The metal detector is an item used to scan for metallic objects. It was used by Carla as part of her job as a security guard. Manny acquires the metal detector by sampling some Golden Flake Liqueur, which sets off the alarm, and then frustrating Carla, causing her to throw the metal detector into the racing cat litterbox outside her window. Manny retrieves the metal detector by using his metallic scythe to locate and hoist it up. He then gives it to Membrillo the coroner to assist in his searching of sprouted souls.
