Fire scanners can be bought at a number of online locations like Radio Shack. Most fire scanners are referred to as either police and fire scanners, or police, fire and emergency medical services scanners. Sometimes, they are simply referred to as scanners.
The scanners come either preprogrammed or can purchase them with the ability to be programmed to pick up specific scan ranges. The preprogrammed scanners are able to simply be turned on and immediately pick up the local channels. Many scanners have GPS options for people that travel. This gives travelers the option to pick up the channels for the area that a traveler is in making it easier to pick up fire and police reports.
