One problem with any of the impeller driven systems is that all of them
measure your speed in relationship to the water.
That's just the problem! I guess it's sort of a frame of reference
thing, but I'm interested in how well my boat is performing with
relation to the water, not how fast I am going to get somewhere. On the
Potomac where I sail I have frequently found my boat splashing along
merrily through the water with no change in the shore line scenery due
to an oncoming current. I'm just interested in how well I am setting up
the boat. If I were interested in knowing how quickly I was gonna get
somewhere, I'd drive.
The above frame of reference problem is exactly what is keeping me from
allowing myself to buy a GPS -- something that the little kid in me
really wants!
We sail with the Tide! or maybe against it....I dunno; just so we sail!

PS Years ago I had a friend hover in an old Aironca (SP)Champ airplane
over the grass field airport by flying into a strong head wind. Kids do
the damnedest things....
