I thought maybe that was exactly what it was and then thought, you got to be kidding me...LOL Now I've seen it all. Interesting, I could imagine them being necessary in a wet enviroment, I just never saw one before.
You'd be surprised how handy they really are. Keeps the cam from getting beat up when you prop your bow against a tree, or your stool or whatever. Don't have to worry about mud, gravel, or anything else.
