I'm new to scanners and am not clear on some of the terms used, so please excuse my basic questions.
I'm looking for a very, very inexpensive scanner for use at home (either a base or a hand-held with a power adapter) to listen to Escondido-area fire and police.
So here's some of my questions:
1) From what I've read on ScanDiego.com, I will need a digital, trunking scanner. Is this correct?
2) What scanner would you recommend? Keep in mind that I'm on a very limited budget and I don't need any bells and whistles....just something that works. Used is best for me since I'd probably save a bunch.
3) I've seen digital trunking, dual trunking, and triple trunking. What does this mean and what does it have to do with elephants?

Thanks!
