Shotgun start is a term typically used in golf tournaments where all players start their round at the same time from different holes on the course. Some synonyms for shotgun start include simultaneous start, mass start, and even start. These terms imply that all players begin their rounds together instead of starting at different times according to their tee times. Shotgun starts are used in tournaments to create a sense of excitement and equal opportunity for all players. It also enables the tournament to conclude at a set time, making it easier for organizers to manage the event.
