equicoach instruction set with talk-back function

The instructional system that allows talking back and forth without pressing a button.

The equicoach instruction system is a system where "back and forth" communication between rider and instructor is possible.
So the instructor can talk to the rider without pressing a button and this is also possible the other way around.
The equicoach does not work with bluetooth like other systems, we have deliberately chosen this to have a good range in all circumstances.
Range of the equicoach is at least 250 meters in practice, with most other systems the range is specified under laboratory conditions.
