How much warning time does a K40 radar detector provide?
A. Trying to estimate warning time in an actual mile or feet measurement is impossible because true warning time is influenced by many outside variables that have nothing to do with the radar detector itself. For example, the strength of the radar signal being transmitted, the direction the gun is pointed, the length of time it is transmitting, the positioning of the patrol car, and the influence of other objects around you may all affect how your radar detector receives a signal.
