I just bought the Pro 73, the first time I have ever used a detector. I drove the 395 in California, up to Bishop, and the alarms drove me nuts.
There were clearly dozens of false alarms, on wide open freeway surrounded by open land. I even got a maximum strength signal(ka I think) for a few miles, and other alarms were clearly from other cars or trucks. I saw no cops nearby, and people who were travelling faster didn't get stopped.
Will the Escort 8500 take care of the high number of alarms?
