Digital GroupGuide™

The Digital GroupGuide™ (DGG™) is a highly successful, lightweight and easy-to-operate group-guiding system that provides digital clarity to up to 64 groups on discrete channels at the same time, over a range of up to 50 metres. It helps preserve a guide’s voice during the course of a tour, and allows them to conduct larger tours more frequently; and increases visitor satisfaction by providing greater autonomy and crystal clear commentary, even in the noisiest of settings.
