There are several games of TRAP. As mentioned earlier : TRAP / DTL / ABT / DOUBLES / ATA TRAP. They all basically have the same rules. A target is thrown from a trap mounted 16 yards / 15 meters in front of the shooting line. ISSF and NSSF have rules defining the height, angle and distance the target travels. Look at the diagrams below - To set the correct target height, a pole with a circular loop on top is placed in front of the traphouse. The target has to pass through the loop. Once the height is obtained the distance has to be set. Let's look at TRAP and DTL. In ATA registered trapshooting, the rules specify that targets must be thrown no less than 48 yards no more than 52 yards and should pass through the loop between 8 and 12 feet high at 10 yards from the trap. Shooters stand a minimum of 16 yards from the traphouses. In registered DTL the target should pass through the same loop (8 - 12 feet) but travel 50 - 55 yards. Shooters stand at the same distance 16 yards from the traphouse. For ABT, targets vary in height between 1.5 and 3.5 meters at 10 meters from the traphouse and travel 80 meters. For ATA Trap and DTL, the target path can vary between a defined arc (see below).
DOUBLES - Shown below are the two targets being released from a Laporte 2002 trap for Double Rise or ATA Doubles. With ATA, each target is worth 1 point - With Double Rise you score 5 points for hitting both targets and 2 points for only hitting one target.
On the right you can see two photos of the Laporte Doubles Trap. The furthest right shows the sequence of target release as the two targets travel across the throwing plate and are released at the front of the trap. The right target leaves the throwing arm first at 17.5 degree angle to the right, then the left target leaves the arm later at a 17.5 degree to the left, resulting in a 35 degree angle between targets.
