Hey Bone, I have the same camera too. I also was getting a few blanks, especially in low light. The motion sensor will detect movement out alot further than the flash will allow. I try to place my camera on a tree close to a natural barrier, brush pile, creek bank,etc....that way the deer have to come between the barrier and the camera. I also found that if I put my camera a little higher on the tree and angle it down, it keeps the detection range down, thus less blanks. Hope this helps.
