The best equipment for my needs as a tour guide.
On the recommendation of another museum we purchased two TourVox portable PA systems to use while giving our museum tours. When addressing a large outdoor group we can easily turn up the volume for all to hear, and as we move into buildings, we can easily adjust the volume as to not overwhelm our visitors. Using the waist strap allows us to be hands free, which is essential. We are very pleased with our purchases and look forward to many more years of service from our TourVox.
