A South Korean archer who is legally blind set the first world record of the London 2012 Olympics in the men's ranking round.
Im Dong-hyun broke his own 72-arrow mark of 696 by three points and was also part of a record in the team shoot.
Alongside Kim Bubmin and Oh Jin-hyek he helped register a 216-arrow total of 2,087 - smashing the world record by 18 points.
The day's shooting got under way in perfect conditions, with the Korean trio setting the standard from the off.
They took the three top seedings, with world number two Im again leading the way, breaking the world record for the third occasion since the London 2012 test event.
