OK, seriously.
I don't put much faith in any kind of bottled scent. That goes for in the rut as well as out of it. The deer seem to either get nervous when they smell it or just ignore it completely. I'd stay away from that stuff.
As far as calls, I use a fawn bleat as a curiosity inducer. It's out of place in the late fall but it does seem to make deer look around for the source. I only use it when I can see the deer and want to stop them or maybe get them to mill around a bit. As far as a call that will draw unseen deer or elk in outside the rut, I have no clue.
