Unlike some of the more world-saving Avengers, Spider-Man is usually more focused on the smaller everyday threats around New York City. Because of these street-level heroics, the Iron-Spider’s built-in emergency scanner would very much come in handy.
The scanner allows Spidey to listen in on police, fire and ambulance radio frequencies
to alert him to the latest emergencies around the city. The scanner doesn’t seem as practical for his Infinity War adventures as he leaves his big city crime-fighting to take on more intergalactic threats.
