Two-way, wireless tour guide system, 2.4 GHz. Allows two or more tour guides to combine skills and guide as a team to a group. Enhances communication between tour guide and tour group members. One- and two-way simultaneous communication is available: two tour guides can speak simultaneously; group members can hear both tour guides; group can participate as listen-only or can access 2-way mode with the quick push of a button. Two-way capability allows for group Q&A. Tour guides always control the discussion.
