Just buy a GPS. Cheaper and better solution. Plus you can play with it for navigation.

<br>A local guy here rigged the Speedtech Speedo up and he hung the impellers off the rudders with the pickups on the rear of the hulls. It worked some and broke a lot more. If you want more info on his setup email me but I'd just get a GPS.
