RE: snowy day deer
Mine has excellent trigger speed under 1 second. The only problem with them is they go to sleep. By this I mean if there is no activity forI think it 3 minutes it goes to sleep once something is detected it activates itself again the next movement sets it off almost instantly. It is supposed to be a battery saving feature. I'm very happly with it I didn't want to spend $400 either. For the money I think there hard to beat.
