The Albrecht ATT 100 is a tourist transceiver with an extremely small size and sturdy construction. It has 20 speech channels with which you can reach the visitor up to 2 km. Also, depending on the selected transmission power, the battery lasts a whole day (with continuous transmission for up to 6 hours with one battery). Finally, using the GHS01 headset not only lets you stream your own announcements, but also stream music or pre-recorded content from MP3 players.
