Hi Guys,
I'd like to throw a few words into the ring If I may to clear a few things up.
Radio helmets are not good lessons, they are only a tool at the disposal of the instructors to improve the lesson quality if the instructor feels it works for them. In our school, no instructor is forced to use the radios, they can choose to simply not turn the units on. All instructors do use the helmets with radios on.
Radio helmets are a really great communication tool to use when teaching students throughout the instruction process. The key word is that the helmets are a "tool" which enhance the quality of a good lesson. They are not a silver bullet for making bad instruction better. The radio comms are simply a conduit through which the advice is channeled.
Quality lessons are defined by the quality of instruction offered. Experienced instructors catch the small visual clues that other may miss, and use them to offer remedial instruction as it is needed, not after.
Every location has pro's and cons. It is the instructors job to modify their lesson style and content to take into account the difficulties on any location and make positives from them.
The ability to get timely advice across to the student in a calm collected voice is in my opinion, essential so we can try and avoid the situation where a hapless student is getting dragged out of control. I am under no delusions that this can't happen to a student in a radio helmet as well, but the ability to get information to the rider even if the students head is underwater is a great bonus.
I mean, if a student is going to wear a helmet in any case, what is the harm in having a communication device built in? Radio helmets are obviously not compulsory for use in schools and it is the schools decision to include their use or not.
AKS have used the helmets for the last 4 years throughout much of the testing and R & D stages of Headzone, with many ongoing problems and frustrations (mostly charging issues, not transmission problems), not to mention the enormous cost of the helmets and radios, and ongoing, time consuming, regular preventative maintenance (every day).
On top of all these problems, we believe they offer a real value and benefit to our coaches and our customers. So we continue to use them. Headzone have been good to deal with but if I didn't consider them an essential tool to our lesson plan, then I would have dumped them long ago.
Customers vote their confidence in the service they receive with their wallets, and will return for additional lessons if they are satisfied with the level of teaching in the first place. If both schools are busy and have plenty of customers, then this topic is nothing more than personal opinion of which each person is entitled.
Sorry this was a bit long winded but you get where I'm coming from right?

Cheers,
KH
