If you want to identify wires and blocking and don't have a camera that will do the job, you can buy packs of rare earth magnet discs, tape them to a strip of cardboard and staple the strip to the framing. Then, when you need to find them, you can use another magnet taped to a strip of paper or a string and wave it over the area where you think it is located. You'll know when you find them. You can wrap painter's tape on a strip of sheet metal, to locate them, too. Wave it in the area of the magnet.
