Anyone have opinions on these two scanners? I like my 500 ten times better. First is the digital audio quality is way better plus the battery life of the 668 is horrible.[/QUOTE
Considering it's compact size, the PRO-668 does a respectable job. Personally back when I had both, I liked the PRO-500 because it was easier to handle with my large hands, and the display was easier to read. But I really had no complaints with the 668. Like most scanners, it boils down to a few unique features, and your personal preference. Sometimes that all it is, is personal preference.
