I believe you forgot

camera: device that ensures no game will come near you. However effects can be disabled by simply it leaving in the car, using batteries with enough juice to turn it on- but then die, or not having enough space on your memory card to take new photos. In these scenarios effects are reversed and game is drawn towards you, with the stipulation you are either not on legal hunting grounds, or carrying a bow.

You know, I've been diligently taking my camera every single time I've hunted this year - that may just be why I am not seeing any deer.    

Bernie, you been in my shop??

I love that tool description.
