These scanners are for monitoiring the airbands. They do not transmit. We have a basic Maycom model which is ideal for listening at the local airport or on that overseas trip. This is a great model for students to build their radio skills with. We have several large schools using these for this exact purpoe.
We also offer a top of the line Icom unit which has a lot larger range and a larger selection of frequencies to choose from. If you would like to listen to the emergency services as well as the local radio/TV channels then this is the model for you.
