Well my guess is why you got blank pics is because of the brush in the lower left hand corner of the pics, if the wind was blowing the movement of that brush could have set it off, i also saw alot of leaves on the ground. In the pic where the 1st turkey is almost out of view, the size of the turkey and the height of the camera have alot to do with it. Note how on the pic where you and your friend or you and the girl walked past the pic snapped correctly.Thats just my opinion though. I have 2 scoutguards and when set up correctly i've had no problems.
