Passage: Batman keeps most of his field equipment in his utility belt. Over the years it has shown to contain an assortment of crime-fighting tools, weapons, and investigative and technological instruments. Different versions of the belt have these items stored in compartments, often as pouches or hard cylinders attached evenly around it. Batman is often depicted as carrying a projectile which shoots a retractable grappling hook attached to a cable. This allows him to attach to distant objects, be propelled into the air, and thus swing from the rooftops of Gotham City. An exception to the range of Batman's equipment are guns, which he refuses to use on principle, since a gun was used in his parents' murder.
