What does a trap range look like, and how do the targets fly?

• The pit: its roof is level with the stations. Fifteen machines are fixed to its front wall.
• Groups: five groups of three machines, one group in front of each station. A painted mark on the roof shows the centre of each group.
• Stations: five squares of 1 metre, in a straight line 15 metres behind the front edge of the pit. A sixth is marked behind station 1 for the waiting athlete.
• Distance: targets must carry 76 metres, give or take 1 metre.
• Height: between 1.5 and 3.0 metres at a point 10 metres in front of the pit.
• Angle: as the setting table says, to a limit of 45 degrees left or right.
• Setting tables: there are ten. One is drawn by lot for each range before the competition, and the jury examines, approves and seals the settings.
• Distribution: in 25 targets the release system gives each athlete 10 to the right, 10 to the left and 5 to the centre.
• Release: by a microphone that hears the call, or by a person pressing a button. The target must go immediately.

The style is often called Olympic trap or bunker trap. Those names are common usage and not in the rules.

Fixed distances, heights and angle limits mean that a score of 120 on one range can be compared with 120 on another. Drawing the setting table by lot and sealing the machines stops anyone preparing for, or interfering with, a particular set of angles.
