Finally retired and I am going to "bite the bullet" and get a new scanner. I have kids that live from Idaho to Arkansas, to Kentucky, to North Carolina. I need a scanner that uses a SD card, digital, portable with dc/ac backup power, and rugged! I know that there are several models available, but I need the input of people that are using these models. My primary interest is fire/ems, parks/recreation. I don't want to have to reprogram the scanner every time I cross a state or county line. Any help is appreciated.
