As far as handheld scanners go, stick with the name brands, Icom, Uniden, Radio Shack. I've had good
success with all three. Get the best you can afford. Not familiar with the two you mention to make an
observation.
You should also think about what frequency coverage you want and just what you want to hear. Only
air to ground transmissions? What about listening to ground airport maintenance vehicles, emergency
vehicles, etc. on the FM LOW/VHF/UHF Band? Are there military aircraft using the airport? Want to listen
to them?
Then you may need to add 225-400 Mhz AM military air as well as 138 to 144 Mhz FM.
Often folks start out listening to just one band, but find that other frequency bands cover activity related to
their band of interest. Your choice. But with a full coverage scanner you have it all at your fingertips.
You can also go to the RadioReference web site. They have a section in their Forum devoted to aviation
listening with numerous tips for new listeners.
