True Wind Calculator in App
+ Wind Instrument early summer sale below
A new version of the SailTimer Wind Instrument RB™
was released this spring. With all-new firmware in the electronics, it required a new API
app on Android
to receive the Bluetooth transmissions. The newest version is available on Android now, and the new version 1.4 should be approved and in the iOS app store tomorrow (28/6/21). For manually calculating or checking True Wind Direction (TWD) and True Wind Speed (TWS), a hidden button was put into the API. This is not needed to use the Wind Instrument, but you may find it interesting to see how it is used by race officials, coaches, and for the crowdsourced wind maps
that we continue to develop (more about that in the coming months). Here is the secret of where to find the hidden button and how it works...
You don't need to be able to decipher the green text in the screenshot below, but it is an easy way to see if your Bluetooth data is streaming. Seeing the incoming data may also be handy for troubleshooting. And now you can use it to convert Apparent Wind (what you feel and measure when the boat is moving) to True Wind
(the actual wind movement, independent of the boat's movement - the same as in the marine weather forecast).
To open the simulator, connect to your Wind Instrument then long-tap on the beige wind cup icon in the upper left corner (see photo below). To stop, double-tap on the wind cup icon, and you'll see a confirmation message.
