I read about the Tandem Talk system with great exitement. Is there however a wireless system available. I would also like to hear of experiences of South AFrican based tandem riders as well to obtain a local system. I saw a Belgian system (not wireless) this morning. It is however deigned for Motor bikes. Some serious mods will have to be made for bike use. A velcro attached plastic helmet attachment will have to be made. The shopowner also knows littel about the sysytem. I do not know whether the boom is adjustable etc. lt will work I think but costs ZAR 460-00 (US $ 65-00) making Tandem Talk worth while. What worries me though will the wires not impede movement. We stand together and singly whilst climbing on the tande, That means if we sit there will be a lot of extra wire flapping around. It always gets snagged and the connections get damaged. That is why I think wireless will work, someting like Madonna wears when she sings with a wire down the back and a transmitter on the belt.
