I'm getting my son a new handheld scanner for his birthday (December 24) and Christmas. Since he's only getting the one gift; I want it to be nice. He wants to listen to taxis and drive thru windows for whatever strange reason. Kids lol! He's not even remotely interested in what Metro or the fire department is doing. So...does he need a digital trunking type scanner or will analog do? Will he be able to listen to the dispatchers and cashiers with analog or should I shove out the $500 for a digital? Any suggestions on brands or accessories that he'll need? I have no idea about how these work, I just know that I don't want end up sending it back. Thanks for reading.
