The WHIS Contest has a fully protected private connection. This 'private connection' technology ensures that in a setting where many instruction sets are used, WHIS Competition fully automatically regulates that the instructor maintains his or her private connection with the rider. The WHIS competition offers the instructor and rider the opportunity to communicate with each other (conversing with the instructor). The supplied headphones specially designed for cyclists sit hygienically next to the ear. WHIS Competition has the shortest connection time, without echo or reverberation. Because the talkback function is not always necessary or desired, you can also choose to use only the listen function with WHIS Competition using the different types of headphones supplied. WHIS Competition is very easy to use, all you have to do is turn on the device. In practice, the range of WHIS Competition is guaranteed up to 100 meters, which is more than enough for a dressage arena. The illuminated display in a unique design shows battery status, connectivity and volume, which is useful because you always know where you are. The WHIS Competition is equipped with a replaceable battery and a charger with a global plug. In short, everything has been thought of.
