Above is GANNET’s new wind instrument. Actually only the part at the top is the wind instrument which is attached to a GoPro mount. It is made by a Spanish company, Calypso Instruments, which have an office in Florida.

They make three different models. Mine is the Portable Ultrasonic Solar Wind Meter. It has no moving parts and calculates wind speed and direction by using four transducers that send ultrasonic sound waves back and forth. The instrument continuously measures the time for these wave to travel between pairs of transducers. By calculating the differences in these travel times, it instantly figures out both the speed and angle of the wind.
Or so Google tells me.
This model has a small solar panel on the top and requires no external power.
It displays information on a free phone or tablet app.

Hi, I enjoyed reading your posts, which provide me with inspiration to continue sailing. Thanks for sharing your experience with the new wind instrument. I'm on my third wind instrument [1 TackTick, 2 Raymarine (which bought the former). Always nice to have an alternative. Peace and Fair Winds, Peter
Obviously I don’t know how the Calypso will work out. I have found over the decades that often you have simply to pay the price to find out. As I said, it will be great if it does what it ought to.
Of my providing reasons for you or anyone to continue sailing, I am pleased to have done so.
Your continued embrace of technology is inspiring. I turn off my phone whenever possible. JD in NZ
