It drives me crazy when manufacturers give a generic name for a lure like "Coyote Special 500" and simply describe it as a great all season coyote lure. I want to know if a lure is a gland, curiosity, food, or call since I use them differently at different sets.
In all do respect how can u use a curiosity lure different than a call lure when u don't know the difference between them.
Call lures are lures that appeal to a variety of impulses of an animal. A call lure might have skunk, but not all skunky lures are call lures.
Curiousity lure is just something that your target isn't the familiar with.
Honestly I bet a bunch of formulations that fall under any category you want to put them have ingredients that your target animal isn't familiar with. And I bet a lot of the time those are the ingredients that give it the most attraction. Even a lot of gland lure are doctored with some pretty exotic ingredients.
