Best system is V1 with the Uniden Beartracker BCT-7 or BCT-10. It's a scanner that also searches for the state's specific "mobile extender" frequencies used by police and highway patrol. Based on signal strength of these low wattage communications relay radios (roughly proportional to distance away), the Beartracker will provide an audible and visual alert.

Here's how it works. Each squad car has a secondary radio whose function is to relay communications from the main car radio to the patrolman's walkie talkie. The Bearcat searches for these transmissions. Even if the patrolman turns off the walkie talkie while in the car (most do) they hardly ever turn off the mobile extender transmission (they might forget to turn it back on when egressing the vehicle in a hurry).

Real life example: Geographic bachelor commuting on the weekend from Newport RI to Virginia Beach transits, at a decent rate of speed, the NJ Turnpike. Bearcat Alerts and locks on a NJ State Trooper going north calling for another unit to pick up a south bound flyer. Other units respond, with their mile marker, and as I approach, at less than said decent rate of speed, I cruise on by, unmolested. The radar never went off, I assume they were using instant on and could clearly see that I was not the mark.

This system also works for aircraft traps since it scans VHF aircraft frequencies as well as the aforementioned mobile extenders.

I swear by the combination. It fits my psyche as former electronic warfare bubba.
