In 2013 the field will use 3M 8830 Silver Marking Film for vision targets. This is different from the Reflexite GP020, 50mm tape used last year. This is not provided in the Kit of Parts. I wish to obtain some so we can test our camera and code with the actual material used in competition. It is available on FIRST Choice if we can spare credits for a 27" long sample.
