Share 'Pedometer ?? on a kayak?'

Is there such a thing out there like a Pedometer but for a paddle... like maybe a Paddle-o-meter. Be interesting to know how many paddle strokes that you make on a trip. Or could a person maybe set up a pedometer to do this? I don't know much about "Pedometers" myself. "=) this is what happens when I quit smoking and my analytical mind goes into overdrive" Guy
