No experience with Clipper brand anything. Never heard of them before now.
If all you want is apparent wind angle, then ISTM a Davis Instruments Windex would be both a heckuva lot cheaper and, probably, a heckuva lot more reliable.
The advantage, to me, of a masthead-mounted wind instrument, such as those manufactured by Raymarine, Garmin or Tacktick, is
in being able to get apparent and true wind angle and speed.
Heck, when our Windex got messed-up when stepping the mast, twice, we found we could get along without the apparent wind angle indicator altogether. When The Admiral and I were taking our ASA 101 and 103 classes, the instructor insisted we not
look up at the Windex, instead going by the feel of the boat and the wind on our faces.
Now, if what you want is a fancy-looking bit of electronics to impress guests, that's another thing entirely
. Tho, TBH, I'd question the robustness of even just an apparent wind direction indicator + display + cabling that costs only a few hundred bucks.
