Evening, wondering if a device other than GPS exists that can track how far one paddle their kayak… perhaps a kayak mounted stroke counter ?
Lots of free phone apps that do that and more.
If you really want to measure number of paddle strokes rather than phone/GPS to measure distance, I wonder if a basic pedometer would work? Those clip to your belt and detect the motion of the body to count steps. But whatever mechanism (pendulum, accelerometer/?) is used might also measure paddle strokes. You could clip it to a Velcro strap on your paddle.
