Do they make an item that allows two riders to communicate via a headset in the helmet? I know that they used to offer one for motorcycle riders and passengers. Anyone have any idea or has anyone rigged up something that achieves the same purpose?
Thanks!

I use this system and I'm happy with it. We run 3-4 atvs in a group all the time and it works well. It's sort of expensive and there are other companies out there but this is the only one I know and can say anything about.

 

My two sons and I have Collet communicators. They work very well. We use them for snowmobiles and for quads. They are pretty expensive as the last guy said but well worth it when you have young kids who could get into trouble riding if we could not communicate. Collet supposedly is the brand that the Canadian snowmobile police use (according to Collet slaesperson on the phone).
