I'm interested in devices used to measure boat velocity (ie: sprint kayak) accurately... given flat-water conditions, little wind etc. It's important that we reach a high level of precision and interested in calculated stroke to stroke boat velocity (takes approx. 0.4 - 0.6 seconds for a single sided stroke) when determining performance variables.
I have considered impellers with a velocity sensor made by NK used for Rowing, but have also heard that there are high frequency GPS systems that exist and sample at 4 Hz? Can anyone suggest a product, or know the approximate cost of such a GPS device? Or are there any other devices that can measure stroke to stroke boat velocity?
Thanks,
