The Dutch Fire Academy hired Sennheiser 2020 Digital tour guide systems from us to help deliver their training programme. The tour guide system enabled the instructor to hear and monitor the two captains of each group from a distance. There were six simultaneous training groups.

This is an example without using the tour guide mic/receiver, where the instructor almost has to invade the one-to-one discussion between two captains to listen what they say.

As operational meetings on incident sites are already very crowded, it is very convenient for the instructors to be ‘out of the group’ while still being able to listen to what the fire chief or captain says. The two instructors are the top two (blue jackets).

From a distance the instructor gets a clear picture of what is happening and what effect the action of the commander has, while still hearing everything that is being said using the Sennheiser EK2020D tour guide receiver.
