Suckers a duck magnet. It's a Y-shaped pole with two wind powered lucky ducks stuck on the ends.
A few years ago I was hunting in Kansas and could see some guys maybe 300 yards away using some type of contraption and ducks would pass us right up and file into their dekes. We asked them later on after they got their limits what they were using, and it was a Vortex.
A few weeks after that Garen (a buddy) bought one and we used it on some WMA's here in Arkansas last year before they got outlawed.
The sucker is magic. It brings ducks down from up high and right into gun range.
