s affordable, incredibly durable, and easy to use right out of the package. Its main purpose is to get the attention of birds at a distance. The tradeoff is that it may lack the raspy, finishing detail of more expensive custom calls, but when birds are far out on the chop, getting their attention is the only thing that matters.

Buck Gardner Bluebill for Authentic Scaup Sounds

If your goal is to perfectly replicate the unique growl of a greater scaup, the Buck Gardner Bluebill call is a fantastic choice. This call is engineered specifically for realism. It produces a deep, throaty purr with the distinct guttural rattle that is characteristic of bluebills, making it deadly on days when birds are circling and seem hesitant.

This call shines when you need to sound like an actual duck, not just a loud noise. It’s a great tool for finishing birds that have already turned your way or for hunting on slightly calmer days where the subtleties of a call can be heard. It may require a bit more breath control to master its full range, but the payoff is a level of authenticity that can convince even the wariest late-season divers.

RNT Quackhead Diver: A Raspy Big Water Performer

Imagine a day where the wind isn’t just blowing, it’s cutting. For those conditions, you need a call with a raspy edge that slices through the noise, and the RNT Quackhead Diver delivers exactly that. RNT is known for its "meaty" sounding calls, and this one brings a heavy, gravelly rasp to the diver world.

This call is a true big water performer, built for hunters who consistently face challenging conditions. The rasp adds a layer of realism and helps the sound carry without being piercingly high-pitched. This is a great option for the hunter looking to upgrade from a basic model to something with more character and top-end power. It has the volume to reach out and the authentic sound to finish birds up close.

Zink Power Hen PH-1 Diver for Cutting Through Wind

Fred Zink’s "Power Hen" line is legendary for its sheer volume and ability to perform under pressure, and the PH-1 Diver is no exception. This call is purpose-built to be leaned on hard in the worst weather. If you hunt vast, open bodies of water where flocks can be a half-mile away, this call has the horsepower to get their attention.

The design of the Zink PH-1 allows a hunter to put a tremendous amount of air into it without the reed locking up or squealing—a common failure point in lesser calls. It’s a tool for aggressive, long-distance calling. While it can produce softer purrs for close-in work, its primary strength is its ability to project a loud, clear sound across windy expanses, making it a top choice for layout boat hunters and shoreline setups on major lakes and coastal bays.

Primos High Roller: Versatility for Divers & Puddlers

For the hunter who pursues a little bit of everything, a lanyard full of single-purpose calls can be cumbersome and expensive. The Primos High Roller offers a unique solution. With its innovative roller design, it can produce the purrs of scaup and redheads, the whistle of a pintail, and the quack of a wigeon, all in one package.

This call is the ultimate generalist. It’s the perfect choice for the hunter who might be targeting divers in the morning and puddle ducks in the evening. The tradeoff for this versatility is that it may not produce the single most authentic scaup sound compared to a dedicated bluebill call. However, for its price and multi-species capability, it provides incredible value and is a fantastic tool for simplifying your gear.

JJ Lares Diver: A Premium Call for Serious Hunters

When calling becomes an art form and you demand the absolute best in performance and craftsmanship, you arrive at calls like the JJ Lares Diver. Often crafted from high-quality acrylic, these are finely tuned instruments. They are known for their responsiveness, tonal range, and the rich, complex sounds they can produce with minimal effort.

A premium call like a Lares isn’t just about being loud; it’s about control. It allows a skilled caller to produce a wide spectrum of sounds, from soft, contented purrs to loud, aggressive growls, all with subtle changes in air pressure. This is an investment for the serious waterfowler who understands the nuances of calling and wants a tool that can match their skill. The cost is significant, but for those who live for diver hunting, the performance and consistency are worth it.

Calling Techniques for Windy, Open Water Conditions

Having the right call is only half the battle; using it effectively in tough conditions is what fills the strap. The wind and waves are your competition, so your technique needs to be adapted to overcome them.

First, focus on volume and cadence. You need to be louder and more aggressive than you would be in a sheltered marsh. Use short, powerful bursts of rolling purrs to cut through the wind. Think of it as shouting to be heard in a crowded room. A continuous, long purr will get lost; sharp, rhythmic sounds are more likely to catch a duck’s ear.

Second, let the birds’ behavior guide your calling. Watch their wingbeats and direction. If a distant flock turns its head or slightly alters its course after a call, you have their attention—now is the time to coax them in with softer, more contented purrs. If they continue flying away, hit them with another loud, attention-grabbing series of growls. Calling is a conversation, not a monologue. Always be reacting to what the ducks are doing.

Finally, use the conditions to your advantage. Sound travels with the wind. If you can, position your blind or boat so the wind is carrying your calls toward the areas where you expect to see birds. And most importantly, call with confidence. A timid, uncertain call sounds unnatural. Even if your technique isn’t perfect, a loud, confident, and rhythmic purr is far more effective than a weak, hesitant attempt.

Ultimately, the best scaup call is the one you have on your lanyard on a cold, choppy morning. Don’t get paralyzed by gear choices. Pick a call that fits your budget and the conditions you hunt most often, practice with it, and get out there. The real magic happens on the water, not in a catalog.
