In other words, if you want to use a Class II (or III, or higher) laser for alignment, you can't. But, if you want to use a Class I laser mounted on the robot for alignment, at any point in the match, knock yourself out (though I do suggest making sure that the use of such a device doesn't violate any robot rules first--you never know when the GDC will slide in a rule about any robot with a laser must do a laser light show on the floor of the field or face a 50-point penalty ).

Yes, G02 is prematch only. But anything left on the field after prematch needs to be mounted on the robot...
