Spend the extra money on a no flash camera if you look at most pics of deer with a flash camera they are spooked by the flash some my stick around for another pic but your mature bucks will not. you may get a great pic a a mature buck but that is probably the only pic you will get of him...a flash in the dark in the woods is not a natural thing for deer to see the big bucks will avoid that area of the camera. besides why take the chance of spooking a monster from the area you want to hunt. there are some great no flash cameras on the market right now for under 200 dollars like the new Remington ghost and the Moultrie I-40..
Good luck this fall and shoot straight.
