I've used a painted up McKenzie 3D target as a decoy. ( DOE)

We drilled a large hole in the rear ( No laughing ) and inserted a 35mm film canister. We filled the canister with cotton and some doe-in-heat scent.

When not in use, just snap on the lid.

My father and I have both taken bucks with this home made decoy.

That was years ago. It was too heavy and awkward getting in the woods.
