(Idea from Don Meredith)
Grab yourself an elastic and connect it to the camera via where a cord attaches. Then just stab your pole into the ground and connect the camera to the handle by stretching the elastic around the handle and over the far side of the camera.
If this doesn't make sense, check out Don's video here:
This method works great and it's lighter, simple and quicker than screwing the camera on. I actually use some thin shockcord instead of an elastic band so it's a bit more robust, but an elastic is fine.
