I noted that many of you mention that you have different things programmed in to the various scanners, and listen to different things on each scanner.
I listen to different things on each scanner, but I program each scanner type identically. By "type", I mean all of my modern Unidens have the same profile, and all of my modern Whistlers have the same profile. I use the bank/zone selection to determine what each scanner actually monitors. This allows me to only have to edit a single profile per scanner type, and then I can load the one profile into all of the scanners of that type. And if (when) I get another of the same scanner type, it's ready to use in just a couple minutes. Having all of the scanners programmed identically also makes finding things quick and easy when time matters. Modern scanners have enough memory capacity to load in "everything".
