I've had one for years, still works like new, unfortunatly most radio is on 700mhz digital now around here. The BCT 7 has an alarm light and tone for highway patrol alerts so it is designed for mobile use. Mine is in the house now and I use it for mostly searching, not scanning anymore. When I used it mobile it was an excellent unit, the constant alarms can be a bother at times. It's preprogrammed by state so when you cross the line, just dial up the new state and your all set. I still take it on trips for that reason, but use a 396T now when I am in the county.
