I'm interested in purchasing a scanner with the greatest frequency coverage
range possible and offering the widest selection of reception modes.

I would like to be able to monitor police, fire, air traffic, government and
other services. There are so many different makes and models it's hard to
know which are the best choices.

Price is not really an issue (although *very* expensive models are outside
my budget).

Will someone please offer me some advice or recommendations?

TIA

Samantha
