Your guests can interact with you and each other and ask questions, not just listen to your presentation.

 

They can simply push a button to ask a question, a bit like a walkie-talkie, and everyone can hear them. 

 

The transmitter also has an Aux connection so you can connect a phone or mp3 player for some background music during the tour OR simply play a pre recorded tour commentary or message instead of speaking. Up to 3 simultaneous tour groups can operate in the same 10x10mtr area at once without causing audible interference. If they are more than 10 metres apart you can run more at the same time.
