A 2.5" by 3.5" pad soaked in fresh Whitetail Doe in Estrus - then freeze dried. This power packed pad is sealed for years of freshness in a mylar bag. As moisture in the air reactivates the freeze dried powder, The Game Changer comes back to life and pulls bucks in. 
 
Once the seal is broken, you can hang it by the hole punch over a mock scrape or pull it in behind you on the way to the stand as a drag rag. 
 
One customer story, 'I hung the Game Changer above a mock scrape in early October & had multiple bucks show up on the camera - including the biggest deer on the property. Hooked for good.'
