Default Help!!!:Speed transducer of SPEED2100(Navman)

Can anyone please tell me how did the speed transducer of SPEED2100
measure the speed of the boat?
I try to design my own display unit for this speed tranduscer. However,
i dont know the operation of the speed transducer, such as how i
calculate and measure the speed through the paddle wheel of the
transducer. When the paddle wheel is moving, how i going to know the
speed of the boat?
If anyone know, please tell me.
Thanks a lot!!!
