Using Gun Starts and Markers on the Kairos 4

Introduction

Gun Starts and Markers are features of ChronoTrack Controllers you'll likely use a lot. Before you use these features, make sure you know the difference between them.

Gun Starts are time stamps in the data that you can use to sort and filter tag reads and use to determine the actual start time of you race. Gun Starts do not affect the structure of data files in any way.

Markers are the separating line between separate Sessions of data in a data file. Creating a marker separates the reads that were collected before the marker from those collected after. This is useful for scenarios such as when there is a common Start and Finish line. 

Zero Counts reduces the Unique and Total counts on your controller's main screen to 0. It also acts like a "light marker" in that it doesn't create a new session, but keeps all data in the same session while hiding tags prior to the zero counts from being streamed in the Middleware. You can choose to ignore zero counts markers in the Middleware to stream all tags.

The Kairos does not have a physical Gun Start button, but a Gun Start as well as other markers can be created on the device by simply navigating through two clicks on its 2 button menu. If you have the Kairos Companion App open, markers can also be created on its Marker menu there. 

Creating a Gun Start/Marker on Controller

1. From the Home Screen display on Kairos hit the Menu Button (≡)
2. The First Menu item on the list that opens up is "Markers". To select this Menu hit the Select (✓) button.
   
3. On the next screen, Select the type of Marker you'd like to create, whether Gun Start, Manual, or Zero Counts.
   

4. A message will appear on the screen indicating success and the type of Marker created, as well time created. 
   

   Creating a Gun Start/Marker on the Kairos Companion App
