WHIS has been offering the solution for instructors and riders for many years now. Thanks to the WHIS wireless instruction systems, instructors can relay their instructions directly to their rider(s) without having to shout. The WHIS Competition and WHIS Original are the most well-known sets, but what are the differences and similarities?
Talk-back function for the rider
The WHIS Competition has both a listening-and a talk-back function. This is great for lessons with one or two riders. This allows ambitious riders to respond immediately to their instructor. The WHIS Original only has a listening function. That's perfect if the lesson contains a lot of riders who are all listening in on the instructor through their Original device. Imagine if in a lesson with a lot of riders, the Original devices had a talk-back function? Of course, that would make the lesson a lot more chaotic. That's why we recommend using the WHIS Original in lessons with more than two riders.
Instructing small or large groups of riders
The WHIS Original has great extension options. Up to twenty "Rider" devices can be connected to the "Instructor" device. Ideal if you are an instructor who teaches several riders at the same time. Choose the WHIS Competition if you are going to use the set for private lessons or lessons with up to two riders. This set is perfect for one-on-one contact between instructor and rider. 
The range of these WHIS sets
The WHIS Competition has a range of 100 metres. That is certainly sufficient for a dressage arena. The WHIS Original, on the other hand, has a longer range of no less than 280 metres.
What they have in common: Both easy to use
Both sets are extremely user-friendly and come with a manual so you can get started with your set right away. The Competition set automatically arranges that instructor and rider(s) can communicate privately with each other via the same channel as soon as you turn on the devices. Do you notice that there are users from another group communicating via the same channel? Then change the channel together with your fellow riders/instructor. There are more than enough channels, so you will always find a free channel. With the Original set, you follow two small steps for a perfect connection without noise. Make sure that the devices for Instructor and riders are on the same channel (right number on the screen) and that everyone sets the noise reduction correctly (left number on the screen).
In short: which set you choose depends entirely on the goal. For example, are you looking for a set for private lessons in dressage, jumping or eventing? Then choose the WHIS Competition. Are you looking for a set for more riders in one lesson? Then the WHIS Original is ideal because of the extension option.
