[Paddlewise] Microphone for handycam

Hi there,
 
I want to make some videos explaining some kayaking drills. I have a
Sony handycam super 8.
 
The problem with handycams is that the microphone is in the camera, and
the voice sounds very far or dampened by wind and waves.
 
I have seen videos of people talking at the distance with very clear
voice and assume that they have a microphone and transmitter, and the
camera has a wireless receiver.
 
Anybody knows where I can get such an accessory?. Is it available for
any handycam or it requires a professional recording machine?
 
Thanks
 
Rafael
