The overall impact of Rover is having better information at your fingertips without having to ask. The graphic position of hydrants on a map by the alarm location has been a huge help to responding engines. The days of having to memorize that information or laying in from a bad location are gone.
I depend on Rover to let me know who is coming to the station so I know my staffing before leaving the station—there is nothing worse than leaving the station by yourself or with a minimum crew, wishing you had a better crew on board and then finding out when you get back to the station that others arrived after you departed to the scene. Rover provides me with a digital view of the dispatch and who is responding from my department as well as from mutual aid departments.
