That's the neat thing about the Duck Commander. It's low effort to blow, makes nice soft and throaty chuckles and quacks and is loud and raspy in a hail or come back call, all in one call. I only ever have two calls on me and I pick up the wrong call half the time, LOL! I got this new Drake waterproof pull over with zip open vents that has a call separator on it which helps a LOT! If I'm duck hunting I stick the goose call in that loop and if I'm goose hunting, I stick the duck call in that loop. It's a neat parka, can wear it over my field jacket or alone in warmer weather. My sweety got it for me for Christmas this year.
One thing, get a lone speck and he'll often come like a magnet, lookin' for friends. I've called 'em down without even any deeks if they're real lonely, when I'm out duck hunting, close enough to pop 'em with 3 steel in 2 3/4" fasteel loads. Late season snows are a challenge unless you're just in the right feeding area and it's where they wanna be.
They get mighty wise late season and can just hang up there at 50 yards or a little more sticking their tongues out at you. Takes a good load to bring 'em down from that range, bB steel in 3" 12 is anemic. Hevi shot or steel Ts from a 3.5" will hammer 'em and I get the last laugh.
Late season ducks can be real frustrating, too. Early season they call a lot easier. If you're on the right spot, though, you won't even need the call. I've found few of those "right spots", but I know about a few, little hard to get to, long boat ride, but I know where they are, duck hunter's heaven.
This one hole, hell, you don't need anything, decoys, anything. It's friggin' amazing. A couple of feeding chuckles and they zero in on you. I don't think Mexico or Argentina could be any better for ducks and this hole is only about 100 miles from me, 20 of that on the water, though.
