Wound up buying a Wildlife Innovations S2 with the flash from Sportsman's Guide. Was going to step up to the IR4 model, but the S2 was faster by nearly a second, so I stayed with it. My brother uses a Moultrie D4 and also tells me the flash doesn't scare deer. The only thing I would have liked about the IR flashless model is for use on two-legged coyotes if you know what I mean.
Maybe like this guy? You may know him
I know I do, and he is not on his property.
