Rereading what I posted, nowhere did I say or imply or ... anything complaining. Simply passing on information that I had. If my simple comment was taken as a complaint, I apologize. It was not.
As for not being a boater ... really has nothing to do with needing or wanting a good flow meter. Several other activities ( RC cars, tether cars, RC Pylon racing, come to mind, not even mentioning my own specific needs ) where a flow meter can be valuable.
