Name: BigFont Windsurf
Rating: 4 (3 reviews)
Author: Seli17

Sports: Windsurf and Kitesurf or other (Water-) sports.

Idea: show most important (8) values on ONE data field with 4 values in BigFont for easy reading under bad conditions (and for my old eyes).
WRITES TO FIT file, so you can see a graph minimal speed of  each jibe an maximum speed between jibes on the Garmin Connect

Shows on Top:
 - Time and ElapsedTime

In the Middle, there are two fields which can be defined via the settings dialog. (via the App on your mobile phone)
The values alternate between setting "1" and "2", so if you set them to the same value, only one value is shown in a field.
Possible values are:
 - HeartRate:                          in bpm
 - Max Speed 10s:                 is max of "Max Last Speed 10s" for the hole session. (in RED)
 - Min Last Jibe Speed 1s:    minimum of speed during last jibe.
 - Max Last Speed 10s:        maximal speed between two jibes. Where speed is taken as an average over10 seconds.
 - Average Speed 10s:         actual average speed over 10 seconds


Bottum: 
- Current Speed


Shows at the very top, 
- seconds since last lastJibe was detected.
  becomes red after 20 seconds. (no jibe in between will be detected, to avoid errors)

Shows at buttom left:
 - jibe count (in red)

Shows as vertical bar:
 - battery in percent in GREEN, becomes BLUE when BlueTooth is connected.

Settings can be changed and the license number entered via the Garmin Connect Mobile or Garmin Express UI. 
Here is how to do it: https://apps.garmin.com/settingsHelp.

It is a DataFiled, so you have to add it to one of your existing "Activity Applications". See also video https://www.youtube.com/watch?v=P5HYBabeB2s .

License: The application runs for about 5 hours without any restriction, only the horizontal bars when stop are gray, with a license they are red.

For a fee of 5 EUR, you get the unlimited time version. Then the horizontal bars when stopped change to red. (need a restart of the App).
Then the license dialog will be removed and writing to FIT is unlimited.

Please test the DataField before making the payment at https://paypal.me/Seli17/5EUR , then send me the ID displayed ON the watch, the type of watch and your country. 
It is a manual process, but I reply as soon as possible (less than 24 hours). Thank you very much.
