monitor 5

so I have the G5 radio that i use a just a scanner. I'm wondering if there is a way while listening to something as to mark it so that it would be easy to find in the message box?

Hey, I volunteer with a fire dept. And as you know, our pagers get damaged and lost very easy due to the job. Well turns out I've lost/broke to many, and now no longer have one. Can anyone tell me a good alternative scanner/pager that won't break the bank. The scanner could be a desk top one...
