one advantage it gives i just found out, is that you can mount it on even a small tree. something so small you'd need to wedge sticks in if you were using a strap. I just set up one of my cams with a ball and socket mount on a tree that's only 2" in diameter. That mount came with this particular camera, and I never used it, because it was designed for flat surfaces. I found I could get two of the three screws on the plate in that little tree, and it was quite sufficient to hold the camera steady. The mice had half chewed through the strap on this camera, so I was glad to mount it solidly.
