I'll add that if you are planning on tracking the boulder, you will really want to take advantage of the time allotted for calibration at competitions (as guaranteed in section 5.5.8 of the manual).

The lights on the field at a competition are guaranteed to be different from the lights at your school or workspace. Since the balls are not retroreflective and you aren't shining your own light at them, the calibration you do at home will likely be a little off.

The green light isn't particularly well designed for bolder tracking- it is useful for the retroreflective tape on the goals because it creates a more or less known color that you can track irrespective of the ambient lighting.
