:: :: :: :: We have been using the Velocitek Prostart. It works
:: :: :: :: quite well and updates fairly quickly. The features are
:: :: :: :: similar to the KVH unit.
:: :: :: ::
:: :: :: :: I believe it is also class legal as it is all integrated

:: :: :: ::
:: :: :: :: Don
:: :: :: :: :: Does anyone have a recommendation for a knotmeter? We've
:: :: :: :: :: been using a Speedmate for a long time. It's a good
:: :: :: :: :: unit, but is incredibly unreliable (maybe that's why
:: :: :: :: :: they don't make them anymore). I tried the entry level
:: :: :: :: :: TackTick (T035), but found that it reacted too slowly
:: :: :: :: :: and there is no way to adjust the damping. What else is
:: :: :: :: :: good out there?
:: :: :: :: ::
:: :: :: :: :: Thanks
