Lower right corner seems available on the LCD.
Dunno about everyone else who has a 500 or 600 series scanner but *my* `lower right corner' is quite well used / occupied and even with it being able to shift back a forth between what is displayed there I really cannot see display a `hit counter' `count' `realtime'.
As for the `hit counter' itself... Again personally... I seldom use it and when I do it is usually just when I'm figuring out either a totally new system or checking out a possible new TG in an exisitng system or new freq that I happened to have `stumbled upon' via one of my other scanners. Checking the count using the software on my computer is more than adequate to provide a `Yea' or `Nay' determination *for me* in those instances.
Just an `Olde Fart's' 2¢ worth. {GRIN!}
