Swivel Shooting Plateform

I’ve been hunting coyote at night lately and the place I hunt is about 120 yards deep ( away) and about 45 yards wide. I’m constantly scanning left and right looking and with a bipod I have to move my body left and right constantly. Pain.. Did some thinking and came up with this. The rear is a 5/16" bolt ground to a point. The front is two used swivel casters I harvested off a clothes stand. I haven’t hunted with it yet but in shop tests, it seems very promising.
