Duck whistles are very effective for adding realism to your calling and for getting call-shy or working birds to commit. They're greatly under-utilized by waterfowlers, which makes them even more effective for hunters that use them. When it is late in the season and the ducks have heard everyone north of them hail calling at the top of their lungs, the soft "dreeet" of a mallard drake grunt will get them to commit when they otherwise might not.
My whistles are the perfect gift for the waterfowler that has everything. He or she may have hundreds of dollars worth of calls on their lanyard, but they probably don't have a custom duck whistle. Odds are, they have a $12 molded plastic one. Those work fine, but they don't have the fine craftsmanship that the other calls on that lanyard probably do.
There's nothing to tune with these. No parts to lose or replace periodically. They are incredibly easy to use, and just take a whisper of air. They're an excellent way to let a kid (or a friend that can't call worth a darn) get involved in calling during the hunt, as opposed to just deferring to a more experienced caller. Experienced callers know that adding realism in a calling cadence can turn birds, and a whistle can do just that.
Beware of imitations of my design that have hit the market recently. I'm not talking about other craftsmen that make whistles, many of which I consider friends, I'm talking about blatant copies and those whistles that are eerily similar looking. Although I can't speak to their sound or build quality, someone that blatantly copies a well-established unique call design lacks the integrity or soul of a craftsman that should drive them to create their own unique design. I'm not the first to make a two hole duck whistle and I'm not the only option out there, but a couple of my design's features are very unique and easily recognizable, and a couple features that are uniquely mine are more subtle. A couple of these people are quick to post on social media and the internet forums when someone inquires about my calls, in an effort to sell their own. That is something I would never consider doing to them, but that's just me. Let your conscience guide you on that matter. Look closely at the build quality of the whistle you're considering that looks a heck of a lot like what I build and see if it matches up to a Wingert whistle. Odds are, it doesn't. Own the original, not the imitation.
The following pictures illustrate many of the materials that I offer, but in no way are intended to represent EVERY material I have. I have hundreds of blanks, dozens and dozens of different woods, and numerous types of other material as well. Some blanks are totally unique and my inventory varies. Rest assured that when it is your turn to have your call built, you'll have a ton of materials to choose from. If you'd rather I choose, give me a little direction and I'll make the hard choices.
