After five years, I think we need a real Speed / log / and water temp set.
(Yes, I have a GPS that give me speed over the ground - but I want speed through the water)
I have a Raymarine autohelm and a Garmin chart plotter and a Nexus wind instrument (may as well spread it around - lol)
Leaning toward this
but just leaning, have not purchased. (Also - not tied to this store - they just had a good link to it)
