Logging sailing session. Provides CSV file which includes GPS position, speed, heading, course over ground.

Also logs heel and pitch, up to 10HZ. Device needs to be fixed on the boat.

Log can be used with Trusail Viewer App or Njord Analytics

Quick Guide:

Phone is logging the GPS data, heel, pitch and heading of the boat.

Screen is locked and code is 0000. It can be switched off, but i keep it so water spray doesn't accidentaly stop the logger.

For using it only with GPS data, it is enough to have the phone anywhere on board.

To get heel, pitch and heading, phone needs to lie on its back fixed in the boat.

It can lie sideways or back/forward. This can be changed with "Rotate" button. Words Bow/Stern and Starboard/Port show how it should lie in the boat.

After fixing the phone, it is needed to zero heel and pitch. Phone can lie at an angle and be zeroed to still have good numbers.

Button "Team" is to change team name. Team name will be shown in the Viewer app

Button "Boat 1" is to change boat number to have different colors in the app

Button "Reset offsets" puts phone on its default heel and pitch

Button "Zero Heel" zeroes the heel. It makes a 3 seconds countdown so we are no longer touching the phone and then zeroes Heel.

Button "Zero Pitch" zeroes the pitch. It makes a 3 seconds countdown so we are no longer touching the phone and then zeroes pitch.

Button 10/s is frequency of heel/pitch logging. Can be 10,5,2,1 times per second

For faster classes is good to use higher values, for slower boats 1/s should be ok.

Button "Log" starts logging. To stop it you need to "Unlock" first.

After logging with button "Share" you can choose and send the log to your email/whatsapp/telegram...

Easiest way to transfer is just to connect the phone to hotspot you create with your usual phone. Phone spends small amount of battery when logging and can go through a few sailing sessions.
