Anyone install one of these...

How do you calibrate that yarn for wind speed?    I wouldn't even need to buy any yarn....could just steal some from my daughter who knits.

No problem to mount.  I didn't see any reason I'd need to update the software.  Had also cut off the interface wires for the Raymarine autopilot when I installed it as didn't see need to connect with anything else.

I use yarn tied to the shrouds about 5 feet up. Red on the left, green on the right. I have enough yarn left for about 10,000 more summers.

I use ribbon on the side-stays and the backstay.  They keep sliding down and becoming less than useful.  Perhaps I will have to upgrade to this newfangled wireless technology next year!

Wireless yarn taped with electrical tape.

I use wireless (wifi actually) cassette tape; granted it doesn't last all season but one tape should last a lifetime, and no problems with signal quality. I prefer Maxell brand.
Also a wireless (cellular/4G) 15" Davis Windex with transistor and fiber optic based standoff to locate it aft of the mast.  Great reception, solar powered and interfaces with the optical network aboard.

Salty:
   I also tried cassette tape but discovered a disturbing feature: With a certain wind speed and direction, I could actually hear the music that was recorded on the tape. The disturbing part came when I heard Kenny G sounds emanating from my starboard shroud! I almost jumped overboard to escape! Fortunately, I replaced him with an old Jimmy tape and all was well. Now I use yarn because I still listen to all my cassettes.

  Long ago I raced against some one how used toilet paper for his wind indicator but  said he had to buy the expensive brand so it held together when it got wet. He was full of it so always had a lot of rolls around. It looks like another winter up here in Iowa, hope everyone has a merry Christmas.

Decided not to buy the Raymarine system...I think it's something that may break in a few years, and it's expensive.  I had wind indicators on the shrouds, but really didn't like them much.  Just bought a small masthead apparent wind indicator by Schaefer (Little Hawk race).  Should work out well.
