lol I know mate. Last bit of info mate its set to 11.5bps, if they say its too high and you need to turn it down do this: hold trigger in and turn on marker, keep hold till light goes blue (will be white at first) go to solid green light, hold trigger and it will flash 3 times for 11.5bps, let go of trigger and pull 2 times 11.25bps (1 flash is 11bps)
EDIT: ive set it to 11.25bps so you should have no problems with gun chrono, if you do argue to get it checked on another chrono.
