I'm sure you know this, but the only thing Mojos are working on are divers.
They're already skiddish of anything spinning, unless you are hunting a fresh cut cornfield.
Old-fashioned jerk cords with Canada butts work for the puddlers.
Watch your flocks of geese, alot of Mallards/Pintails flying with them.
Feeding chuckles,with a very limited highballs work.
Everyone here thinks that they have to knock them down with sound waves.
A little is more..
