Cuddeback is the fastest trip time of all the trail cameras out today so far. But the Moultrie is the second fastest. I use the moultrie 1.3 and not used the 3.1 yet but I would set up on a trail facing north or south and facing straight up the trail of the deer coming into the camera. Setting up east or west will fool the camera into tripping fausely with the rising or setting sun. Also, if you can't bait, put out a scent dripper about 20 feet in front of the camera. That may help stop a buck for a moment. Good luck.
